I've been hunting the cause of that issue for months.
Turns out doukutsu-rs implementation of events that perform a jump to another event (<EVE, <**J, etc.) do not clear the text box which ruins certain in-game dialogs completely.

should be a pretty straightforward fix

Anytime armv7l devices will be supported?

Unless otherwise specified, these issues were all replicated with the default data. All of these issues were experienced on build
0.99.0.386-master.

• Armored Gaudi projectiles do not bounce off walls as in vanilla. Instead, they disappear after hitting a wall. Vanilla behavior screenshot. Doukutsu-rs behavior screenshot.
• Armored Gaudi projectiles are aimed differently. One example would be in Lab W. The first armored Gaudi will throw it's projectiles higher when you boost up in vanilla. But in doukutsu-rs, it always throws it's projectiles so that they end up hitting the slope. Vanilla. Doukutsu-rs.
• Red Ogre does not drop exp as he does in vanilla. Screenshot

to reproduce it, you go into a room with minimal size while being in the corner of the camera

Since most ports give you a little reminder of his birthday on April 29th, would be nice to have something of it's own built in.

The player simply keeps "jumping" on NPCs that have a positive vertical velocity.

Especially noticeable in Egg Observation Room lift.

• Specific Challenges will only draw entities once fade transition is done
• Wait Fade Left and Right (Scene #90 & 0092) transitions end too early
• Balcony Ravils wont stop hunting Quote even if he is out of range
• If Possessed Misery is knocked out, she will play her death animation again if the Undead Core is defeated
• Curly's Nemesis shots originate from in front of Quote
• Curly's Nemesis does not emit sound
• Heavy Press Does not emit hurtsound
• Kazuma doesn't catch Sue in the Normal Ending cutscene
• A newline is skipped when Balrog says "All right, hang on tight!!"
• Random characters will speak empty newlines even if there is no remaining text (Labyrinth Exit Cutscene Balrog)
• Muscle Doctor death animation is VERY broken
• (Kaitlyn) Booster particles should be behind Quote
• (Kaiylyn) Balrog 2 (Malco) some bullets do not animate
• CS+ shouldn't reset I-Frames when you enter the inventory/run a tsc event without a <KEY/PRI

Just noticed this while playing with a friend. Not sure if this happens on the Switch version.

The slower the camera moves, the more apparent it becomes

Entities also misalign at certain circumstances (harder to replicate)

see screenshots
on latest commit btw on windows x86_64

F to textboxes :(

This only effects enemies that are new to CS+ (like the Curly clones). I think this bug also disables how the enemies work. Probably only happens on PC.

So far, Balrog seems to be the only one with this issue, as other NPCs don't

#it doesnt support joystick

rappidly press x,q pass the cutsinse witch mustnt happen but its good bug

#the screen some times spilt i half like old movies but colorful
#juily fish shouldnt show the number of dumge it takes
#i can skip that rabid mimiga in bushlands hut mean exit the room without killing him
#lights doesnt work in small room(it works in android)
#when balrog came in the dog bark stuck at his mouth keep opend
#toroko turn boss verry fast
#when balrog try to pull the heavy rock ,qouts gun pushed back to right , i am not sure is this a bug or fixed cuz its adult joke
#cant pass laybrinth funs
#qout dispares when he drown after core fight and reaprears when he got air tank
#water way dorw water (not real water cuz it doesnt move) in some places not supose to have water usely in top right or left
#dont even try water way shortcut its x2 harder than libernth funs
#red ogre drop no xp
#congratilation music never stop

#there is some auto frame skip in hell
#challenges are already opened
their wr used as hell timer (means if you get under 3 mintes in any challenge ,the game will replace qoute with sue in the main menu)
#machine gun challenge:
-due screen wide ,cairly move from race c to d without reaching the end of the screen
-before ending that challenge ,the disparing boulders it has a bug not sure how to say it , it diapers verry fast but cairly can walk in thier corner
#sand pit
-when qoute got the dog and even restart the do still on his head not in his poket
.didnt finsh it.
#sanctuary time attack
-due screen wide delets appears too soon
#wind fortress

• cairly clone are inveseble ,dont move ,it hp 1000
  -gclone cant close his screen
  and insted of he somon cloned cairly a blue critcher apears and disapears on top left

I installed the game and the files, when it starts I thought that it was muted, but when I put my ear close to the speaker I realized that it wasn't muted but the sound was ridiculously low (I tested in another apps, and no the problem isn't the phone) when I go to the options menu the audio slider was in the minimum possible, but for much that I press and slide it didn't move, it didn't happens in older versions.

There is no button for the map, if you click map system in inventory it gives you inventory screen without description pad (my english bad, sorry for errors)

Sometimes level 3 missiles go through walls, I believe it's due to the random off-axis movement they have. They skip the check for the perpendicular wall collision because they move through the parallel one instead. Adding an (inaccurate) test for the parallel wall collision fixes the issue. Direction::Left if self.flags.hit_top_wall()

doukutsu-rs.x86_64 with gog data folder
challenges are missed up
#they are named easyMod/mod/...etc
#curly story but qoute is showed insted
#time trial some aria art is missing in the first map only
#boss mod same map issue and qoute start near monster x
#kaze/mod also map art missing

Nemesis here when qoute take booster 2.0 it works along side with 0.8 the tow work at same time (must open menu and acuire it manly to fix it) here is the link https://youtu.be/hktqHKEJcOM

-fazz core doent wait for qoute invencebilty (it hit him towice in row)

• nemesis doesnt directly levelup when taking one xp
• the second ghost cat is insaid the top up blocks

and with switch data qoute start challenges a little bit to the left

I tried using the Spanish translation I used with a different Cave Story engine to see if I would run into one of the same issues I had noticed there, and it seems that this also has it. Basically, accented characters and upside-down exclamation/question marks that are used in Spanish aren't appearing.

I actually spent time fixing this issue there, so I have a pretty good idea of why this is happening. When I was working on this originally, the problem was caused by interpreting the byte values in the plain text decryption of the TSC files as UTF-8 encoding, when in reality they were encoded as Windows CP-1252 (or ISO-8859-1, which is essentially the same in terms of what values correspond to which glyphs).

This hasn't been causing an issue so far because CP-1252, UTF-8, and UTF-32 all use ASCII for their first 128 characters, so the values given by incorrectly interpreting CP-1252 as UTF-8 have always been the right ones.

it seems that it resets it before the tsc event starts rather than at the end

See scrnsht

• Water push tiles (0x80 - 0x83 and 0xA0 - 0xA3) do not animate
• SFX continually plays

Save file for testing

Can't enter the assembly hall in Mimiga Village using Steam files or as Curly Brace with Switch files.

• Super Missile Launcher has too small damage and the missiles go through walls sometimes
• Missile Launcher wasn't implemented because the former is broken but the code is mostly identical so it's a matter of copy and paste once SML is fixed.

maybe the npc's gravity value is too high?

from Kayo on discord:

hey just thought i'd tell you, as I forgot to say it
in d-rs, there might be an accuracy issue involving horiz/vert triggers
in CS Freeware, if you have a trigger over spikes, the trigger takes priority
in d-rs, the spikes kill you
so basically, if you run into spike tiles with a trigger over them in freeware, you run the event and live
if you do it in d-rs, you die

not only in water way but in some places that has water
like this https://youtu.be/zEjuaK4Z5sk

It's more a request, in my phone the controls are at the middle of the screen, it's not bad but it makes difficult on boss battles since they are in a strange position. It would be great if I could change the positions and stuff. Thanks

When running the latest doukutsu-rs build, opening a context menu in ShareX (possibly other software) causes the game to crash.

Interestingly, it doesn't happen every time, but it happens most times.

The error thrown is thread 'main' panicked at 'attempt to subtract with overflow', src\lib.rs:134:22

GIF Demonstration:

Curly's Story should appear as a seperate option from challenges but is instead inside the challenges menu.

maybe a rect typo?

Controller support on android should be added, thanks for considering!

I've been considering relicensing the project under modified MIT license with one additional clause that explicitly prevents it from being used... in one specific way that could bring Nicalis' attention in a bad way.

i have no idea what could've happened here, i think it worked fine a few builds ago?

might've been a typo?

When running the latest build of doukutsu-rs, Tiles seem to jitter at random intervals.

See a demonstration video here: https://imgur.com/a/nWdmg44

Timeline of the video is as follows:

• 20 seconds: You can see the door flickering as I navigate the Start Point map.
• 26 seconds: You can see the tile borders glitching at seemingly random intervals.

<MSG<TUR- Polar Star -
The most basic gun.
It bears the mark of Polaris.
<WAI9999<END
maybe it's the way the tsc gets "compiled"?

Not sure why this happens but for some reason pressing down while shooting does that.

this should be pretty easy to fix

When I run the game (I'm using the newest version from GitHub releases), it ignores whatever external audio I have connected, and decides to turn my normal volume down, so when I don't hear anything, I accidentally blast everyone around me with the cave story main theme.

Is there a way I could fix this?

• Red ogre projectiles spawn at wrong position
• Balfrog spawns at wrong position on switch
• Misery orange bats immediately die during undead core fight
• Bosses don't show damage

The indicators that show taken damage/acquired exp aren't implemented yet on d-rs.

• Teleporter SFX does not play during cutscenes
• Kazuma's bike does not emit smoke after crashing it
• Labyrinth Balrog boss fight missles emit trails on the wrong end
• King will face the wrong way during the Rabid Toroko cutscene
• Curly still shoots Machine Gun bullets despite holding the Polar Star in the Labyrinth
• Curly's air bubble does not show up when she turns her back after Core boss fight
• Curly isn't launched to the left after getting blown up in the Core room cutscene
• The Sisters don't close their mouths to getting damaged or defeated
• Orangebell bat sprite is stuck to flying left
• Gunfish aren't bobbing
• Player 1 vanishes if player 2 drowns
• Ma'Pignon only faces left instead of towards the player when beaten
