|- - - coding for the gameboy - - -|
Some time ago I tried to program for the GameBoy. Tho I managed to make a working tic-tac-toe game, it only worked on the GameBoy Color. This time I want to make an original game that works on the original Gameboy.
While I prepared the project files, I started thinking what type of game I wanted to make. I wanted to make an original game, but all I could think of was making ports. First I considered to port "Stay Frosty" for the Atari 2600, but after considering the prite limitations I was going to have to overcome I decided on porting X16-Maze for the Commander X16 instead.
I started making adjustments to my way of programming in assembly. I used to write everything in a single file, and to repeat a lot of functionality. I had to learn how to use multiple files for a single project, as well as to implement calls to functions I had to design. Aside from the ease that comes from being able to sepparate the project in files and folders, I could also work with text without many complications. All of the on-screen text is converted from ASCII to my custom font tiles (the font is based on Castlevania 3's one). The custom copy routine also allows for new line characters, so it doesn't have to copy each line individually.
I hope to continue with this project untill at least I've got a playable game. If you're interested in following the project, here's the github repo.
