It is compatible with the 64-bit processors

It was replaced by Dreamcast OS.

System requirements
Released for PC, but not the Sega Saturn without the Computer Pack cartridge for Sega Saturn, which does not update from SegaOS 95 for lack of ram (2MB), it is recommended at least 64MB RAM, 32MB RAM works but it freezes at startup and applications, the SegaOS 97 can work at less 128MB RAM for run Sega Dreamcast games and programs (For run Dreamcast OS programs and games, it requires system upgrades), I is also recommended to use CD-ROM for games and programs as there is no digital distribution of software until the OSR 2 major update or without SegaNet Marketplace. It is also recommended to use a 32-bit processor of 100MHz or better, it is also 64-bit compatible.
