Space Station Silicon Valley (fixed), Banjo Kazooie/Tooie, Donkey Kong 64, Super Mario RPG, Super Mario All-Stars+Super Mario World, F-Zero X DD, Diddy Kong Racing, Dreamcast Sonic Adventure 1+2 plus Sonic Advance capability, Kirby Super Star, Sonic 3D Blast (Saturn), Sonic and Knuckles, and more.
I will update this.
(SSSV is also known as "Evo's Space Adventures" for the PS1)
Too many to list. Anything from Square would open the flood gates to more of their games. Currently they plan on releasing the last Square made game for the SNES, Treasure Hunter G later. It's an import, and a must for any Square fan. Ironic they choose the last game made, first for VC.
Chrono Trigger. My all time favourite RPG that never came out in Australia on the SNES, it eventually came out here on the Playstation but I didn't have one so here's hoping it eventaully comes out on the VC.
Chrono Trigger
Castlevania: Rondo of Blood
Earthbound
Monster World IV
Zombies Ate My Neighbours
Shining Force II
Soleil / Crusader of Centy
Super Mario World 2: Yoshi's Island
Ys Book I & II
Ys III
Secret of Mana
Seiken Densetsu 3 (with English translation)
I heard that they won't be able to make Diddy Kong Racing and Banjo Kazooie because the game designers were bought by microsoft. Those are def. my big 2.
