PSP games Everybody's Tennis and MotorStorm Arctic Edge have been "suspended" from sale on PlayStation Network, Sony has confirmed to Eurogamer.
Unofficially, they've been removed because of an exploit to the limited PSP mode on Vita. This allows homebrew games and apps to run.
Sony Europe's official line to Eurogamer was this: "We've suspended sales of Everybody's Tennis and MotorStorm Arctic Edge for software stability improvement."
Suspended suggests they'll go back on sale when the loophole has been closed, but Sony wouldn't confirm this to be the case.
"We'll announce details shortly," was all we were told.
