1) download dosbox XD
2) extract it to your storage card
[warcraft sample]
3)make a new folder called "warcraft" on your storage card
4)copy all game files there
5)open dosbox.conf
6)
[...]
fullscreen=true
[...]
memsize=8 or 16 (depends on how much free mem you have)
[...]
frameskip=4 (well..find the fitting value yourself)
[...]
cycles=5000 (same as for frameskip, actual emulation speed results on how you set up frameskip and cycles i think)
[...]
(disable all sound devices,dont know if this improves emulation speed but theres no sound anyway)
nosound=false
[...]
mpu401=false
[...]
sblaster=false
[...]
gus=false
[...]
pcspeaker=false
[...]
7) well, still in the dosbox.conf , theres a section at the end called [autoexec] , since you can input anythin in 320*240 mode you have to write the game start sequence here, it should look like:
mount c "\Storage Card\WARCRAFT\"
c:
WAR.EXE
overclock, free as much mem as possible, run dosbox, wait, have fun(?) ... ^^
