ems-flasher's Issues

Extract ROM bundled in MENU.GB

Is there a way to extract a ROM which was bundled unintentionally with the MENU.GB file?

I flashed some samples into LSDJ a while ago but I don't have the ROM file anymore - need to get this back.

Menu/game not loaded after transferring

First off, I wanted to say thank you for making this! I've been struggling for weeks with the Windows drivers with no luck, so I'm glad this alternative exists for Mac.

My issue is that after I copy a rom to the flash cart, and then put the flash cart in a real Gameboy or a real Super Gameboy, the screen is only blank after the first flashing "Gameboy" logo.

I wonder if the problem is with menus.gb.

Here is my terminal output:

Daniels-MacBook-Pro-2:ems-flasher Daniel$ ./ems-flasher --format --verbose

It looks like when writing the menu rom, it stops at 3% before moving on to writing the game rom. Do you have any suggestions?

Thanks for reading.

Writing is always stuck on 0%

The command
sudo ./ems-flasher --verbose --write romname.gb

always results in:
trying to find EMS cart claimed EMS cart base address is 0x0 Loading the menu ROM...Writing /usr/share/ems-flasher/menu.gb [MENU#]... 0% 00:12

and it never continues from there.

I'm running Ubuntu 16.04.1 LTS 64 bit.

Outdated information in website

Hello again. I figured out why it was too hard for me to find this Git repo. http://lacklustre.net/projects/ems-flasher/ is full of outdated information about this project in nearly all sections (with broken links also), and this repo is not named anywhere there. Could you please update the page for newcomers? Or just redirect people to this repository, which readme.md is quite complete.

Thanks!

GBC ROM flashing leads to logo lockup(Nintend-)

It seems that whenever I try to flash any GBC ROM the cartridge is unable to start either on a Game Boy Light or a Game Boy Color.
The Nintendo logo is incomplete and locks.
This happens with all GBC ROMs I've tested so far.
I think it may be related to the menu ROM for GBCs.
I don't have this issue when there are only GB ROMs on the cartridge.
Flashing seems to be successful, no error messages even with the --verbose option.

GC version?

Turns out the GameCube USB memory adapter from the same vendor has the same vendor and device IDs, and the vendor actually seems to ship the same driver for all their cards. Are you aware of anyone having tried this software with the GameCube version of the gadget?

_BSD_SOURCE deprecated in glibc >= 2.20

Building with -Werror fails when building against glibc >= 2.20 due to a deprecated macro. According to man 7 feature_test_macros, the macro _DEFAULT_SOURCE should be defined in addition to _BSD_SOURCE to get around this warning.

Menu functionality appears to be undocumented for the user

How can I use the menu functionality? There's no --help info, and it's not in the manpage. Is it even complete?
Can I just do this:

cat menu.gb i-can-assure-you-i-ripped-this.gb not-pirated-and-totally-legit-game2.gbc > no-copyright-infringement-here-menu.gbc

and then flash no-copyright-infringement-here-menu.gbc? If so, to which bank?

If the project needs user-facing documentation, I'm happy to write it, as long as it doesn't involve interpreting code lol. I don't do C normally.

Multi-save manager

Hello. I read in the documentation manual that:

The static RAM is not paged and there is no partitioning mechanism that would
allow it to be shared by multiple ROMs. That means when a ROM save data to
the SRAM, it will likely corrupt previous data placed by another ROM.

But there is a menu that manages several ROM and several saves (in only one .sav file/SRAM module) written by Mottzilla: https://thegaminguniverse.org/ninjagaiden4/mottzilla/smartcard.html

The problem: it is coded over a 'hacked' version of the official EMS flasher program, which is Windows only and a pain in the ass for driver installation (even more now using Windows 10).

Could be possible to integrate this kind of menu or manager into the ems-flasher project?

Invalid header for menus.gb on write

Hey there,

Trying to write to my cart is giving me the following error every time I try to write a ROM (./ems-flasher --verbose --write lsdj.gb):

trying to find EMS cart
claimed EMS cart
base address is 0x0
ems-flasher: invalid header for /usr/local/share/ems-flasher/menus.gb

I went ahead and moved the cloned repo to /usr/local/share/ to solve a previous issue where it couldn't find menus.gb (project root apparently needs to be /user/local/share/ems-flasher/), however, I can't seem to get past this issue.

Deleting and formatting from the cart works totally fine, albeit needing to unplug/plug back in the cart after every action (otherwise the program can't seem to find the cart). I'm on OS X, with the latest build dependencies. The compile (make) seemed to run just fine.

Let me know if you need any more info from me for debugging!

Trailing whitespace causing installation issues
