GENESIS PLUS (Sega Megadrive/Genesis) to port GENESIS PLUS Charlsa MacDonalda, który jest w miarę znany dzięki wersji dla Wii (GENESIS PLUS DX), teraz dzięki osobie o nicku Eke-eke, znów możemy go zagościć pod PeCetem:). W chwili obecnej G+ SDL jest opublikowany w bardzo podstawowej wersji, nie ma frontendu tak rozbudowanego jak wersji WII (mówiąc wprost w ogóle nie ma frontendu;)) i potrafi nagle się poddać i zawieśić. Oj, przyjdzie nam jeszcze poczekać aż ten port nabierze rumieńców.
