SnakeCoils it is quite possible there's some assumptions about little-endian-ness in the FPU emulation. A little while ago, I switched over to WinUAE's FPU code (because of FPU changes in WinUAE, and I didn't want to risk errors by maintaining the older non-WinUAE FPU code without time to test thoroughly, etc).

I'm not saying there definitively is a big-endian incompatibility in the FPU code (I haven't checked), but I wouldn't be surprised if there were, because the WinUAE-specific FPU code is of course free to assume x86/x86-64...
