- The Satiator, that plugs into the video card slot so you can still use original CDs.
- The Saroo, that plugs into the cartridge slot, also emulates the RAM expansion carts, and it is much cheaper (but seems to have some compatibility problems).
Good to know. Both my Saturn and Dreamcast's optical disk drives have packed up, so I've been wondering what to do with them. The Saroo looks less invasive than the Satiator, and would leave me able to play my old games if I ever get the optical drives working. But since the Saroo blocks up the RAM expansion slot, does it also include that RAM for games that need it?
