well, this thing has proven surprisingly useful in debugging things. Apperently the META makes a GMV of any image you try to load into a program from the SD card, or any bitmap at all, I don't know which.

... I still have no idea why my spaceship (white dots on black background) is invisible in the GMV, but at least I know that's what the issue is, so thanks for that.

But looks like the full res mode isn't supported yet ?

Yeah, currently it assumes a resolution of 80x64

EDIT: aaaaaand support for that is added

Nice, this tool is a must ! :)
