Homebrew:Multi-Cart Menu
From veswiki
Democart 2 was hacked by Sean Riddle into a menu for the Multi-Cart. This was initially made using a hexeditor chaning the op-codes directly rather than disassembly and re-compilation. Later with tools becoming available it was disassembled and more changes could easily be added. The first release version contained several Easter Eggs which also used the LED that the SABA 20 cartridge has, clue in the Multi-Cart binary file is "I like pie".
Later additions was made by e5frog as more games were added to the cartridge.
