Well, I've been working on this tool for a couple days, if that. Total time though, maybe a couple hours at most. It's basically a tool that converts Z80 GameBoy ASM (Note it's very important regular Z80 doesn't get confused with the GameBoy's version of it) into compilable C# code. This is useful for ripping game code, such as a loading procedure, or getting a better understanding of how things work. Here's what it looks like.

Getting somewhere. Probably won't follow through with it though.
