/vr/ - Retro Games

Looks like for some reason my Zandro start skipping text screens (you know, that thing before secret levels, Dead Simple and so on). Though I'm pretty sure I didn't do anything, but for the last week I've been messing with mods and custom maps (UDMF and all other source port magic), so may be it's some leftovers from some sloppy mod/map. So, where to look? I don't remember at all if/how text screen cam be turned off. I looked at ZDoom Wiki, but there is no info about it (though plenty about how to change it).
