Weird WinUAE issue?!

Hi Guys

Wondered if you can help. I've attached a little EXE which plays two modules, one after the other. Problem is the PT replay source I'm using seems to bug right out in WinUAE. I've just tested it on my A1200 and all seems fine. Is it just my WinUAE config thats responsible for this? Any help would be great.

Just by looking at my crystall ball (also not enough information error, does the configurations even match?): Many PT routines have CPU delay loops that cause missed notes (or bad notes) depending on CPU speed and other variables.

The replay routine is fine, uses proper DMA wait. Also, it works fine here if I set the VBR to zero due to a bug (well, for me it is one anyway) in your code.

Code:
	lea	0,a0			; Fix this, needs the proper VBR
	move.l #$1b0f87,d0
	jsr	CIA_AddCIAInt
The VBR can be relocated on CPU's >68000 so if you assume that it always starts at $0 your code won't work properly (i.e. in this case no music will be played if the VBR has been relocated).

Before reporting possible next issue: identical hardware setup is not enough, also make sure OS setup is identical.
