That's the problem I have, however it happens here even with Blizkick *, so it's not about compatibility problems of a module or such, but a problem with the copied ROM in RAM when the available fast memory is in one specific slot on the BPPC, I'm out of options/ideas, I guess I'm gonna have Jean Jacques B.(amigacenter) in France to have a look, it's quite expensive tho, around US$50 just for shipping, plus repair cost if needed plus shipping back...
I shouldn't complain, we all know Amiga=Expensive :-(
thanks!
