oh ok, sounds interesting! i know the modchip is the quickest way to play NTSC/COPY/MULTI-REGION etc... but to get a modchip the ps2 needs to be opened, which cuts the warranty sticker on the back, and when you go to sell/trade your ps2 to Stores, (EBGames i know for a fact) wont buy it.
The HDD and Network thingy is a good way, but i think it wouldve been to expencive for HDD and netwrok thingy, then if your not very computer literate it may be hard to network games to the HDD. abit too complicate for myself.
this new thingy you speak of sounds ok, all depends on price though. i still think modchip is the quickest way to play everything (within reason) on your ps2. and if you can modchip the ps2 yourself, then dayum... that was a cheap modification! modchips dont cost that much, i think between $10 and $30
