Have you renamed BATTLE.X to BATTLE.gz, Raziel?

Yes, I did what I wanted with ff7_gzip (FF7Dec + gzip) tools.

MysticLord:
It might be useful for someone to upload the decompressed version of the file, so you can compress it and see how it corresponds to the file you're working with.

It's been a long time since I worked on the BATTLE.X file. However, I did find the following README I wrote to myself, in a file from 2014. It was for running an assembler patch for long range enemy attacks:


--- Quote ---Here's the procedure:

- unpack the BATTLE.X by removing the initial eight header bytes (copy them somewhere)
- decompress the file as a gzip archive
- run the ASM file (enemy_long_range_attacks_asm.txt) through ARMIPS
- recompress with gzip (using the Cygwin version of gzip with the flags -9 -n will work best)
- re-add the initial header bytes
- reinsert your BATTLE.X file using whatever means you like

Where can I download this Cygwin version of gzip?
