Game Gear titles in Sonic Adventure DX (Steam) #84

Open olddesklamp opened 1 year ago

olddesklamp commented 1 year ago

In the GameCube and 2004 PC releases of Sonic Adventure DX, all 12 Sonic titles released on the Sega Game Gear were unlockable extras. In the current Steam/Xbox releases, they're inaccessible in-game but still present in the game's files in the /system/ folder compressed as .PRS archives.

I was able to extract them using a decompressor written by Nemesis on Sega Retro for Windows, but apparently everyone's favorite Game Extraction Toolbox can work too, though I haven't tested it.

After extracting the games using Nemesis' PRS decompressor, the ROMs will be stored as .bin files. These have to be renamed to .gg for them to work on most emulators.

Followed this tutorial just the other day: https://legal-roms.fandom.com/wiki/List_of_Game_Gear_ROMs#Sonic_Adventure_DX

Can confirm that it works.
