A WIP reverse engineering of the Leapster2's SDMenu.
This requires AN ANCIENT version of arc-elf32-gcc to compile, you can get it here: https://www.maintech.de/en/support/toolchains/
Mirror of said ancient version: https://archive.org/details/usr_20230518
Please note that a byte to byte accurate decomp will most likely never happen as LeapFrog's compiler they used for the Leapster2 hasn't released in any form yet.
