Quick Question
 

Any way you cant back up a ps1 game and play it on a ps1 that is NOT chipped

google for psx swap trick that should come up with something

discs spins fast, slows, swap, spins fast, slows, swap, screen turns black, swap.

how can you swap the disc when it stops turning when you open the (how do you english say?) the top of the bin. you know when you push "open drive "button something goes up and only then u can reach the disk.

Anyway when its open the cd stops turning

oh: and what about that http://www.megagames.com/psx/psx_utils_bootcd.shtml
PS-One BootDisk - CDRWIN [57 KB]
does that work instead of an modchip?

AFAIK the Swap-Trick works with a little spring, so the PSX don't recognize that it is open.

spring, summer ,atumn, winter.

and it only works in spring???

or do you mean this:

is there any installation tutorial for that one on PSOne or do i just have to stick it in the place where the lid usually closes?

quick answer: NO :D

Why dont you just purchase a PS-X-Change .

why is there no free open source ps-xchange?

No, There is no working boot disc that is Freeware.

i always knew open-source community is damn lame :D
