If I remember correctly.
TOOL is for development but it has significant hardware difference with retail and is not being trusted for release testing.
That means if your program can run on tool reliably doesn't mean your program is going to work perfectly on retail too.
To resolve this issue and save cost, a more retail like system-TEST was made. You will need a lot of TEST more than TOOL within a studio for your QA testing team. These game testers will play the game on the TEST environment days and nights to make sure the program is ok. TEST has minimal development function and can boot master UMD (burnt to a DVD-R) and can resemble retail machines better than TOOL.
If everything is okay, the burnt DVD-R will be submitted to Sony for final check and UMD manufacturing.
Thank you for these details. Now i know if i should have a test kit as well which i believe is the case.
