I should probably port my TI-89 Basic game Maze Runner to ASM (using TIGCC and writing it in C)...but the problem is that I'm not sure how best to port the other programs it requires. Mapper should be pretty simple to port; so should MultiMap (since it's nothing more than an extender for Mapper); the problem program is Grid Picker, since it relies on variable-size and dynamically-created pictures. I obviously can't use sprites for this, so how on earth do I make a picture in C whose size is determined by arguments passed to the function?

When you declare the dimensions for the array containing the sprite, use *argptr.

I know I'd need to use argptr for arguments to the program itself - this will be an internal function, though - so it doesn't need argptr. What I want to know is, is it possible to create a bitmap (using the bitmap routines in TIGCC) that has a size that is not known at compile time?

arguments

I meant *variable* arguments. Not clear enough, obviously. The arguments can be defined during execution.

Other possible answer;
no I don't program games

Not just games are featured. For example, see link.

Sounds like a personal problem.
