This is old known problem, I debugged it about 1.5 years ago..

This game contains some very strange code (self-modifying code, trace mode tricks, etc). This was probably meant to make cracking harder.

Unfortunately game expects 68000 instruction prefetch cache to work slightly differently than UAE's emulation. There are plans to use mame's 68k prefetch code but Bernd haven't tried it yet. (No, I don't want to mess with CPU emulation code..)

It is strange that only the trained version has this code...
