I read a translastion of your topic on romhacking.  Are you still having problems with the Sega 32x version?  What was the problem?

Also, what sound driver are you using?  I've used an early version of the z80 XGM driver in my games but it isn't very compatible :(

The problem is that the subroutine is called with the instruction bsr asm - and such bsr only performs a 16 bits jump, meaning that it only can jump roughly 32K back or forward. If the code where you call the subroutine with parameters (which originates a bsr) is more than 32K ahead of where align heap is located, bsr cannot reach it so the assembler fails.

XGM sound driver.
