Hey guys, I'm new to hacking but interested in hacking gen 1 & 2 games. Problem is, I have a Mac and it seems like a lot of the tools that are available for PC aren't available for Mac. Any suggestions on tools to use?
Hacking gen 1 and 2 can actually be easier on a Mac than on windows. I highly recommend using the pokered or pokecrystal disassemblies rather than hex editing, as miksy suggested. Although, if you're just learning the basics of gameboy programming, hex editing is a grey way to learn those skills (pointers, asm, data structures, etc. )
You should also use the gameboy emulator called BGB. It is a windows program, but you can still run it using Wine, which is a windows emulator for Mac.
I hack with a Mac, too, by the way!
If you need help with setting up the disassmblly, there are several people over at the Skeetendo forums who would love to help you out. Check out the IRC channel.
Anyway, like miksy said, there aren't many tools for gen 1 and 2. However, when you see te disassembly project(s), you'll see that the only tool you might need is a map editor.
