A friend of mine got married a while ago and since I wanted to give them something special as a wedding present I decided to code a game boy game starring him and his wife.
This was my first game boy game and I coded it in C using gbdk. I did the sprites in grafx2 and used tiled for doing maps (using a simple exporter plug in i wrote). Next time I’ll probably code the game in ASM instead but since this one was really simple I didn’t have any problems with performance.
I bought a usb cartridge from kitch-bent, loaded it with the game and gave it to them together with a game boy color (I know, a DMG would have been way cooler).
