Just as a matter of interest, I fired up a binary file compare on these to see what was what.
There are exactly 32 bytes corrupted from 0xA4029A to 0xA402B9 inclusive. The rest are OK.
The bit corruptions seem random, e.g. 0x20 to 0x25, 0x20 to 0x91 etc.
If it had just been the last or first bit of one byte at the end or the beginning of the file then maybe you could work out some sort of solution to this, but this seems like a random transmission error or subsequent file corruption somehow?
All the CRC checksums for that 32 byte block are different too so, can't offer a solution, sorry.
Creating a Quickpar PAR2 from the good file and using it to repair the corrupted file needs only a small few kB PAR2. In the days of dial-up when a 100MB d/l would have taken hours, that might have been useful, but these days of course it's just another 2 minutes from another file server on broadband! LOL
Anyway, hope this is useful to you in some way.
