How to open a .PAC File? (Mega Man 8 PSX) - Rabbid4240 - 09-11-2022
Hey I'm trying to figure out a way to unpack a .PAC file for MM8 on PSX. I tried Noesis, PSicture and QuickBMS. But none of them recognized the PAC format. The file seems to hold both sound effects and image data, but I'm only looking for image data.

It can be opened in GGD and the like.

Wait is this the same as the .PAK file from Silhouette Stories? Because i'm trying to decompress those files too.
Nevermind, it's not the same as the .PAK file from Silhouette Stories. BTW, i'm trying to extract the files using Texter, the only problem is that when I decompress a PAK file, it says read only, doesn't exist, or used by another program. Any way to solve this?

No, the Megaman 8 .pac files aren't compressed.

MM8 PAC files are archives that contain all kinds of stuff like graphics, audio and even level data. I can't recall if there's any compressed data inside but I have programmed an unpacker in Python, I can post it here when I get home

If it'd help get the sprites from the eight Robot Masters it would be good.

I have lost my un-PAC tool, but apparently this tool https://www.romhacking.net/utilities/1019/ supports MM8 PACs

Ok, those .pac files are readable on TiledGGD but they don't seem to have palette data.

They do, they're just buried before major graphics sets. If you're using the separate boss PACs, you need to get the palette from any of Stages PACs, which usually have the boss sprites in them anyways.

I'm assuming those solo PACs were intended for Wily Stage 4 just as a space saving measure.
