Not to be confused with the n64freak GBA board I did previously: https://www.youtube.com/watch?v=55pGYc6LDEQ
This is a brand new design intended to be a drop in replacement for the original GBA system board. You will need to salvage a working CPU and SRAM from any model GBA (note that SP CPUs will not work), 32 or 40 pin is irrelevant, and then you should be good to go with any screen that supports 32 pin GBAs (does not support 40 pin screens, even if the CPU came from a 40 pin donor). 

The supporting circuitry has been redesigned to address a lot of the flaws with the design of the original circuit and to support modern power handling and audio amplifiers but time will tell how the design ages. 

Unlike the n64freak boards, these do come pre-populated with most parts, however, including full aftermarket replacements for nearly every component (amp, cart connector, power management, link port, etc) and new old stock parts for everything else (power switch, L and R buttons). 

Sleep may be triggered with the A+B+Select button combo and should work for every single game, including previously unsupported titles. 

RGB may be triggered by holding A and B for 2+ seconds.
