Mathieulh and Dark_AleX have confirmed that work on custom firmware 3.80 M33 has already commenced. There is no set release date at this time, but expect to see a release in the near future.
While working on 3.80 M33, the two found a peculiar string in the IPL’s payload file — pspbtcnf_03g.bin. What does this mean? Well, flashback to a few months ago when a string referring to pspbtcnf_02g.bin was found in firmware 2.71. Once the PSP Slim was finally released, it was discovered that “02g” was none other than a codename for the slim hardware.
Could “03g” be the codename for a third PSP hardware revision? Perhaps for the rumored PSP phone? It’s possible.
