Things are going well. Have added some features to the software side and also got some stuff working hardware wise.
Can confirm that US/JAP roms are working.Only tested EU roms before. Used my japanese Nintendo junior and a japanese CIC to confirm that the snesram is working with that setup too.
Max and i added an bootloader to the AVR software toolchain. Now its possible to flash the AVR firmware via the same USB cable as for the normal bulk transfer. So no extra ISP programmer is needed to change the AVR firmware. This is super fast, can flash the 16kb client side firmware in like 3 secs.
Added a reset line trigger to the snes bus. Now the client software can reset the snes after uploading the software. So its possbile to push a rom via ucon64 from the pc and then reset is done by ucon64 and the firmware. No interaction needed from there.
Max is refactoring the schematics so that we can send them over to the pcb fab soon. Stay tuned.
