I hope I'm not imposing but I'm having a few problems and thought one of you might be able to help.
I'm trying to figure out the cartridge connector on the Wonderswan console. It's going ok, but I need to verify my findings. Unfortunately, most of the chips used in the carts are either Bandai customs or too difficult to find.
I don't have an exact number handy but a common example is:
I can't find the manufacturer and hence, can't find a datasheet. Does anyone have any suggestions on how I can go about finding the pin-outs? From those I can trace it back to the cartridge connector. I know which ones are connected to GND or Vcc, and have a rough idea of which ones are address lines and which ones are data - but I need specifics.
Sorry for the waffle :) , but if someone could help or point me in the right direction I'd be really grateful.
