Cave Story is one of my favorite Indie Games. When I bought my Gp2x, Cave Story was one of the first games I downloaded for it. I immediately introduced it to my son so that I could share the sweetness of this game.
I am going to show an example of writing a cross-plaform game for GP2X/GP2X F-200 and Windows Mobile. I’ll test it out on a GP2X F-200, Palm Treo 750W and AT&T 8125 smartphone. It will also be playable on Windows and Linux, too.
