I sort of got it to work by just putting a crap ton of sprites on one single tilemap and loading that ONE sprite tilemap into VRAM. Then and only then will it let me use those using byte 3 of the low table. It works OK except I can't have more sprites than will fit in one rom bank. I think I read so...

Are you sure? Byte 3, or the one that is in the cccc cccc format, points to which tile of the sprite to use from my understanding of it. If I start changing values of the 3rd byte, it just cycles through tiles. I mean I didn't just type in every value from 0 - 255 but it's like, in increments of #$4...

Yeah you're right. I got a second sprite to display by changing Spritebuff2 (aka $0600) from #$54 to #$50. So instead of it being equal to #%01010100, it's now #%01010000. I guess I forgot how binary worked for a minute which is why I couldn't figure out what exactly was going on with this part. I e...

This is one of those things that will leave people thinking "wow them hackers were too preoccupied with whether or not they could, that they didn't stop to think about whether or not they should"

But this is awesome though keep it up.

This does the actual DMA transfer to OAM. See the value that's getting stored in $4302? That's the address in main RAM of what gets sent to OAM. In this example it's hardcoded to 0x400. I'm not sure why. It's probably an error in the example. It should probably refer to the SpriteBuf variable label...

I suggest studying the OAM layout - you can find it here: https://wiki.superfamicom.org/snes/show/Sprites In short, you should have a section of RAM that represents what you want the contents of OAM to be, and then during NMI/Vblank (or force blank, where the display is turned off) you upload that ...

So I'm new to snes homebrew but I know how to program somewhat well. So anyway, I've been sort of crapping around with SNES code in order to build my understanding of how this works and possibly eventually make my own game for lulz (Flappy Bird, anyone?) There's a lot of helpful stuff on the superfa...
