Hey guys good news i found a way to play the Bugs Bunny - Lost in Time in psp.
Thanks GTA93 who minds me this idea again.
Anyway he tried the EUR M6 version and i too.I noticed that it works with many special keys but is is soooooooo slow.
So I tried another version which is the Bugs Bunny - Lost in Time [U] [SLUS-00838] and i get it.
It worked with the SLPS-01156 with the 5.00 popsloader in 3.52,3.71,3.90.
Lol i am happy for this.
