I previously asked this question on the LOWREZJAM’s Community page, but…
I’d like to know if I can make a game that conforms to the 64x64 limitation and runs on the Game Boy Advance.
I had actually thought about this too haha.
I think when it comes to the technical side of things it might be a bit interesting. The GBA screen is 240x160, so you kind of have a few ways you could approach it…
Bonus: You could also look at scaling assets 3x, cropping to 192x160 (for a ‘virtual’ resolution of ~64x53) if you are will to lose a little height to get more actual device screen real estate.
I decided to use a resolution of 64x64, by rendering everything to 3 64x64 sprites (that I will call the “display sprites”) and scaling them 2x; there are 3 “display sprites” on top of each other, so there are 3 layers, and virtual sprites (like the player) have to be rendered directly to one of the three layers, like background elements.
