![]() ![]() ![]() As said, DMA is far more flexible on the SNES, and far more bandwidth is available, so this isn't as onerous as it would be on the NES. All graphics data needs to be transferred to the 64 KB VRAM (which the CPU can access only via a port, as it is not on the A bus) before it can be used. Where would I begin to put the header?ĭo snes games utilize chr-rom, or are the graphics embedded within the rom as chr-ram? So for example, let's say I have a snes rom file that's empty, starts at $0, and goes all the way to $FFFF. If I want to create a header, where I'm the rom does it start? I know it's near the end of the rom. Right now I'm using bsnes for trying out writing. I know in the nes, the region $FFFA-$FFFF contains the pointers to the NMI/RESET/IRQ, does the snes use the exact same region?Ĥ. Do snes games utilize chr-rom, or are the graphics embedded within the rom as chr-ram?ģ. Also, commercially, the sprite dma is in $200-$2FF of the nes ram, so, is the sprite dma for the snes also placed within the snes ram?Ģ. Is the snes ram really $0-$1FFF? I ask because, I know the NES ram is $0-$7FF. Just wanted to give that brief background on my coding/writing history.ġ. I know 6502, I've hacked many games which a lot of people know, and I've now written 2 games from scratch for the NES. ![]() But I have a few questions as to understanding how the RAM/ROM works.
