I wanted to send in this game/demo which I made about two years ago.
It's one of my first attempts to create a platformer on the GBA. I used the graphics from the pc version of Bernard & Hank. You play with the character Bernard, he can shoot, jump and walk a little on the map. It was the start of a GBA version from our platformer. But I couldn't get the character picking up coins without error.
I didn't include the source code. Because I don't want the graphics ending up somewhere on the net.
However, source code is available upon request.
