CFW/homebrew with support for PS2 gaming on BC PS3s?
I've got a Fully backwards compatible (GS+EE) 20GB 1st gen PS3 with firmware 2.80, I pretty much only use this PS3 for playing my original PS2 games upscaled on my HDTV (I've got another 40GB PS3 for online and regular PS3 gaming).
Anyway, since I don't care about online features for this console and it has a very old firmware that I assume can easily be modded, I was wondering if I'm missing out on any cool features CFW/homebrew applications offer, specially related to PS2 gaming (bypassing regions, extra upscaling options..etc).
Any suggestions/ideas would be great.
ps: Is a special USB still required to jailbreak PS3s?
