@Retro Python I use zipped files, the strange thing is that i didn't change anything other than update Retro station and Launchbox to the newest version and all my 600 games worked fine till one day I wanted to show it to someone and I got this error, It look like a issue with WHDload.
I also have Amikit (Best Amiga emulator from this time, and made a update of the program, but so far as I know Launchbox/RetroArch use there own version (I think)
I use PUAE Core.
