Sonic Gems Collection for GameCube was released on August 16, 2005 in North America. It was then re-released in 1996 as a Player's Choice edition with the same game ID.
The Japanese version features the entire "Bare Knuckle" (known as "Streets of Rage
" in North America) trilogy for the Genesis as a bonus. In this export version, these were removed so that the ESRB rating could be lowered. The Japanese version also included "Bonanza Bros.
" for the Genesis, but that was removed from this export version as well.
Tails' Skypatrol for the Game Gear was originally released exclusively in Japan.
