After some 3.5 hours of work, I’ve at least got the core running..
For some reason I decided to really limit myself technically. The screen is 160 x 120 pixels, and the only available graphics is drawing four color 8×8 pixels sprites. Each color index can be one of 240 different colors in each sprite, and the sprites can be flipped along the x and/or the y axis.

The idea is to make sort of a 2d Minecraft or a harvest moon clone, where you wake up on some shore and have to do the best you can with the tools you find on the island.

GAH. THIS LOOKS JUST LIKE MY GAME.
GET OUTTA MAH HEAD.
Also… TESTING IN IT
Sounding awesome.
Looking good!
For some reason, I was so entertained by watching you make the font tileset. Graphically reminds me of Gameboy Color. Looking great!
now add the kittens
Y’know, if you coded this in Game Boy assembler, you wouldn’t have to worry about the underlying “looks like a Game Boy Color” framework.
Trust me, I did something like that but with the Sega Master System. Although the main difference was that I made a half-baked semi-emulation of the actual hardware with the actual register values, et cetera et cetera.
By the way, do you have any intention of emulating the 10 8x(8|16) sprites per scanline limit of the original Game Boy?
