I has tested the v1 and v2 beta of Sonic 3D Blast DX on an ATGames Ultimate Portable Game Player and can confirm that It crashes on the Green Groove Knuckles Special Stage. After I give Knuckles the 50 rings, it makes the fade sound then flashes white briefly like normal and then just a black screen.

I have tried both Act 1 and Act 2 Knuckles, and could not reproduce this glitch. This bug may be caused by your ATGames Portable, which may be flawed in mimicking an authentic Genesis system.
