Ok
Download this kick ass game here;
http://www.abandonia.com/games/307/X-Com-Apocalypse
to play on systems from 2000 onwards
download this other program here;
http://dosbox.sourceforge.net/download.php?main=1
ok
unzip your Xcom3 file to wherever, but for default sake, C:\xcom3
run Dosbox
type without quotes;
"mount c C:\xcom3" <--- C:\xcom3 being where you installed said game
it should say;
z:\
so
type this
C:
now it should say;
C:\
type;
dir
should come with a list of programs, one should be something like;
XCOMAPOC EXE
just type this, no quotes;
"XCOMAPOC"
and voila
use ctrl + f11 to slow down if it seems to be running too fast, ctrl + f12 to speed it up
and alt + enter to full screen or window the dos program
k
any questions?
