Hey there retrocoding friends. Indirectly prodded by @pervognsen I decided to dig out my old GBA stuff and then try to put together a quick "platform guide" for my blog: a round up of resources and resource hubs, along with just enough information to get bare-metal dev off the ground and clear away any toolchain nonsense.
Here's what I have so far, but I bet there are some GBA devs out there who can help me expand it. Any takers?
