Hey all,
Back again with the Kicad files for the Bung Game Doctor SF 7. These are verified accurate and functional. Enjoy.

awww, "2rd" is fixed lol (or at least my SF7 has that typo/misunderstanding on its PCB)

Re: Bung Game Doctor SF 7 Kicad Files
Amazing. I'm very interested in Game Doctor 7. Although it's device before 30 years ago but i like it.
I just implemented sending/receiving data from PC to Game Doctor 6/7 via parallel port.
The core chip (named "GDSF 701",160 pins) can clone ? have you tried?

Hi, that’s pretty cool, I hadn’t seen the pc communication software before.
I am capable of designing a clone board and writing the verilog necessary to replicate the GDSF7, but the fastest way to make that happen would be to reverse engineer the GDSF7 bios and document all address ranges it uses on the SNES and for what purpose, as well as any reads/writes it performs to enable/disable functions. With that info, it wouldn’t take long to clone the asic.
I am unfortunately not experienced at assembly code and the snes architecture, so I would need someone else to do that part

It was also very difficult for me.
I bought a non-working GDSF7 mainboard, less than $5, just need the ASIC. The rest parts use new, they are easy to buy and very cheap. Now i will try to recover this device according to the PCB you shared. I hope to witness the miracle.
Re: Bung Game Doctor SF 7 Kicad Files
Oh, yes, if you were able to take the asic from the non working board, and you get the rest of the components new, it will work! Assuming the asic isn’t broken. I have transplanted all components to my new pcb and it works perfectly.
