Re: dd and Playstation CDs
I have a 3yr old who LOVES cds. He has destroyed more cds than I have
and I have a hobby of getting AOL giveaways and nuking them... They make
great coasters and frisbees.
At any rate, you can get what's known as a "modchip" so you can backup
your own games (keep the originals in a safe or such location) and play
the backups. Gettting the chip is easy, but installing it can be very
hard as you can destroy your PSX if you're not careful. I had to find
someone who could install it for me.
