There is a new revision of the PSP Slim motherboard, dubbed TA-085 v2, as opposed to TA-085. The newer motherboard revision only seems to have taken away the ability to create a Pandora battery, because it doesn't allow for battery EEPROM flashing. No other abilities have yet been discovered. It is unclear at this time, but the new motherboard revision began shipping with either firmware 3.72 or 3.73, as opposed to 3.60 of the original slim PSP version. There is a way of determining the motherboard version from the box by the location of the serial number. This only applies to North American units. If the serial number is on the bottom of the box, it would be the TA-085 motherboard. If the number is on the back of the box, it may be the newer TA-085 v2 motherboard.
