[TOMT][2000s][Website][Game?] Website of Fake Sonic Game

-it was a website that was promoting a fake sonic game, i remember seeing it in the 2000s

-the "game" featured on the site used Sprites from the Sonic games developed by THQ on the Gameboy Advance (i.e. Sprites from the Sonic Advance Trilogy and Sonic Battle)

-the website featured a very long list of "playable characters", and every single one of them (or at the very least, most of them?) had a super transformation

-the website featured like 3 to 4 screenshots of the "game" showing 4 players at the same time. (i remember one of the screenshots featured one of the characters in a super transformation flying/hovering to the right)

-i believe the "game" looked like a 2D platformer, but i think used HUD elements from sonic battle?

-i do not believe the game was called "Sonic Advance 4" or "Sonic Battle 2" but i could be mistaken. (ive tried googling those names but i get other fangames or concepts but not this website i remember.

-there is the possibility this site couldve been for a M.U.G.E.N. Mod or just a collection of Sonic Sprites in the style of the Advance/Battle games, as M.U.G.E.N. mods and sonic sprite fight videos were very common in the 2000s, but i very distinctly remember this being a sonic-specific "game".
