Namco Museum Remix "EMY","PTK", and "ANT / ANP" files

Post by Garo »

Sorry for technically doing a repost (on behalf of the PTK and ANT / ANP files), but I realized no one was able to use the link. Sorry.

So in Namco Museum Remix (A Wii game from 2007), there are various minigames featuring arcade games with twists, these twists are called "remixes". There is a minigame called "Galaga Remix" and it's basically just an on-rails shooter with Pac-Man in it, and there are enemies that pop up on the screen.

(I promise it's not a rickroll)

The game stores these "enemy pop ups" as .emy files. They compressed in a weird manner, and they have no magic header. Here are some examples.

So the second archive I mentioned, "PTK", is a weirder one. Header is 'UKTP162N'
This one is quite a mystery, just for some context, I have only found "PTK" files in 'resident' folders. From my understanding, 'resident' is just a way the game organizes shared assets for the minigame or level. There are "PTK" files that have names like 'GAMEOVER' and 'LENSFLARE' to back up my case

Now there's a third archive called "ANP / ANT". The reason I call them "ANT" or "ANP" files, is because the names start with 'ANT_<FILE>' and the header starts with 'ANP 150'. I don't know what they do at all. They also come from resident archives.

I'm sorry for the inconsistency for the "" and '' quotes.

Notes: These files come from the 'g01resident.lzs' files
