I have a RP2-B and I used BerryBoot on a 16GB card to install Rasberian, RetroPie and Openelec. I get into Retropie ok, I’ve set up my controller and can get around all of the menu’s. I’ve transferred ROM’s and can see them on the RP, yet I’m not sure how to launch them?
From the left/right scroll, I have RetroPie, ScummVM, Apple, DOS, etc. When I go into RetroPie, I see all of the config items like Setup Wifi, Configure Audio, but for the life of me I can’t figure out how to see my list of games.
Also, on a side issue, I have seen a lot of tutorials that say I want to select the option to “Expand Filesystem.” Since I have 3 different OS’s on 1 card, should I skip that?
