Hello Copper,
I think its great

that you are making this Mr.Do and Mr.Do Run Run emulator. I remember these games from the arcades when I was very young

My Hardware: DS Lite + SuperCard Lite Rumble + Passme Card + 1 GB micro SD card.
.
Now to the game test -
1 Downloaded and unzipped ok
2 DLDIrc 'ed the mrdo.nds
3 Copied to the DS lite
4 And it run the initial screen where you can select the difficulty levels.
I can use 'B' to zoom the background images,
I can use the D-Pad to scroll left and right to select the different games.
The sound is working.
Problem
The 'A' button is not working so I cant actually start a game

Let me know if you have a solution. Thanks
