Mamewah runs slow - see Oct 22 post

Not sure I completely understand. Specifically, if I run a rom from command line, isn't using the mame.ini? If so, wouldn't I have the same problem?

It is using the same mame.ini, but 'resolution auto' might not behave the same.

Not trying to doubt the solution - just trying to figure out the "why".

Is it because mame.ini is set to auto and I have mamewah set to 640x480?

Lets say your desktop res. is 800x600, and Mamewah runs at 640x480.  Run a game from a command prompt (your pc will be at 800x600 - desktop res.) and mame's 'resolution auto' will pick mode X.  Now run the same game from Mamewah (res 640x480) and mame will pick mode Y.  Mode X & Y might well be totally different resolutions (or they might be the same) - I'm not sure exactly why this happens, but it does.

Edit: as anyone who has an ArcadeVGA knows, 'resolution auto' doesn't always pick the best mode so I presume it is just a flaw.

Extremely helpful, thanks again. I'll try it and let you know how it worked.

I went into mame.ini and changed resolution from auto to 640x480. Which is what my desktop is currently set to. It didn't make any difference, unfortunately. Same thing  - some games run fine, some games just give me a black screen.

When I go into Task Manager, I see "mamewah not responding". Closing mamewah and mame either has no effect, or takes too long and I end up rebooting.

The problem is Mamewah is waiting for MAME to quit, it is not actually not-responding.

Two other things you can try:

1) Make sure you don't have frames_to_run 1 set in mame.ini (some people were using this to skip warning screens)

2) Set {safelaunch} in your commandline_format instead of {nosafelaunch}

Leave the resolution set to 640x480 just until you have it working.  BTW you can set this to anything (doesn't have to be your desktop res) - it's just important to change from 'auto' as this can have unexpected results.

I'll give that a shot. Thanks again.
