i aint learned enough to fully understand what’s going on here, but a lotta peeps are cracking open their xbox’s and gameboys to make use of the impressive processors within. pretty much anything can be done using a gb to run whatever you attach it to. there’s a site selling addons so you can launch rockets into orbit or make a silly little buggy with lego parts.
well i know for like 130usd, you can get a gba flasher that holds 512mb. thats enough for a dozen gba games plus some mp3s or video files. this also includes the proper usb interface.
you can also use the gba as an emulator for nes,snes genesis etc….
