Making mame run faster

Jarrod · Post by **Jarrod** » Tue May 15, 2001 12:30 pm

I am new to the whole mame thing so try not to treat me to harshly

my problem is when i run raiden (it happens in some other games too, but not as noticable), when there is a few enemies on screen it really slows the game down, does this happen to everyone, is there anything i can do about it, without breaking those rules and regulations that are set out for posting scores?



i am running a PIII 128mb ram plenty of hdd space, 16mb nvidia display card and am using mame32 ver36 final release.



any help would be much appreciated.
thanks
jarrod.

the real key is your CPU speed, but PIII's usually have really good
speed, 500mhz at ~minimum. Sometimes just setting a few things in
mame can help a lot, try running with out sound (single best speed
saver but no sound is sometimes annoying) , or unclikcing the
"disable" mmx, unclicking double screen size, and the best switch by
far, set frameskip to "Auto", displaying every frame is greate if you
have a speedily emulated game but if it's hard to draw you have to up
the frameskip to get it close to normal. autoframeskip is pretty good
at smoothing out the slow emulation parts of a game...

Well, before you go taking pains to speed up your game I'd hit F11 to
see if MAME is in fact running at 100% speed. A machine with your
specs should be able to handle Raiden, and the game does slow down if
I remember right (which is as it should be, it's being emulated
correctly and that's what it did in the arcades). It's been a little
while since I've played, admittedly.

Unluckily, there's nothing you can do, as they are the same slowdowns
featured by the original arcade.

In some games the emulation of the CPU speed is incorrect, resulting
in slowdown even if your game is running at a constant 60fps. This is
definitely the case with Raiden as I recently played the arcade and
it did not slow down any near as much as it does in MAME. Other games
I've noticed with worse slowdown than the arcade are Double Dragon,
Renegade and Chelnov.



cheat.dat and some versions of MAME allow you to overclock the CPU in
the tilde menu, this can alleviate the slowdown however it's probably
illegal to use overclocking in a MARP submission.

thanks to all your help guys,

yeah i do remember raiden slowing down a bit when i played at the
arcades, but not to the extent that it does, but then again i haven't
played the arcade version for ages, i'll try playing round with the
mame settings and see wat i can do, but either way i will survive

thanks again
jarrod.
