PSGroove Can Be Ported To All (Earlier) PS3 Firmware Versions

While I was on the move, RichDevX tweeted the following: “awesome! I successfully executed lv2 privileged code on a ps3 debugging station.”
Which RichDevX later put into layman’s terms: “…it means that I’m able to port psgroove to all PS3 FW versions (debug/retail (pre 3.42)).”
That’s pretty sweet — especially if you’re still at firmware 3.15 for OtherOS reasons.
