This is a bundle of the wood dumping tools used to dump DS roms. Wifi and slot 2 aka GBA slot tools are available (DLDI capable rather than 3 in 1 or similar).
I swear like 99% of arcade games wouldn't even exist these days outside of MAME the arcade machines are old and busted very few ever saw any sort of home conversion
