Hi, I was looking for the M4 firmware source code on Duke’s Github but couldn’t find it. I know that when he stopped the project he open sourced the Gerber files, and there’s also the M4 ROM Z80 asm source on his Github. Does anyone know if he mentioned a specific reason for only providing the .BIN files for the STM firmware, or is it just a matter of asking him ? Or maybe it’s available somewhere and I missed it ? Thanks. ---

id also like the full source for emulation, and tweaking functionality…eg, adding TLS/SSL/HTTPS support ---

Yes same. I mean we could probably decompile it with AI, but Duke may also be happy to just release the source code for this as he did with the rest. ---

I second the idea of asking Duke
