papel is wrong
Some translation changes

"DeleteSaveData" & "DeleteGame" are now replaced by "ConfirmDelete"
Return SCE_KERNEL_ERROR_ILLEGAL_PRIORITY when priority < 0
Use a separate latch for osk dialog.
Add ERROR_LOG for Illegal Priority
Add comment "priority = -1 is valid"
Delay as sas core for p3da
UI : Shift in-menu items
Render-to-texture : Remove no longer valid game list comments
Only use a separate btnmake.
Fix savedata.
Better disassembly resizing
Add errors and rescheduling to sceDmac*.

The functionality seems pretty straight-forward.
Mostly implement sceDmacTryMemcpy().
Add basic support for rewinding (not enabled.)
While unthrottled, checkpoint rewind less often.
If loading state fails, rewind instead of reset.
Make save/load fail strings more consistent.
Savestates now work okay between git versions.
Warning fix.
