Well, it seems that you (we) are out of luck.

Here's another test that you can do.
It won't work any better but it will tell us something.
The test is whether this loads 100% or only 8%.
It's "bad" because I put in a spelling mistake, re-hashed it but didn't re-sign it.
Just rename it from .prc to .bin

I went looking for an update.upx for the Poke5 but they haven't released one yet.
