Could be a power issue. Had a Gamecube in the same situation (DOL-001). Replaced all the caps from the power board (the one that`s under the mainboard) and changed the modchip to feed from 5v.
After that, the adapter worked. Also i inverted D0 and DI points
Strange i'm playing right now Street Fighter 30th anniversary normally. To the user that tried it: try redumping your cartridge or redownloading your backup.
