Double Slot
One of the main features of the DS is the ability to detect GBA games that are connected in slot 2, and give bonus features for the adequate matches.
There are 7 GBA SRW games that are compatible with this feature: SRW-A, SRW-R, SRW-D, SRW-J, SRW-OG, SRW-OG2 and Famicom Mini Dai-2ji-SRW, a limited edition port of Famicom's Dai-2ji-SRW game. Each of these games offer a different amount of bonus cash and a special item. The English version of the OG games is said to NOT work with this feature.
