The "stc-cmpn.ppf" patch contains the string "CheckMate [Pal NTsc Selector] (c) STATiC" in the .ppf description area. It further contains the game serial number "SLES_02917", which does represent the game "Checkmate". However, the cracktro itself, that is embedded in the .ppf file, shows "Card Shark" as title instead.
