About that there UP mod chip.

Ok I watches as Im sure many others have, the video where the guy downgrades 2.81 to 2.71 with the mod chip. I also have been able to find the epsilon BIOS and was wondering. Is it possible to downgrade using the BIOS without having the mod chip? Or is it possible to apply whatever the mod chip does to the psp without the chip itself?

i dont think so because if you could everyone would know about it.

No you have to have the modchip

No because the UP adds extra Rom etc whihc holds epsilon bios. Even if the PSP had enuff to fit it on there wouldnt really be a way to get it on.

Na, then everyone would have done it by now.

thats what i thought
