Can't find the old thread, so I'm posting a new one instead.
Anyways, new MGS game came out, and I'm looking into buying myself a new PSP (after E3 if nothing new gets announced), and from what I came across, apparently Datel has found a way to load their own hombrew software (Action Replay) that works across all PSP models and up to firmware 6.20 (the latest).
Hard to find information regarding this (other than a couple youtube clips), but does anyone know if there's been a downgrader made yet or possibly CFW for 6.20? I never used my old PSP much for pirating psp games, but more-or-less handheld NES/SNES emulaton as well as raping the load times on the UMD titles I own.
(Both GTA Stories sucked without near instant loading from mem. card and 333mhz CPU for super smooth framerate)
[EDIT] Seems like two coders in the scene has made a "Half Byte Loader" for homebrew on 6.20, I guess I'll start googling some info on that. If I can at least have my SNES on-the-go I'll be happy.
