That was my ideal, but there are two problems:

1. Hex editor is real strange with copy and paste. Will have to spend lots of time trying to get things pasted in correct place.
2. There are subtle differences between $0D and $0E. Some tables are longer, some parameters aren't there. This adds up to things being shifted slightly. Would have to take this into account, or it will be the same as using the wrong xdf to view bin. If you try to run engine, at best won't start, at worst damage.
