Blah, CPUWIZ and Batari should just get together and make a Harmony/Versa combination that plays games off SD card, has Pokey, XM RAM expansion, and maybe the HSC.

Knowing Fred, all but the Yamaha chip will be in the H2. ;)

Hmm, no, I take that back.  He will not be able to emulate the PIC functionality, that the VersaBoard now has. :grin:

I may be second guessing your Versaboards purpose.  It would be nice to have a cart that could directly attach to the PC.  Hit compile and automatically download to a real 7800.  That's make testing go much smoother.

I think you should learn how to program the 6502, in assembly language. :P

 

The purpose is to let developers release carts, not multicart or flash nonsense ROM's.  Hands on, real cart, it just works.  And the more I mess with this thing, the more unlikely it will be for someone to copy it for repro purposes.  Of course that would be up to the person releasing the cart.

Hmmn.. so, if the PIC isn't being used to offload I/O tasks (like direct transfer from a PC) then is it a cooprocessor for games?

 

I could see hardware assisted tile/sprite shifting to simulate smooth vertical scrolling.

I didn't read how much RAM would be included with the Harmony Nukem Forever...
