Final DOOM Anthology IWADs default to Anthology EXE.

[Acts19quiz]

The current philosophy behind the handling of Final DOOM's IWADs is to default to "final[1]", not "final2", since that's what most people might reasonably be expecting, given that those are the common IWAD variants used. I think that's a good idea (not that it matters, but I digress). However, players that (apparently) go out of their way enough to use the rarer Anthology/GOG variants probably know what they have, and likely want accurate reproduction of those IWADs' engine 'out of the box'.

The idea then is of course to scan the IWADs' (plutonia.wad and tnt.wad) lumps to determine what is what. I believe there are enough differences to create a concrete, grief-proof search. Feel free to chime in if I missed an esoteric variant.

gamemission must be either pack_tnt or pack_plut
+P1_START
