README
DMG-A02/README.mdDMG-A02
This board is a repair board based on the DMG-A02-10. The DMG-A02 is used by german versions of Pokemon Red/Blue, as well as Pokemon Yellow, Pokemon Trading Card Game, and Link's Awakening DX.
The original featured cut holes that were used for debugging purposes, most of these have been omitted.
This board was designed to closely replicate the footprints and routes used by the original cartridge board. All components may be sourced from an original cart.
