This game was exclusively made for the Hilton Hotel's staff to practise. It only works in combination with a special MemoryStick. Only 500 UMDs were produced
The software has three parts:
1 - Memory stick containing software data and a certificate-requiring executable. These were archived via the Unix dd command and are contained in a disc image including MBR named: "ULTIMATE_TEAM_PLAY_MEMORY_STICK.img".
2 - UMD executable
3 - PSP with necessary certificates
