Yes. A GBA release of the first Sonic game, which Sega felt the need to completely recode for the GBA rather than simply port Sonic 1 to the GBA.
Sonic Rush Adventure was a far better game than Sonic Rush, though I feel it wasn't up to the level that Sonic Advance 2 and Sonic Advance had set.
And I disagree. Sonic 1 with spindash is actually pretty fun. But it has to be coded competently so it doesn't glitch the collision detection. Sonic Megamix and Sonic Jam did this right. Sonic Genesis did this very, very wrong.
Michael: Jodie, how's my schedule look for today? Jodie: You've got a conference and dinner party at the Japanese Embassy regarding wildlife protection. Michael: Oh, yeah...sorry, but I'll have to cancel that. I'm heading out to save America!
