    Snes to 3DO adaptor

    This is a collection of files posted on Atariage by user River Patroller aka Sebastian. Since the links on the original post are not working anymore I collected all the files and added this small description.

    The goal of this project is to interface a Snes controller to a 3DO

    I claim no credit for this works

    possibly there is no intrest in resurecting such old thread, but since i've already put 3 days of my time into this, maybe it would be good for someone somewhere if i shared the results

    i've developed simple SNES to 3DO adaptor, currently supporting only one controller - its not that its complicated when you've basics covered, but i would like to get some feedback or buttons mappings first

    so here we go

    schematics - (warining - do not mount R1 and R2, add crystal to pins #4 and #5 of MCU)

    board layout - easy enough to do at home with modest setup

    assembly drawings

    HEX file for programming AVR - please set CLKDIV8 to disabled and CLKSEL so it would use crystal over 8mhz (1110 it was)

    this board was designed to fit inside KM-100B case by maszczyk

    pins for SNES ports were taken from split DB25 male plug as i couldn't find any supplier for these sockets locally
