well, i see what the main problem is...
tr8 - securom 7.40.06
tr7 - securom 7.39.06
tra - securom 7.36.12
so, totally different versions of the protection, which would have different generated code, the actual tr8 patch looks like the person spent a hell of a lot of time figuring out the patch, so its not a 'portable' patch unfortunately
which makes things a bit trickier
