what chip to use

[convict]

what is a easy and good chip for the psx2?

easy AND good doesn't work well together.
either you get an easy chip, like the neo.. but it sucks. it won't do imports, only cdrs dvd-r, and you need to swap, and depending on your board revision, patch some games too (dvd-r won't work on these either).

or you get a good chip, like the origa.. it plays imports without swap, cdr and dvd-r copies with a single swap, but the installation is hard to do and requires professional equipment and a very steady hand.
