Nebie needs help - please

[kirbinster]

My son just got a PS2 and I would like him to be able to play backups. I understand there are differences between chips and what you have to do as far as swap or no-swap, but that is about it. The unit label says SCPH-30001-R with a date code of 1C - what version is this? I would like something that installs as a external cartridge or internal without soldering.

What limitations do I have once I alter the unit? What card do you experts suggest and what would it cost.

Thanks!
