Pretty cool but this should be a medium one, or even easy.

you can fix it by magic .

Hint : You have to edit something in the header

interseting : )

I was really struggling with hexedit ... If you think you've done everything like it's supposed to be done but the gif still cannot be open - I really recommend bless instead of hexedit!

Anyway, great challenge :D

Should be easy.

you can also use bless command to edit the header or hexeditor

I'd say it is not hard

Nice one! hexed.it helps a whole lot. Thank you javier!

Actually a really cool challenge!

File header missed a few characters.

too simple!
