Another missing: Brian Lara Cricket (original, not '96), came out in Europe only, 1995. Also, the other one says "Brian Lara's Cricket '96", the apostrophe-S should be removed from the title.
Cannon Fodder was Europe only, no North American or Japanese release. It did come out here on other systems, but not Genesis.
Earth Defense came out in the US.
I think Mega Games 10 is a Brazil release, not Europe. Also, Mega Games 6 Vol. 3 (European release) is missing.
Shane Warne Cricket is misspelled, and I'm pretty sure it only came out in Australia, as Shane Warne is Australian.
Asterix and the Great Rescue certainly came out in North America, as I own an American copy (red Genesis stripe and all).
Tetris was Japan only, no European release, and it wasn't actually developed by Dr. Pepper or Pagaent Soft, that's just a fake credit inserted into the ROM that's out there. It was developed and published by Sega.
I don't believe Waterworld was actually released anywhere, and it only exists in a prototype.
