Neo-Geo Pocket issues

Open Nausisauro opened this issue 3 months ago • 2 comments

First of all, thank you for continuing to improve this system for the RG35XX. I’d like to report an issue that’s been present since the first version of MinUI, and still persists in later forks.

With Neo Geo Pocket, when loading previously saved states, the audio breaks and sounds a constant high-pitched beep until the game transitions to a new level.

There’s also a bug in Sonic Pocket Adventure: if you press both action buttons at the same time, the character can pass through any obstacle in the scene.

race_libretro.so.zip

replace the file .system/rg35xx/cores/race_libretro.so with this one and report. It is actually the mednafen_ngp core used in onionos, if confirmed I'll update it in the next release.

Previous saves probably won't work anymore since it is another core.

Thanks!

The audio problem when loading is gone. Even the problem with Sonic's controls

The audio sounds choppy or slow now, but changing the "Core Sync" parameter to "NoFix" almost completely resolves it. Maybe this core has some other parameters to expose or finetune?

So the experience overall is much better than the previous one.
