Issues with DMA
So I have a DMA queue specifically for VRAM and CGRAM transfers that's processed in v-blank. Everything seemed fine up until I noticed DMA would occasionally write to the incorrect address, despite verifying both the source and destination addresses in a debugger. Is there a specific time I'm suppos...

Re: SNES Newbie
That's super cool congratulations on your progress! :) Now, that you have a huge animated sprite, some HMDA gradient, and sound working, you're all set to make a game! Do you have any plan for it yet? Something akin to Super Smash Brothers, though not entirely sure yet! :lol: There are still quite ...

Re: SNES Newbie
Hmm, I've been trying to look more into the SPC-700 and implement the SNES GSS audio driver for my own game engine, but seem to have an issue.

SNES Newbie
Hello! I have recently taken an interest in programming for the SNES, and I've gotten to know the basics of the console's architecture. I've messed with sprites, backgrounds, tile collision, and simple horizontal-DMA effects, but I feel like I don't know enough to advance further into a large projec...
