This happens when i try to load TZX roms with fast load enabled.
I have a XBOX One controller that i use with RetroArch. When the controller is OFF or disconnected, the games load fine. But when the controller is ON/connected, the games crash RetroArch on load!
I tried games such as Rainbow Islands, Robocop, Ghostbusters 2, etc. They all behave the same way.
With TAP roms, the games load fine regardless. But i only have a very small collection of those. My main collection is TZX.
I can replicate the issue 100% of times btw.
