[Request] Real machine test
Can someone test my ROM in a real gen/md?
here!
If you have a male plug on the ext port please test it (with a controller)
Thanks

Reposted... Please test (again )
Well option A has a yet unknown problem.
When A is pressed:
In Regen:
An exception occurs (probably address error), the screen is grey. But when start is pressed the program is resetted and something goes wrong.
In Fusion:
The screen deforms (plane dimensions changed) but the mappings are the same.
In Gens:
A gradient from black to red (should be blue) appears, but scrolling it makes it weird green and flicker (raster bugs)

my TMSS bypassed MD2 gave white screen which means the VDP is not initialized properly or you trigger an DMA during reg init and it crashes the system.

CLR, BTST and some other instructions cannot be used with VDP
EDIT: Latest greatest still shows white screen, and $2700 in SR will not prevent DMA's from happening, put a $80 into last DMA reg, if you don't have it there.

I think you may be confusing DMA and interrupts. Both of the measures you've described disable interrupts and have nothing to do with DMA.Jorge Nuno wrote:Well I though you were referring to Vblank DMAs, before the code inits properly. That's why the move to sr is right at the start.
But now I'm doing a "MOVE.w #$8100, VDPControlport" after deactivating HBL/VBL. This should end with the accidental DMAs...
