More details: This is a cheap old box I’ve kept around to play WoW when I was into it, and the odd older or less graphically demanding game. (I’m not much of a PC gamer otherwise.) Windows XP, Intel integrated graphics.
First attempt to run the newly-downloaded 0.B exe always fails immediately, with a brief flicker of the window and no error message. However that first failed run creates the config folder. Within that folder I go to options.txt and set software rendering to ‘true’ by hand. The game then starts fine on all subsequent attempts.
Once a game is in progress, all appears normal except that acid streaks, smoke, shocker electricity, etcetera are all invisible in tiles mode. If I turn off tiles they show up as normal for ASCII. 0.A ran without issue.
