Analog values only go up to 254 when software rescaling is on

[vladone97]

The normal range of analog values is from 0 to 255, but when software rescaling is on, the analogs can only go from 0 to 254 (checked in Vita Hardware Test). It may not seem like much, but some games are programmed to detect that 255 value. For example, Killzone: Mercenary only turns the camera to the right at full speed when the right analog reaches 255 on the x axis. Any less and it only turns to the right at half speed.
