| 0x01 || No || Set minimal "Y2" drawing area. This setting overrides what game set in GP0(E4h) command (Set Drawing Area bottom Y2 coordinate). Setting is used only when given value is lower than what game originally sends. In simple words, this work as a crop for the bottom of drawing area. ''Warning! This setting can have bad effect when copied straight from PAL to NTSC game and vice versa.'' | | 0x01 || No || Set minimal "Y2" drawing area.

| 0x04 || Yes || This config is multi-command for cdrom behavior. Value is bitfield, but not usual one. This config default value is 0xFFFFFFFF, to "enable" bits we need to really disable them. Windows programmer mode calculator in dword mode should shed some light here. To see enabled bits just use NOT operator. Vita use 3 additional (10/11/12) bits not available on PSP. | | 0x04 || Yes || This config is multi-command for cdrom behavior. Value is bitfield, but not usual one.
