RetroPie 4.0 uses an output resolution independent render resolution of 640x480.

Open /home/pi/.reicast/emu.cfg to modify render resolution. BIN files under /home/pi/.reicast/, and will be automatically created the first time you run Reicast without VMU files. On occasion, these VMUs do not get formatted quite right during creation, and the Dreamcast can’t save or load data from them. They just need to be reformatted – run the SYSTEMMANAGER entry in the EmulationStation Dreamcast menu and / or see this post for details. BIN files under /home/pi/RetroPie/BIOS/dc/, and will be automatically created the first time you run lr-flycast. There is an option for the core to enable per-game VMU’s. This option is recommended if you have several games or a game that takes a large amount of space.

ManagementĪ Dreamcast soft-reset (A+B+X+Y+Start buttons at the same time) at the ROM’s title screen will also take you into the Dreamcast BIOS to manage the VMU’s.

After formatting VMU’s, exit the emulator and restart if using Reicast.
