You're wrong. I got to know about this project back then when Nintendont just WOULDN'T work in a wii Family Edition. it took a bit of time but they managed to find out that it was due to the Hollywood version being 0x21 and then it was solved. The test versions you're talking about were meant to find a way to change that fix so it would work in every console without affecting stuff like the power button. Spyro works perfectly fine, I just tested it and was playing for a bit.
I remember he had say in the past that he had some problems and after a mods revisions by FIX94 it works for him.
