rom compatibilities and speed issues


Recommended Posts

Hey d00ds,

 

Just getting into the home arcade enthusiasm, figure its a good outlet for my electrical engineering study and love of games.

 

I have a Street Fighter Alpha 26" cab on the way, and am going to go the mame route, and have been preparing a PC in the meantime.

 

Any ideas why it would be running slowly? I am using command prompt mame on a fresh XP install, and with 0 frameskip it seems to run around 60%. I thought this could be normal on SFA3, but not frogger or qbert...

 

Its a p4 1.6ghz, 256mb ram, onboard graphics. To run SFA3 at around 100% it needs 7/10 skipping. Any ideas?

 

Finally, i got a heap of roms off my xbox that have been on there for 3+ years, and alot of them dont seem to work (says files missing). Does this sound like theyve copied wrongly or i may need newer versions to match the newer mame.

 

On that note, would anyone be willing to burn me their working collections if i send DVDs etc? Or if you're in brisbane ill get you a carton?

 

Thanks Guys,

throw at least another 256meg of ram at it.xp is so incredibly slow with 256 meg even before you put any thing on it to begin with.in fact i dont sell any pc's to customers with less then 768 meg of ram installed if they want xp as they will turn around after a few weeks of having 256 meg and complain how slow it is.

 

onboard graphics should be ok, depending on what chipset it is, i have a p4 2.4Ghz with onboard graphics and it runs mame quite fine.if after the ram you have no joy, swap the cpu, aim fairly high so you will have get a bit of extra life/use from the cpu, aim for the 2.4 Ghz region, too much is always better then not enough

 

with the rom issues, there is a few rom managers you can try and run to see if they resolve the issues.

i use this

http://www.romcenter.com/

 

others use this

http://www.clrmame.com/

 

i prefer rom centre as you dont need a pilots licence / uni degreee to drive the thing

 

and cos its a windows based machine, they fragment like hell in no time, read this thread

thanks will try those out!

 

When i install it, i intend on using MALA frontend with it as my windows shell. Does avoiding the windows shell GUI produce much of a gain?

 

Cheers

Make sure all your drivers are installed for your hardware, sound video and motherboard chipset......that system should run those games ok even on xp with 256 ram.......sure thing you could do with more but it shouldnt have that much of an effect on the performance of it, i have a system here with 256 meg running mame and it works fine.

 

I run mame32 on that same system, its an old athlon around 1.6 ghz i think

With regards to the speed issues, i have noticed stating mame with -video ddraw improves this alot, what is the difference between D3D and ddraw (obviously they are diff DirectX display but how does that translate to end usage).

 

Its still inconsistent...Alpha 3 runs 100%, whereas puzzle bobble 2 still lags around 85%

 

Any ideas? Ive got new graphics and sound drivers...its an onboard SiS 651...
