Thank you for letting me run my favorite game, KOF95, in this version up.

When I actually ran KOF95, it ran very well.

However, after 3 or 4 stages, the game resets and jumps to the Saturn CD player screen.

I was wondering if this is just me and if there is a way to fix this.

SONIC3D commented 8 months ago

There are similar cases for this game reported in local online chating groups with the recent update.

Please try to provide the following information for better reproducing and tracing this potential issue:

  1. You console mainboard type.
  2. Boot ROM version(if you can see it on the bottom right of the splash screen after the Sega Saturn power-up animation).
  3. Console VDP type(Display type: PAL/NTSC).
  4. Is the power supply board modded or replaced with any 3rd party model?
  5. Is MPEG(VCD) card inserted.
  6. Is the joypad Sega original model or 3rd party model(include wireless receiver).
  7. Run KOF95 without start the game play, make it enter the demo play loop. Check if it will jump back to the saturn CD Player after several loops.

I'm having the same problem with my Saturn on Kof 95. Including with games that work on other Saturn's and don't work well on mine (Resident Evil, Mr. Bones, Deep Fear, etc.).

1 - HST-3220 2 - ver 1.01 3 - NTSC 4 - NO 5 - NO 6 - Original Joy Pad 7 - Yes, and during gameplay too (20 minutes in a demo play loop)

I tested it with some sector delay settings from 2k up to 12k and with 8k it was the one that managed to go the furthest missing one fight for the fight with Rugal.

I believe it has something to do with the music or sfx sounds.

With sector delay above 8k significantly increased loading time and also twice occurred to freeze the game on a black screen with sfx sound in a loop.

What version of KOF 95 are you testing? Note that based on game_patch.c file, it was only patched for the 2MB version of the japanese version (T-3101G). King of Fighters '95, The (Japan) (2M)

odiaboeeu commented 8 months ago

The version I used is 3M Hmm I'll try it with 2M

Maybe it would be better to make the same patch for all versions or at least put in the Readme which versions were used in the patch

Marvel super heroes US version could put the same patch they have in the Japanese version

odiaboeeu commented 8 months ago

Version 2m of the redump gave same problem (black screen and sound sfx looping)

Edit: I cleared the kof save I had and was able to finish the game without any problems

odiaboeeu commented 8 months ago

I've done more tests and it keeps crashing randomly, sometimes even characters from the team that stays in the stage have graphics problems in team China and team Korea happened a few times

  2. I tried "single play mode" not "team play" => it works normally
