Custom Compresion

Post by MrBuu »

Hello everyone,

I'm looking into a file that used to be uncompressed but was later compressed in an updated version.
I tried comptype2 already and had unfortunately no results.

The file itself was a lookup table for the main archive.

Here is a screenshot of it uncompressed,

Here is how it looks compressed.

Between these two versions, the compressed file is ~2-2.5 times smaller than before.

I attached the compressed file. Unfortunately there is no header or anything really to go by. Maybe someone can help though?

Thank you in advance.

Do you mind telling us what kinds of program are you using to compress this with? if it's a game or something similar, it's possible to reverse the function or the code.
