Try a 0byte file? Exception.

scratch my last comment, here i was assuming that [klic] was text entry instead of a file read operation.

klic's 32 0's: [Register or Login to view links]

oh silly me, I uploaded the wrong one. Oh well, it has the same properties as the bgm0000002 one, free and edat v4. same error.

... Well now I feel stupid. The error was because I opened it in notepad++ and typed 32 0s.
klic is to be read from a file that is compiled with a hex editor. So I opened HxD and wrote one line of 0s, and now it works.
Brilliant. Another PEBKAC, I think I should think and do a bit more trial and error before typing.
Much thanks to User and Belmodo, I've been obsessing over this most of the weekend.

To quote: Hi, Belmondo and me thought it would be time to just drop this here.

Enjoy

PS: extracting compressed edat/sdat is supported, creating isn't. However, you can finalize compressed debug edat/sdat.

Edit: ofc creating and extracting uncompressed edat works as well... let me know if there are any issues. it works with every file i tried.
