Tutorial: Mod better voices into Duke Nukem 3D by Akula
I have to apologize for the lack of updates this past weekend but I was away so I couldn’t post anything. That means, however, there there are tons of things to write about, but I’ll start with stuff for the PS Vita.
Over at the wololo forums, user Akula has been doing some playing with the PS Vita version of Duke Nukem 3D: Megaton Edition. He was aiming to initially only insert the high-definition textures into the game. That little experiment failed, but it gave him other ideas. Here’s in his own words how he went about it:
So I noticed that the structure in the app folder involved the .def and .grp files. I figured it’d be worth trying to install the High Resolution Pack. It sort of worked. The problem was the game was very choppy, and several of the assets were misplaced on the hud. However, this does open the option to mod Duke Nukem 3D, so long as the mods can run without eDuke32, such as any mods for the Steam version
This didn’t stop him from tinkering around like any brave explorer should and led to him modding the voices of the game. That is exactly what we are going to go over in the next section. Remember that you need the Megaton Edition of Duke Nukem 3D for the PS Vita for this!
Instructions
This mod will allow you to insert better, higher quality voices of Duke into the PS Vita game. These voices were recorded by Jon St. John himself and sound much better than the original ones.
- Download the audio files here: https://mega.nz/#!mZsGzbbI!g8_NF3SzGNkQ … rIaPhtJmnM and extract them to a temporary folder on your PC
- Download the Group File Studio here: http://dukertcm.com/knowledge-base/down … /gfs31.zip
- You’ll need to get a duke3d.grp file, I pulled mine from the Steam Megaton Edition, but you can also grab it with VitaShell and a FTP client, such as FileZilla. The duke3d.grp file will be located in “/ux0:/app/PCSB00437/Game” on your Vita (the folder will be named PCSE-00339 if you own the US version)
- Open the duke3d.grp file with Group File Studio, and right-click on the “Sound Files” section, then click “Insert Files”. Navigate to your temporary folder, and using Ctrl-A or shift-click, select all of the .voc files you extracted in the first step, and click OK. Now, it will ask you if you want to replace the files already in the .grp file one by one, so you’ll need to click Yes for each, however, it doesn’t take that long. After you have finished inserting the files, click save and wait for the process to complete.
- Once that’s done, send the duke3d.grp file over to your Vita using the FTP client and VitaFile to “/ux0:/app/PCSB00437/Game”, and enjoy the new better quality voice of Duke Nukem!
It’s a rather simple tutorial and all I had to do was add the ID of the US version of the game. Hopefully someone will figure out how to mod-in the better textures, though the framerate might still be an issue. Still all credit goes to Akula for his findings and sharing with the community. Thanks dude!

Its nice to know that we can now be able to mod duke nukem 😀
Are these ALL the voices from the new version?
I really don’t want to hear Duke say “BAZINGA!” again…
Haha, no. Just the ones from the original game, which were re-recorded.
This is very cool. Always nice to be able to improve a port’s quality
Now, if only we knew how to add custom levels to the game… i’d be an happy man !
Funny you should mention that, that’s my next goal. It’ll likely be a chapter replacer, and the added levels will likely have to be built with base assets, but I’m hoping I can get it to work.
