That's interesting, something I never saw. What has been reported before, was the copper gradient that got hit. It's possibly caused by the same root cause (cdtv.device causing trouble to load assets).
For some odd reason, this doesn't seem to happen on FS-UAE (with FS-UAE Launcher). So, I'd recommend that. Meanwhile, I'm in the process of switching the version of the engine, in order to drop the problematic cdtv.device. Thanks!
