GCRebuilder GCRebuilder is required to install all patches for PSO GC. This useful tool allows you to extract individual files from your ISO, import individual files into your ISO, extract your entire ISO to a folder so that you can replace multiple files at once (even if the new files are bigger than the old ones), and build a new ISO from the folder where you extracted your original ISO.
These patches require you to extract a single file from your ISO (usually "PsoV3.dol"), patch it, then import it back into the ISO. These patches are compatible with Wii and Dolphin.
Full Word Select Patch This patch unlocks a previously hidden copy of the PSOv2 Word Select menu contained within PSO GC. Not only does the V2 menu fix the problem of not being able to access the "Reply/Confirmation" Word Select category when you're on Ragol, but it also allows you to use Word Selects from any category at any time.
Item Loss Prevention Patch This patch prevents you from losing your unequipped items and Meseta when you don't quit and save properly while playing online, which often happens as a result of the game crashing.
Ice Patch This patch increases the success rate cap of the Blizzard special in Ultimate mode from 20% to 60% and also improves Gibarta's casting speed and freezing rate. As a result, Blizzard weapons and Gibarta are finally useful.
Draw Distance Patch This patch allows you to see things from farther away by raising their clipping thresholds.
Offline Map Patch This patch gives offline Forest and Cave the same monster spawns as online mode, instead of the reduced enemy spawns they usually have.
Quest Music Patch This patch allows you to hear the correct music in Episode I Spaceship and Palace quests, such as Prospective Horizons.
Disc Music Patch This patch replaces the songs played by several of the music discs.
Ending Music Patch This patch replaces the online looping ending music with the unlooped ending music used during the game's credits in both episodes, which allows you to hear the lyrics to "Can Still See The Light" when you beat Dark Falz online.
These patches require you to extract your entire PSO GC ISO to a folder, replace multiple files within that folder, and then build a new ISO with the modified files. These patches are currently only compatible with Dolphin.
Episode III Lobby Patch This patch allows you to enjoy the Card Lobby from Episode III by replacing Lobby 12 with Card Lobby 1 and Lobby 13 with Card Lobby 2.
