TGA to OIM compression script? Onimusha Textures

[reaperchop]

Hi, Apologies if this is not in the right place.

A long while ago, someone on here requested help with Onimusha 3 textures and received a brilliant script for extracting .TGA texture files from a .OIM archive. (https://zenhax.com/viewtopic.php?f=7&t=7162&p=31272&hilit=oim#p31272)

I was just wondering if it would be possible to get a script for repacking the .oim archive once the textures have been altered, or be pointed in the right direction?

I have tried using the reimporting command, but this does not work due to 'MEMORY_FILE' being involved in the decompression code. I have also tried the reverse-engineering tools with no luck. Unbelievably, information on the proprietary .oim format is not to be found anywhere on the internet, only on the previous forum here.

I would be very grateful if anyone with the knowledge could help me out, Ive attached some files for reference, as well as the Oim2Tga.bms script provided before.

Thanks in advance.

This is a Noesis plugin that supports input and output OIM files. Limited by Noesis, the output OIM only supports single file. If you know programming, you can write a tool for packaging and merging.

Thank you so much!

Very limited knowledge on programming, but I've got the time on my hands to learn a bit

I cannot thank you enough for this, this is very promising
