Hacking Picodrive on RetroArch crashes upon starting up any 32x game

[Deleted member 386356]

When i try to load any 32x game on Picodrive, the RetroArch app crashes to the LiveArea. I've tried different solutions but nothing i've tried seems to work. When i load a regular Mega Drive game though, the emulator starts up fine, but any 32x game won't work at all.

Here is an error log:

Hm,I tried Kolibri,game started but performed poorly and so should all 32X games.
Guess it is the emulator.Maybe try an older Retroarchversion.I also face many problems with cores from 1.9
