Game Secrets:Sonic Gems Collection

Lost Sonic CD JP Soundtrack

It is possible to restore the JP Soundtrack to Sonic the Hedgehog CD in the EU Playstation 2 version of Sonic Gems Collection by editing the ISO in a hex editor.[1] Just open the ISO and search for BGM_US and scroll down to line 1353439A and replace the US with JP. After being saved the game will run the Japanese soundtrack.

Removed games

By using Pro Action Replay on the GameCube version of Sonic Gems Collection, it is possible to show the title graphics and name of games that were removed from the final version of the compilation, though the game data itself is missing. Two of these cut games, Monster World IV and Sonic Eraser, use an orange-red "MD" icon, likely to denote that they were Japanese-only release games. To display these games, use the code 021CCD5B 0000XXXX, where XXXX is substituted for the following:
