I'll tell You this I've reinstalled the original dos version From Fallout CD In concern some of the extra files from gog version might screw with dos game...
Unfortuneatly the crash to dos appear after installing FIXT (the worse thing is it removes original Fallout.exe - the original dos exe, and there is no way to play it untill reinstall without FIXT in dos)
tried evrything disabled hi res patch through it's exe -nothing, then moved hires txt and dll to diferent folder - nothing, then also moved ddraw.txt and ddraw.dll to diferent folder - sill nothing
(
just don't know what's causing this.. I do not think it's the diferent exe name the FalloutD.exe (thouth the original was Fallout.exe) because i've tried with skynet's child patch exe (modified 1,2 UK to add children support crated by skynet thanks to me begging him
) version and it did not work with Your patch as well, and skynet's dos exe works fine on a clean install/teamX patch only just w/o FIXT megapatch.. keep me posted though, i'd like to help You on this one all the way I can.
** EDIT***
UGH.. it took me a while though i've figure it out finally..
we were searching in wrong directions the problem was not in hires patch nor ddraw's nor any other dll additionally atached to the FIXT
problem was in fallout.cfg in the position "art_cache_size=" was way over the roof and set to 64 (dont know why though) the original value was 5 when I go beyod 40 on this position it removes sound from first map and go to 45 and fallout crashes past loadscreen.. case solved
Just in mind Dosbox can map only 31 MB of RAM (and an additional 1MB RAM for system/kernel/whatever) so we should not reserve too much memory for certin things because we may run out of RAM, besides there is an other value set too high in the fallout.cfg wich is:
[sound]
cache_size=10240
wich should be
cache_size=448
yet another RAM waster or so i think..
free ram in dosbox is important for maps such as HUB main city map wich consumes a lot of resources.
Hope those setings are not that important and that lowering them won't ruin the gameplay somehow.
on a side note the red main menu background is kind of bugged in dosbox and there is no way to enter settings from main menu like in windows version of FIXT
Hope this helps best regards
