hi! Basically I secured the roms through a MAME full non-merged set that I had from a couple months. I had to parse through the set, by making a playlist. Basically used a tutorial for all this..
Then I found the necessary bios, and put that into the dc folder of the systmes folder in the retroarch emulator folder found in the launchbox emulator.
Naomi was a little more complicated, but basically the same thing.. I still cant get the initial D games working. If anyone has any ideas, greatly appreciated!!!
Cheers!!!
