When playing NHL '94 CD shortly after the puck drops and the actual game starts the game will freeze and no longer be playable. Sometimes it happens immediately after the puck drops, some times it takes up to a minute to freeze.

Firmware version: Jailbreak 7.4
Sega CD Model 2 BIOS 2.00

Final Fight CD Character or Enemy lock up, happens randomly but usually can get it to happen on the first or second level. The redbook audio will continue to play and other enemies or players will continue to respond but I can't proceed.

I am using my original US game disc on a US Sega CD model 2 with original PSU's. I can't reproduce the problem when I hook my Sega CD unit back up to my Model 1 VA6 Genesis. I have tried both my original disc, plus a burned disc from the Redump set.

Tried on both Official firmware 4.3 and Jailbreak 7.3 using both my Sega CD's BIOS and loading a region free bios'

.

Probably a low priority, but it would be great to have support for the 3D SMS games. The original LCD glasses won't work with modern displays, but could maybe be driven by the headphone jack once the RGB adapter is released. But for modern displays, the HDMI standard has support for 3DTV.

I believe 3DTV HDMI output is essentially streamed as side-by-side, and supports either 2x 1080p @ 24 fps or 2x 720p @ 60 fps. Obviously only the latter would be suitable here. Since SMS 3D originally works by alternating frames in synch with the glasses (60ish fps /2 for an effective 30 fps) the Sg would logically need to blank whichever half of the 720p side-by-side image is unused in each frame. This would also preserve the flickery nature of the original experience, which could be neat or obnoxious (or both) depending on one's point of view :)

The dither filter is practically mandatory for games like Final Fight CD that rely on dithering excessively. But it also produces artifacts or blurs out fine details, so you definitely don't want to leave it on for games that don't need it. This is pretty different from screen size or scan lines, which you'd typically set once and leave alone. My preference would be to have a hotkey. But I'll settle for anything quicker than opening the menu, going to "video", moving down a few lines to open "extra features", and then moving down a couple more lines to toggle the filter.

Toy Story appears to have a graphical glitch that appears at the top of the screen. Has anyone else seen this? I don't have the original cart or an everdrive (running ROM on CFW).

Thanks all

At the start of the game, within a minute and a half, the screen shakes similar to mode 7 on snes. On a real genesis, the full screen shakes without issue, on the mega SG the left side of the screen experiences video corruption.

Here is a link to a playthrough where there is no video corruption (Expected behavior) https://youtu.be/sjiGztXBOYE?t=71

You can reproduce the problem simply by playing up to this point on the first stage. It does occur again far later in the stage and happens again there.

Virtua Racing and Daytona USA both have the Sega Virtua Processor chip on their boards. Currently these games don't work on this custom firmware.

Hello, thank you for the JB and all the hard work you've done. I had a feature request if possible.

It would be fantastic if the cheat codes you enter for each game were able to be saved to the SD and used for future use. It's a bit frustrating not being able to save them and once the system is powered down they disappear from the cheat menu. Not asking for a data base or anything, just allowing it to save to the SD card similar to the SAVES folder, perhaps having a CHEATS folder so when you load the ROM of the game, the codes you've entered before will be available in the cheat code section.

It would also be awesome if we could have an additional button for scrolling through the letters and numbers for the codes. Right now you can only start from A and work your way forward by pressing the A button, setting another button (such as the B button) to go backwards (to start from 9 and work your way back) would be appreciated and make inputting the codes easier.

I understand this is a minor request and you are busy with other things, this would be so appreciated if it could be implimented not just for Mega SG but for Super NT as well. Thank you so much!

The newest version of Analogue's official firmware has been released, fixing many bugs and adding features over the previous version. It therefore makes sense to upgrade the jailbreak firmware to include these additions.

version 4.5 notes from Analogue's website:

• Player 2 controller can run the menu if it is a 3 or 6 button controller, and player 1 controller is not a 3 or 6 button controller.
• Different size font files are supported. If the file is 1K or larger, the first 32 characters are cut off.
• DVI Mode was added.
• Fixed scaler bug where the top scanline or two might not be visible.
• Scanlines have been totally redone. There are now more options to tweak and width is now adjustable.

(gen/md)

• fixed CD games that regressed in previous fw
• Some graphic issues on Mickey Mania CD and others fixed.
• Fixed bugs with Japanese Sega CDs.
• Silpheed and Vay bugs fixed.
• Popful Mail "CPU ERROR" fixed.
• CD bus timing improvements.
• Pier Solar cartridge + audio CD works and tested on US model 1, US model 2, and Japanese CD units.
• Added an option to automatically enable CD audio when CD unit plugged in.
• Fixed FM sound bug on Streets of Rage percussion on certain tracks.
• Fixed PSG sound bug (Phantasy Star IV).
• CRAM dots option added.
• X-Men 2 random character select on start is now random.

(sms)

• SMS Cropping setting added to crop the left side when a game used left cut.
• Fixed PSG sound bug (Alex Kidd in Miracle World).
• CRAM dots option added.
• VDP palette option added to select SMS or original TMS9918a palette for video modes 0-3.
• All 240 scanlines are now visible. Before, only 239 were visible.

In jailbreak 7.3 using the Game Gear core, the width presets for "4:3 for 16:9" are not correct.

Here are the values they should be for each height preset:

Height | 4:3 Width
5.0x      960
5.5x     1056
6.0x     1152
6.5x     1248
7.0x     1344
7.5x     1440

I applied the firmware, it worked/rebooted. I tested Master System games, these were all fine. I tested Game Gear games, these were all fine. (I never tried any Coleco stuff)

Mega Drive games just would not work though. I tried to load any game, probably 50 different Mega Drive games from Japan, Europe, USA and not one of them would load. What I got on both firmware 7.3 and 7.4 was just a black screen with random white chunky pixels all over the screen.

It turns out that all of my file extensions were actually .smd and not .gen. This is why I was getting this picture on my screen and no games were loading. I tried .gen ROM files and also renamed my .smd files and .gen files and every one of these ROMs loaded without an issue.

A confusing and annoying issue but easily resolved by just renaming any .smd file extensions to .gen

Describe the bug
A selected alternative bios for the Mega CD does not load again after setting one and saving the system settings of the Mega Sg, and then turning the Mega Sg off and on. Even though the "Use replacement CD BIOS" option is checked and the selected BIOS is shown on screen, you have to reselect the bios file you want to load again for it to work.

Auto region detection is turned on in the hardware menu, as required.
Bug shows up on a Mega Sg in combination with a PAL Mega CD 2.

To Reproduce
Steps to reproduce the behavior:
0. Make sure the auto region detection is turned on in the hardware menu

1. Check the option to use a replacement CD BIOS
2. Select a replacement BIOS loaded on your SD card
3. Save your settings.
4. Turn off the Mega Sg
5. Turn the Mega Sg back on
6. See the alternative CD bios settings in the Core Options menu
7. You should see that the box for using an alternative bios is checked, and you should see the path and filename of the alternative bios you chose and saved
8. Go back to the main menu and select "Run Cartridge"
9. The Mega CD will start but will still be running its default system BIOS instead of the alternative.
10. By selecting the alternative BIOS file again from the SD card and then starting the Mega CD again through "Run cartridge" the alternative BIOS will be used.

Expected behavior
Expected behavior is that the alternative BIOS should load that was previously selected and saved, instead of the default Mega CD BIOS.

In Alex Kidd in MW, when you get to speak with the first henchman before the R/P/S battle, when text is displayed a high-pitch tone is left active after the text is printed.

This does not happen on real hw (I know the game very well as this was included in every Master System II here in europe).

Using default audio settings.

Ultima IV for Sega Master System has strange audio glitches when running with 'Use FM' enabled, PSG audio sounds fine. These glitches manifest as buzzing or elongated tones when certain sound effects are triggered and at seemingly random (but frequent) times.

Tested in both PAL mode at 50 Hz output and NTSC Mode at 60 Hz output. Tested with genuine cartridge and with ROM dumped from said cartridge verified in GoodTools. Same ROM was also tested in Genesis Plus GX v1.7.4 core for retroarch with FM Audio enabled for comparison, audio sounded normal. Unfortunately, I do not have any FM audio enabled original Sega hardware to test this with.

To Reproduce

1. Toggle setting 'Use FM' in Core Options.
2. Run ROM (or original cartridge) 'Ultima IV - Quest of the Avatar (EB) [!].sms
3. Noticeable from start and seems to happen most frequently in battle, it seems as if certain sound effects 'clash' with the music. If left alone without interacting, music sounds mostly normal. Seems to be slightly more prevalent when playing in NTSC 60 Hz.

Expected behavior

possible there is a setting or something I'm missing???

Quick feature request. With everyone's idea of what a "real" Mega Drive should sound like being very subjective, it seems unlikely that we'll arrive at a default that makes most people happy.

How about a set of presets (compiled from the research Firebrand and Ace are doing) that can be selected. If we could also save current audio settings to a custom preset - even better.

For example we could have presets for;

Mk1 Sega Genesis
Mk2 Sega Genesis
Mega Sg Hi Fidelity
Custom preset 1
Custom preset 2

etc etc

Describe the bug
When loading Hardball '95 from the Genesis core, it gives an error message when trying to boot the game against a red screen.

To Reproduce
Steps to reproduce the behavior:

1. Load ROM 'HardBall '95 (USA).md'.
2. Run game past SEGA logo.
3. See error message - should read as such:

"Cartridge Error Message:
SRAM failure
Press RESET to restart."

Expected behavior
The red screen is expected to either not appear or appear very briefly before continuing to the game, without an error message. (See here or here.) The short red screen appearance seems to be more common in emulators, though neither seems to impede gameplay.

Hi,

when I understand the jailbreak correctly, I can save the state of the current running game
on the SD Card if i press down + START (Thats what I understand when I read the messageBox in the menu).
How is the correctly way to do it, or did I understand the feature wrong?

Regards
Petros

Some emulators provide an option to run Game Gear games using the Master System resolution, it would be great to have this option on the SG. Sonic Triple Trouble is already very playable in this state, and it could be fun to hack other games to take advantage of it as well.

(I realise this is perhaps beyond the scope of the jailbreak, but maybe Analogue will notice.)

When playing my original pal Mortal Kombat CD on my Mega SG with my pal Sega Mega CD Model 2, the sprites of the characters are glitching out during fights! Tried 1080p60 and 1080p50, pal and ntsc modes! I use the msg_firmware_verJB7.3.bin
All my other games are working fine, even my pal version of Final Fight CD... But Mortal Kombat is a sprite-mess... And before you ask, it is working fine with my original Sega Mega Drive!

A new version of the OS was released, with several bug fixes. As this jailbreak is based on 4.3, several bugs could be remedied by updating the jailbreak firmware to the new version.

Would be great if Mega SG was able to create a backup of a save inside a cartridge and if possible being able to "upload" this save to a cartridge again(after replacing a battery for example).

Thxs!

About 15 minutes into the game, you meet a character named Rune. Upon first meeting Rune, a specific song plays. During this song, a monotone sound coming from the Square 3 channel is heard. This problem does not occur if the Mega Sg is cold booted just before loading the ROM. It seems to only happen if this is not the first ROM loaded.

Issue is heard when using default settings. Adjusting the volume of the Square 3 channel to 0 seems to correct this.

I have attached a zip file containing two audio samples: the issue being heard and the issue being corrected by muting the Square 3 channel. The zip file also contains a copy of my save file.

The issue can be reproduced by following these steps with the save file:

1. Load any ROM.
2. Return to the menu and load the Phantasy Star IV ROM.
3. Load save slot 3.
4. Enter the town in front of you and walk north. Speak to Rune by pressing the C button.

When using a replacement BIOS on my Pal Mega CD 2 the controller is unresponsive in the Mega CD options menu. My Mega CD has a hardware JP region free BIOS installed.

Tested with JP US and EU region free l_olivera BIOS files. Tested with genuine 6 button and 8bitdo M30 controllers.

Controller is responsive if I boot with the matching JP replacement BIOS. EU and US do not allow me to move the cursor.

I own a genuine Pier Solar cartridge from the reprint run they did. If I boot with the Mega SG connected to my model 1 Sega CD I can’t get past the Watermelon logo screen. It goes straight to a red screen. Pressing the reset button doesn’t help. It does the same thing still. If I disconnect the Sega CD, the game boots normally.

I tested using the Rev A, B and C rom files and they will load but the game does not recognize that the Sega CD is connected - therefore the soundtrack disc cannot be used. This is with JB 7.4 firmware.

Expected behavior: Genuine game cartridge should load correctly when Mega SG is connected to model 1 Sega CD. Rom files should recognize when a Sega CD is connected

Actual behavior: Genuine game cartridge hangs at a red screen following the Watermelon splash screen when Mega SG is connected to model 1 Sega CD. Rom files do not recognize a connected Sega CD

Official 4.4 firmware has the same problem. Tested with and without cartridge audio enabled in SG settings

Hi,

Using "Final Bubble Bobble (Japan)" ROM, the game hangs if left in demo mode.
Just wait for some demo screens, and it will hang.

Any confirmation with cartridge would be welcome.

HI there,

There's this SMB homebrew conversion to Genesis, available here:
http://sonicvaan.sonicgamesdimension.net/mirror/rare/MULS_1.4.2.BIN

However, it doesn't display the backgrounds on the MegaSG. Resetting the game makes it work sometimes, albeit with missing score and information.

Any ideas on what's going on?

(Edit: I was using a bad rom from the AtariMax Coleco SD pack. Switched to a different rom and it works perfect now.)

On Official Firmware 4.3 and Jailbreak Firmware 7.3 the 6-button mode for Controller 2 is not working.

When doing the controller test in the Mega Sg menu, the X, Y, Z, and Mode buttons do not register for Controller 2. This has been tested with two 8Bitdo M30 2.4Ghz Controllers and a wired official 6-button controller.

The same behavior also appears when running a controller test ROM and was tested in 6-button games. (Tested on both the Mega Everdrive x7 and the Jailbreak Firmware Genesis core)

After flashing to Official Firmware 4.2 the issue is resolved, and 6-button mode works properly for Controller 2.

After flashing to Official Firmware 4.3 or Jailbreak Firmware 7.3 the issue reappears.

Whilst the automatic region detection feature works great, it can conflict with your saved video settings.

If playing PAL games at 60Hz output or vice-cersa, there is some visible shaking due to the mismatch. Of course, this is easily fixed by changing to a 50/60Hz option from the Video menu, but must be done each time a PAL/NTSC title is played for smooth output if in conflict with your saved video resolution settings

Would it be possible as an extension to the Auto Region Detection option, to automatically switch video output to 50/60Hz depending on whether a PAL or NTSC title is detected? Perhaps with the ability to pre-select a preferred video mode for each region?

This could possibly be an issue with any Sega CD game that saves directly to the RAM Cartridge. I'm using the db Electronics RAM cartridge and not the official Sega RAM cartridge. It works just fine with games that save only to the internal memory followed up by resetting the Mega SG, going into the Sega CD BIOS, and transferring the save from internal memory to the cartridge.

When starting a new game in Shining Force CD it detects that you have a RAM cartridge inserted, which is then chosen to start a new game, you input the main characters name, then it says "File Access Failed. Code 1" and just sits there until you reset the console.

Another Mega SG/Sega CD user from Reddit also experienced the same issue when attempting to save to the same RAM cartridge even after starting the original save on an original Genesis.

Expected behavior and actual behavior

I have an earlier model Mega Everdrive. Unsure if this would be considered the V1 or V2 model, but pre-X3/X5/X7 series. On a stock Genesis, pressing START+Down on the controller will open the in-game menu to access save state settings. On the Mega Sg, this key combination fails to switch into the in-game menu.

Here are two screenshots from the Mega Everdrive's settings, in case any options are relevant:

Steps to reproduce the problem

Press START+Down during game play. The Mega Everdrive should switch into the in-game menu automatically.

firmware version

Tested with both official firmware v4.2, 4.3 and Jailbreak Firmware v7.3.

Also tested using both an original wired 3-button Genesis controller and an 8bitdo 2.4g wireless controller, just to rule out it wasn't a specific controller issue.

relevant Mega Sg settings

Also tested with both controllers in "Passthrough Mode" as well as "Hotkeys Disabled." Also ensured that no existing Mega Sg hotkey shortcuts were set to the same START+Down key combinations.

This core no longer has the options to apply advanced filter settings, swap left and right audio, or cartridge volume adjust. There was no mention of this downgrade, so perhaps it was a mistake by the writer of this firmware.

Describe the bug
The Genesis game The Lost Vikings has an option screen that lets you switch the game to one, two, or three players. It has some sort of detection behavior that only lets you select three player mode when there are 3 controllers plugged in via a (Sega, not EA style) multitap.
On Mega SG, it only lets me select one or two players.
The exact same setup of multitaps, controllers, etc with an actual Sega Genesis lets me select 3 player mode.

To Reproduce
I can repro this behavior both on everdrive (with the in-game hooks turned off, because weird button combos from the multitap often hit the the right combo) and with an actual cart.

Firmware version
JB 7.5

Describe the bug
When playing these titles on the Mega SG in the Zero Delay mode, the pitch incorrectly shifts significantly when playing music. This issue does not exist when using either of the buffered video modes. Populous, Budokan, and Onslaught have only been tested with ROMs, while Test Drive II: The Duel has also been tested on cartridge.

To Reproduce
Steps to reproduce the behavior:

1. Toggle setting 'Buffer Mode' to Zero Delay.
2. Load ROM of selected game.
3. Run through title sequence.
4. See (or, more hear) error. You can get a better view of how off-pitch this is by switching back and forth with the buffered modes.

Firmware version
This issue exists with both the most recent official firmware (v4.5) and jailbreak firmware (v7.5). In my testing, previous firmware releases have also exhibited the same issue.

Relevant Mega Sg settings

Buffer Mode:

(From the Mega SG Reference Manual v1.3)

The buffering modes on Mega Sg address the issue that the Genesis/Mega Drive’s native NTSC frame rate is 59.92275fps and the PAL rate is 49.70146fps. A CRT can display these frame rates with ease but modern displays and HDMI interfaces expect either 60fps. 59.94fps or 50fps and are generally not tolerant of refresh rates that vary from too far from the official frame rates. Mega Sg has three modes that deal with the frame rate differential in different ways.
Fully Buffered Mode buffers full frames to maintain the timing of a 59.92 frame rate using only 60fps. This mode avoids tearing at the cost of latency. Mega Sg must render at least 1 frame ahead of the game’s internal rendering to stay ahead.
Zero Delay Mode speeds Mega Sg up to achieve a true 60fps frame rate, a speed difference of 0.13%. There is no latency penalty with this method but this method causes Mega Sg to jump ahead by about 1 second every 10 minutes compared to an original Genesis/Mega Drive.
Single Buffer Mode is something of a compromise between the two methods described above. Like the Full Buffer option, the original timing is being generated within Mega Sg. Unlike the Full Buffer, only a portion of the next frame is being prerendered, giving latency of no more than 1 frame depending on when the player activates an input. The drawback is a recurring retrace line that is visible once per every several seconds.

Note that this setting only appears when the system is in Advanced Mode.

Additional context
This is often notable at transitions, which create a sharp pitch bend if music is playing between shots. However, this isn't consistent, and several games (notably Populous and Test Drive II) shift pitch heavily on static screens.

It should also be stated that this has also been tested not to occur on the original Genesis hardware, through referencing screen and audio recordings on the previous games and with personal tests with Test Drive II: The Duel.

Expected behavior and actual behavior

EEPROM type on the Rom of Rockman Mega World & Mega Man The Wily Wars fails to save. I'm able to test this with the Alt version of Rockman Mega World (normal one is already SRAM Patched (labeled incorrectly if it's from Unpatched EEPROM-Save Games for X7) according to the Mega EverDrive X7).

Mega Man The Wily Wars has the same issue.

firmware version

JB v7.4

Given all the different cart types the Mega Sg can play, adding cart dumping would be a nice bonus. On the Super NT I have really enjoyed backing up my library and using my original copies between my devices. It's also been wonderful to back back up may save ram too. The only other option I wish existed would be to inject the the save ram back on to the cart as this would make swapping batteries much easier.

After powering off and on the selected alternative Sega CD Bios is still checked in the options, But the Sega CD 2 (european PAL version) starts with its own Bios version.

The only way to use an alternative bios (after powering off and on) again ist to switch to another alternative bios.

Describe the bug
Unable to load alternative Mega-CD bios

To Reproduce
Steps to reproduce the behavior:
Make sure the auto region detection is turned on in the hardware menu
Check the option to use a replacement CD BIOS

Expected behavior

Firmware version

Hi,

Using "Rastan (USA, Europe).sms", music with YM enabled is missing a lot of notes.
Seems like a timing issue to me.

Any confirmation with original cartridge would be welcome.

Thanks!

Expected behavior and actual behavior

Not have graphical corruption

Steps to reproduce the problem

Starting Mega-CD while attached to the Mega-SG - tested with all Bios's named in smokemonster Mega Everdrive pack, region free and original. All have issues especially in the memory management screens. Also tested loading via the Mega-SG and via Mega Everdrive X5. The Mega-CD acts normal with no video corruption in BIOS or games when connected to a US Model 2 Genesis loading the BIOS via the Everdrive.
