Which chip do I choose?

The real question here Cyber is, are you ever going to make up your mind and get that damn thing modded? You have been asking this question and contemplating doing this for a very very long time and have still yet to go through with it. Your almost ad bad a Seany with his xbox about a year ago.

The Infinity is a great chip, you will be able to use it with your Official Sony HDD. No chip by its self will let you play back-ups online. To do that you will need to patch your back-ups with the DNAS patches. Yes the Infinity will output the correct signal when playing a PAL game on an NTSC system. The only chips that support mod protected games on a PS2 are the infinity and DMS3 and DMS3+, but only on v9/v10 consoles.

Just make up your mind and get on with it! You have had that v4 since the way back when and its still un-modded. You will be lucky if it even reads recordable media. But if its been gently used over all these years you might be lucky.
