Re: gtBASIC

I managed to compile it, I got the gtBASIC.exe working (I tried to compile the invader.gbas file and it runs fine with the on-line emulator).

Re: Character Sets

I think there might be a pointer in page 0 to the character definition in which case I can create a rep...

First : the Picture option doesn't show a picture at a time: instead, the three images are smaller than the screen, overlapped (you can see the three images on the screen, sometimes more times every images... do you know the pictures of your son/daughter on your fridge?

Re: LCC for the Gigatron. Take two.
