SEGA has once again been the target of tech-savvy fans, as some disassembling of the official Sonic & SEGA All-Stars Racing flash site has revealed unannounced information, including the presence of the Bonanza Bros. and Opa-Opa (from Fantasy Zone) as playable characters.

The find came from fan blog TSSZ, with writer Ryan Bloom publishing a wealth of images that pertain to characters and All-Star moves. The snapshot above is apparently taken from the Characters page from the official website (which in itself is a replication of the game’s actual character select screen). Behind recently-confirmed Akira from Virtua Fighter is a tuft of blonde hair, leading the blog to suspect that companion fighter Jacky could be racing with him.

More obvious is an image of the Bonanza Bros. next to Big the Cat, and a silhouette of Opa-Opa. Exploring the “Moves” files uncovers a Kapu-Kapu from Chu Chu Rocket!, the ‘PARTS SHOP’ balloon from Fantasy Zone and the blimp from Bonanza Bros. It is assumed that these are clues to All-Star Moves, which if proven correct leads to the presence of the Chu Chu Rocket! playable vehicle as well.

Quite how SEGA will react to its website being torn apart remains to be seen, but it wouldn’t be the first time eager fans have been impatient to find every last morsel of detail about one of its games. We’ll bring you word of any comment from SEGA about the find.
