OF OF -> header02
02 -> Write09
60 -> Memory address
00 -> Unused
52 -> checksum
04 -> end
Two extra 5's are in there, compared to data, checksum is invalid off by 10.

What I think it should be...
0F 0F 02 02 60 09 00 04 0E DB 2A 05 0E 01 ....`.....Û*....
E3 DB 2A 06 0E DB 2A 07 0E 52 04 ãÛ*..Û*..R.

Checksum works, matches data in as well ^

How is it confirmed okay with an Invalid checksum?

Continue on, write next batch, ignore previous!?

Kinda unclear, no real documentation. I think it's just a bug in the IFI Loader, not sure. Or they don't have actual implemented verification, unless the verification could have been done at the end. Would have to rescan for that, it didn't capture the whole download only like 75% of it.
