My code doesn't use DMA; I don't know how to use it yet. :)
If you look at my code, the tiles in fact are copied excrutiatingly slowly to the VDP because I have to manually swizzle each byte on the 68000 as I retrieve it from the ROM (I'm using the exporter from the Usenti bitmap editor, it's for ...

Wow, that background looks amazing! I'll get to work in integrating it right away.
Thank you very much for the test in hardware as well! I noticed that I'd done something that made Regen unhappy, but it worked in Fusion. A Regen crash usually means I've not balanced the stack correctly or somehow ...

I had no idea. It's good to know that I'm in the presence of an expert. :)

Here's the fixed version if anybody is curious and wants to quickly poke some FM values.

Help with setting FM patch values
Hi, I'm writing a music player for the Mega Drive, but I'm having some unusual problems that I don't understand.
I've written a simple FM patch editor which exposes all the values for the operator lines so I can make new instruments and see what they sound like. ( zip ) A and B increase or decrease ...
