The software is coming down smoothly. Ported the usb uploader code to ucon64. Also Hirom support ist working now with ucon64 autodedection. So the Snesram board is becoming quite handy for daily dev work.
This hardware revision has 2 bugs which doesn’t make it possible to print pcbs now. There is additional OR gate needed to drive the CS line properly and an AVR reset switch is missing too. I guess when Max is back from his holiday he wants to fix this in the pcb layout. I think it would be smart to only use 4 sram chips and to have 2mb and not 4mb. Just to reduce the cost and get some more space on the pcb. If there is an interest from the community to support this hardware revision we gonna print some pcbs and sell them. Otherwise we gonna start working on a enhanced version soon.
