ZDoom

It disables any autoloading of files that do not directly belong to the game being played.

tyvm. Added to wiki.

It seems to disable the content of skins and anything specified in the autoload section of the ini. In addition, it also disables zvox.wad

It does not disable Deathkings (hexdd.wad) nor voices.wad in strife.

Does this disable reading of the skins folder as well, or just the stuff from the autoload sections of the INI? Does it prevent other files from being loaded in when not explicitly asked for, such as the Hexen expansion or the Strife voice file? For the wiki, y'know.

Added.

I third this.

Likewise. Everytime I don't want nashgore to autoload, I'd have to rename my nashgore folder to nashgor. :P

I'd like this too.

Is there a command line switch or something similar to disable items that are set up to autoload? I don't think so, so I thought I'd ask for one. The reason is, I have a few files set to autoload but, every now and then, I need them to not do it so that I can test something (usually checking for a bug) and I either have to edit my ini, rename/move the files in question or, sometimes, rename my skins directory and then put it all back when I'm finished testing.

However, just adding something like -noautoload to the command line would allow me to run an instance of Zdoom with nothing other than the IWAD and anything else that I'd put on the command line, and then not have to reset everything afterwards either.
