Well, as was explained before, the MB routines detect the CPU mode at a certain point, and all the I/O timing after that is based on that detection. Probably, it detects the CPU mode somewhere in the period before switching to Z80 (during initialization or loading), so it detects a R800. If you then switch to Z80, the replayer's timing is still done for the R800, which means that it puts in very long delay instructions to slow down the I/O access... Which the Z80 can't handle. So... Basically Alex Wulms has the correct solution ^_^. Or you could keep the R800 disabled all the time. ~Grauw --- Ushiko-san!
