Topic: FB Neo Bugs Reports

[Nick Reynolds]

I know this is a hack game, but I am assuming it's still ok to mention a bug I ran into for it.
In Sonic 2 VS (md_sonic2vs), there are some issues with the graphics that can be found by going into a 2p versus match. I was using the 32 bit version of the latest FB Neo. I have tested this game on Retroarch Genesis Plus GX, and it doesn't have this problem.

Nick,
Thanks for letting us know, Will certainly try to get it fixed!

Hi Nick & friends,
Still trying to figure out the issues with Sonic 2 VS hack, this one is a bit tricky!

On Sonic 2 VS
I spent 2 and a half solid weeks on trying to figure this one out.  I'm afraid I have to give up.  I realize that this is a super, super awesome hack - which is why so much time was spent.  The only thing we can do now is, perhaps, get in contact with the hack's author(s) and hope they might have some hints.  Maybe someone can figure out how to do that?   (I did a little searching, but didn't have much luck...)

It seems like the background data is getting dma'd over in a messed-up state.

That's unfortunate about Sonic 2 VS, but I appreciate you taking the time to look into it. I don't exactly know how to contact the authors of this romhack either, but there does seem to be a link to the Discord server at the bottom of the page, which I imagine could be useful for getting in contact with them. https://shc.zone/

Gals Panic 3 (Japan) - using FB Neo x64 Windows DEBUG (05.11.2024 Nightly). ROMS are verified.

Sometimes when you get a perfect 100% the slideshow "reward" doesn't cycle the bonus images and instead shows corrupt negative and half loaded images instead?

I recorded it below (x264 & PCM) - see from 23s - since this is an "adult" game this recording may be considered NSFW.

Hi SoulReever,
Could you please attach a savestate from before it displays the bad image, or better yet: a input recording (from power on/with nvram checked)?

edit: I'm really going to need the input recording (replay -> record input, with options mentioned above) to debug this
edit2: ...I don't need any states or recordings, figured out how to get 100% every time

Hi dink,

I'll provide some save states anyway; because this issue mostly happens - but then sometimes it doesn't and it works correctly. Here's 3 saved just after getting a 100% perfect of 3 different stages.

Two of these save states demonstrate the issue I mentioned - and one shows it working correctly without any issue.

Notes: I've just tried the (Euro) release now and this issue also occurs.

SoulReever,
I remember trying to fix it back in 2020 with no luck.  Fortunately, this time things are working out!
Just need to figure out an issue with the ugly-ified girls, it's possibly a problem with the "blitting done" status.  hmm

best regards,

[dink]

Hmm, hopefully things are fine now.  Please try with new exe and see if you can find any broken scenes?

best regards,

Hi dink,

I've tested it with the latest Nightly and the broken scenes all appear to be fixed and are displaying correctly now. To be sure - I played through all 16 stages in both the Japanese & Euro sets just to make sure.

Glad it worked out and excellent work in resolving this - much appreciated!

Hi Nick Reynolds,
Just an update: I got 2 out of the 3 bugs fixed in Sonic 2 VS: in-game corruption and the titlescreen scrolling "chunky".  The only thing that remains is the level introduction screen.  I'll probably wait on committing this to github until I get the last one fixed, though - my dev. build is a mess right now!
