Just a Quick Question. Can Ya Help?
 

Ok, I own a Playstation, and was thinking about getting a mod chip installed in it. But i heard of swaping the disc? what do i ned to do this swaping method?

Do i need to still buy something? or can i do this swaping thing without buying anything?

Please tell me every detail there is to this other method of playing a back up.

You could only use the swap trick with the very first Psx, you still need the chip a game enhancer or the New pressed boot disk 4 the Psx1, so yes you still need to get either 1 of these 3 to make it actually work.

You can use the swap trick for any Psx, but eventely, your motor breaks, a new one cost 30$
