A project log for SNES DRONE

A cartridge for the SNES (Super Famicom) that uses the built-in wavetable chip to finally turn the console into a synthesizer!

Made some minor changes to the STM32 firmware today and was finally able to test some real-life code for the SNES. It's a small set of instructions that's supposed to color the screen completely green. This screen isn't green, I know that. :) But it's not too far off!

If you look at this output of bsnes, you can see what I was expecting to see:

But I did not write or invent this code, and if I load it in bsnes with accuracy mode, it looks like this:

And after a reset it looks like that:

So, I think it's safe to say that the pitch green image is a product of emulation errors because a more accurate emulation also shows a random image.

Going to test a sound sample next.

As I said, it's an interesting world where a picture like this can be considered success. :D
