Am I the person that mentioned that? Ah no, sorry if it wasn't clear, it was someone not in this forum. (rest of post) Thanks for your help, I'll keep that in mind. The intended use case is not for a game as such, so I can probably use most of the frame setting up DMA to start exactly as hblank doe...

So I'm trying to write to CGRAM during hblank, and the current method is that I use all 8 HDMA channels to transfer a total of 8 colours (mode 3, first two bytes are address second two are colour data). Someone mentioned that I might be able to transfer more by using regular DMA that is timed correc...

Did you use a UV light to erase it? Haha, this is an old thread. So I was trying to erase them by using the windowsill, and later a uv lightbox, of which neither worked. I eventually bought a specific small lightbox with a specific waveband (I'm not sure exactly what's different) and most if not al...

https://byuu.net/design/cooperative-threading has a bit about how things are synced in things like Higan

Without much knowledge of assembly it might be quite hard. If you output the song as SPC there are tools to turn that in full roms, but then ofc you won't have the sound effects...

I believe SNES GSS comes with some code to make things run? It might be in C rather than assembly Look around in the files for those. There should be code to upload a driver, then some to upload a song and start it, and then some to play sound effects. Run the first two at the start of the code, and...

Are you sure?
On each link there's a download link too. Under "downloads"?

EDIT: I'll add extra download links. Added.

Also, this piece of amazing music was released.

Hello! I recently went to the Revision 2019 demoparty, where lots of demos were released. Of all the demos, there ended up being 4 SNES demos, which I'm making a joint topic to discuss them all on. They are: [dl] SNES-NICCC-FX , by me. It uses the Super-FX chip to do speedy transfers of 3d data of a...

Read it again CPU side with lda $bf230e. Unsurprisingly, it's now BFh. Can the version code even be read? In other news, it now works. I switched to using fixed-mode, which solved most of it, but then I made all the VBP sections word aligned (like nocash suggested) and that fixed the rest. I thank ...

Did you get the variable-bit-length reads working? And are you still UV-erasing after each test? No, Yes. I have a few chips and I can erase 5 at a time, but it takes like 30mins to erase and 10 to flash. I'm doing some more VBP testing, and it seems something along the lines of "Writing to VD...

Apparently my SA-1's version code is 23h.

So, in short: it now works. kinda. In long: The issue was in the SA-1 boot. When booting, I leave emulation mode, jump to the correct bank, set up dpage and stack and then jump to a subroutine to set up the rest of the registers. This seems fine at first, until you include register 222Ah - IRAM writ...

So I've done another test where the SA-1 sends an interrupt as soon as it is turned on, and in software this interrupt fires but on hardware there is no such interrupt. This confirms that the SA-1 is not even starting, which means it's nothing to do with IRQs or DMA or bus conflicts or anything like...
