As promised, Dark_AleX has released the Firmware 3.11 POPS PRX to be used in Firmware 3.10 OE. Dark_AleX previously mentioned that he will not be creating Firmware 3.11 OE since the only change between 3.10 and 3.11 was the POPS PRX. So, thanks to DAX, you can now use the Firmware 3.11 POPS PRX in Firmware 3.10 OE so you can enjoy better PlayStation 1 compatibility. This plugin allows you to run all PSX game from firmware 3.00 to 3.11. This PRX does not need flashing and instead runs as a plugin so it can be enabled/disabled as required. See the readme file for instructions.
