Adds The Mansion and Club Doom to Doom 2 as new secret maps, and includes patches for The Master Levels and NRFTL as episodes
Update 9/5.1: Fixed The Mansion secret exit pillar on the other side.
This mod adds the Ps1 exclusive maps Doom 2 The Mansion and Club Doom, which can either be accessed from a Map16 secret exit or can be idclev'd to as map33 and map34. (Hint: the exit involves a switch and a teleporter on the far side.) This addon is for Umapinfo ports including Prboom+2.6, DSDA-Doom, Doom Retro and GZDoom.
This mod also contains optional patches to add episode support to The Master Levels and No Rest for the Living, and includes additional support for their fan midi packs.
To do that first you need to source your legally acquired wad files, You can download The Master Levels from Steam and download Blzut3's Master Levels patcher here, once you've done that, unzip the file and run the program, leave the map order and music as they are and browse to where your master\wads folder is in your master levels for doom folder, the most common place is C:\Program Files\Steam\steamapps\common\Master Levels of Doom\master\wads, now press ok and put your new master.wad with the rest of your wads or in the sourceport of your choice's folder.
Next, you can download No Rest for the Living from the unity addons section on the official port then you go to C:\Users\<user name>\Saved Games\id Software\DOOM 2\WADs then open the folder named 3, copy the blank 3 file and paste it to where your master.wad is, rename 3 to Nerve.wad
For the next step you'll want to open the Rom Patcher JS website and select the MasterlevelsU.bps file as your patch, then select your master.wad as the rom, rename the new file as MasterLevelsU.wad save it next to master.wad. repeat the process with NerveU.bps as the patch and Nerve.wad as the rom, rename the new file as NerveU.wad and save it with the others.
Now you can drag those files including D2console.wad onto the executable, open them with a launcher or create a shortcut, right click it, click on properties and edit the end of the target with -iwad doom2.wad -file D2console.wad MasterlevelsU.wad NerveU.wad and now you're done.
You can also play the expansions with custom midi packs if you want, you can preview and download the files here (Master Levels) and here (NRFTL), make sure you download the prboomplus version of the NRFTL midi pack, and run the online patcher with their respective patches, and add them to the end of your laucher or shortcut (optional).
Disclaimer: this addon distributes modified iwad assets, only download this if you have purchased Doom 2 and its expansions and keep backups of your original wad files.
Known bug: Express Elevator's secret exit to Bad Dream doesn't work, this is a source port issue that may be fixed with future updates, you'll have to idclev to map55.
