Dragao has a Sonic Cartridge that had some invalid instructions that would cause the game to crash at a certain point. The solution wasn’t to find a replacement game at the local flea market, he Resurrected the Sega Cartridges using some old Computer Chips. The game was originally loaded on 16 bit memory chips, not having any of these handy from the donor computer motherboards he piggy backed 2Â 8 bit memory chips to make it work. An Arduino was then used to blast the code onto the new chips.
