What it does
redream is a Dreamcast emulator offering desktop and Android downloads, save states, cover art and high-definition display options.
Use the compatibility list before deciding how to play a particular game. The project says its setup does not need external BIOS or flash files, which distinguishes it from emulators with those requirements. High-definition rendering and other edition-specific features still need checking against the download you choose.
Use Library > Add Directory to point redream at your game images. Its help page supports GDI, BIN/CUE and CHD, and discourages altered CDI images. The built-in replacement BIOS is enough for ordinary setup, but it omits the original boot animation and audio-CD player. Controller mappings can be changed in Input.
