Thanks .....

i already solved it before i read this thread...
Now i have ArcadeOs as Computer starts.
****PROBLEMS****
1) 266 Pentium 2 COMPAQ Branded.
128 MB SDRAM. ATI rage video card. (i think 2 MB)
I am using dmame 87. Games are running slow.
specially neogeo games.
what should i do to increase the speed?
frameskipping is useless.
2) Video/Resolution of most games is not fit to my PC monitor
screen.Only neogeo games are best fit.
I read somewhere about a software SCI DISPLAY DOCTOR.
How to set games with fit to screen with out setting the
monitor?
