Yep... I just double checked and the first 4 bytes of the header are the start address, and the end address. The plus/4 always loads whereever the tape wants... allowing auto runs with ease... I've even seen loaders loading more code, but using the left over space in the header as well!
I've almost got it working.. I have one that seems to work fine..
except I didn't sample ALL of it... just the header and a bit.. and I can't seem to reproduce HOW I sampled it!! Grrr...
