I agree. It´s been a very long time since I used to be active, and it is indeed sad to see that this site, who used to be filled with MANY artists and friends filled with great ideas and personalities, is no longer being used by that many people. We need to do something in order to save this site! I really do not know what exactly can I do, but if I can help in any way, I will try to do my best. :)
Sonic:go on custom stages and put a ramp and a few blocks before it so sonic can run before the ramp put 7 spikes and put another ramp also put a enemy in the other ramp finally run and in the ramp press
B+↓ then sonic will go in horizontal direction exactly to the enemy (heres a second glitch)when sonic hits the enemy it automaticaly appears above.
Wario: do the same stage as in the sonic glitch then run and press B+→ and wario motorcycle will bounce in spikes.
There are also youtube videos of each glitch the sonic glitch video is sonic is the glitchiest character and i dont remember the wario video name.
