What the title says. Fast Loading crashes the emulator and RA. It’s completely random though. Some games will load successfully and some will crash. Try “007 - A View To Kill” if you want to reproduce the crash, it’s one of the games that do have issues.
The alternative is to disable the option but that makes loading Spectrum games a nightmare. Takes 10+ minutes for some games to load, even with RA’s own fast forward function.
Is there maybe a different core somewhere we can use?
