Sylverant PSO Patcher

icon The Sylverant PSO Patcher is a boot disk which enables anyone with an original Dreamcast version of Phantasy Star Online to play the game on private servers without the need for any separate application codes. The patcher also adds support for online play with versions of PSO that did not work on private servers in the past.

Created by Lawrence Sebald (aka BlueCrab), the Sylverant PSO Patcher also acts as an import boot disk for various Dreamcast games, when using a game other than Phantasy Star Online just ignore the onscreen warning that the game is not recognized and continue as normal.
NOTE: The Sylverant PSO Patcher is created with the independent development kit KallistiOS and following the wishes of the original developer of KOS (Dan Potter), the application will only work with original games on GD-ROM.
