When it comes to archiving human culture, this software offers a fascinating glimpse into how one company approached training employees circa 2009.

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
Only #1 and #2 have been archived.
As for #3, it might be possible someone has unknowingly purchased a PSP from the hotel, which has the necessary certificates, but it's unclear where the certificates reside in the firmware, nor if rooting procedures may delete these certificates.
Thankfully the software has a fallback that allows it to run without these certificates due to a possibly-the-same-possibly-older non-certificate requiring executable residing on the UMD.
Below is the fallback patch. To make use of it, you'll need a tool to such as TempAR running on a rooted PSP or the PSP emulator PPSSPP.

Cheats must be turned on right away
You'll need to set the refresh rate for the cheats in PPSSPP to 1/1000 and in TempAR to 5/1000 otherwise the cheats won't be applied in time
