Hi !

Thanks for this wonderfull SDK !

I work on a fighting game and I have good results under emulator but many glith on real hardware with NeoSD cartdrige.

Here a screen shot on emulator :

Does this resonate with you?

Hello Jul,

I know that the timing for writing to the Video RAM is fairly sensible, and sometimes the emulator is more lenient than the real hardware. This has been reported at least once by the creator of Shadow Gangs Zero.

Based on https://wiki.neogeodev.org/index.php/VRAM, you might want to wait some cycles between writes to the VRAM to make sure the operations are correctly read by the graphics chip.

Hope that helps
