Hi,
think I have a DKJr pcb which runs DK3. I don´t like both games.Want to convert it to Donkey Kong.Read a lot in old threads but it doesn´t help me.Does anyone have an instruction ? On my pcb I found proms on the CPU board located at 2E 2F and 4E. EPROMs are at 5A 5B 5C 5E and 3H. On video board: prom at 2N, EPROMs at 3N 3P and 7C 7D 7E 7F.
Now which set of ROMs and PROMs to use ?

Thanks for help.

Hi,
here two pics.
Looks like a DKjr pcb upgraded to DK3. The video pcb seems to be "normal". The cpu board is wild wired with piggy pack eprom, ram and one logic ttl. Above the piggypack eprom at location 4e is the 7051 prom who gives me questions.
Noone an idea which roms/proms to take for downgrade to DonkeyKong ?
Thanks for hints

Neat conversion...wouldn't mind having one like that myself...it'd go good with my Radarscope board hacked to run DK Jr :D I've never heard of someone downgrading a DK Jr board to DK, although I suppose it's possible, since a Double Donkey Kong runs on a DK Jr board. Even if you can do it, you're not gonna have all the right sounds, since some are generated using logic on the board, so it'll have some DK Jr sounds (running, jumping, etc)
