A few general MAME queries by a relative Noob.

Thanks - I'll give it a shot during my next update.  Maybe I can get all my games in one MAME.

See this and my billion other answers recently. Seems like everyone is asking this question at the moment.

You see I clearly meet that second spec, yet if i switch between a couple of games, or play for 5-10 mins, I start getting slowdown, frameskip and soundstutter?

I'm guessing its the RAM (or lack of) it's a pretty basic fresh xp install so there isn't much else going on.  I was using maximus arcade but i'm getting the same thing through the native mame menu too.

See this thread for an answer to that:

You have to edit your mame.ini file (If you don't have one, type mame -cc at the command prompt to make one).

It defaults to:

--- Code: ---# CORE SOUND OPTIONS
#
sound                   1
samplerate              48000
samples                 1
volume                  0

--- End code ---

Change it to:

--- Code: ---# CORE SOUND OPTIONS
#
sound                   1
samplerate              24000
samples                 1
volume                  0

--- End code ---

That will speed everything up, without having to skip frames.

Tiny XP will help a lot too.

Can you elaborate a little on what that change does?  Not sure what samplerate is.  Would this be helpful for anyone running MAME or just in this case with the smaller amount of RAM.
HaRuMaN:
The higher your sample rate, the better quality sound you will have.

Samplerate: times per second the sound is sampled, or in mame's case, emulated.  If the CPU is just barely not able to emulate the sound cleanly, reducing the samplerate might free up the CPU enough to clean up the sound.

It's not a memory thing (AFA mame goes).   (The mame docs/config.txt file talks about this a little.)
