Few games work

I have a Mac with Mountain Lion and I downloaded the version that is compatible with My mac, some games such as "Scribblenauts", "pokemon diamond/pearl/platinum" and "Final Fantasy Ring of fates" but almost all other games don't work and come up with a blank white screen when the Rom is loaded, this includes games like "Pokemon HG/SS and B/W". I have tried playing with all of the settings but nothing seems to work.
How do I fix this?

Re: Few games work

While you may have a Mac version of DeSmuME, the question is: Do you have the latest Mac version of DeSmuME? The latest version for Mac is v0.9.8b. I can definitely confirm that all of the games you just listed do indeed work in v0.9.8b on Mountain Lion.

Re: Few games work

It seems like after you load the ROM, the emulation doesn't run. After you load a ROM, choose Emulation-->Execute.

You can also automatically set the emulation to run upon loading in your user preferences. To do this:
1. Choose DeSmuME-->Preferences
2. In the DeSmuME Preferences window, click General in the top bar if it isn't already selected.
3. Under ROM Behavior, check Automatically Execute Emulation When Loading a ROM.

Re: Few games work

Do you have Advanced Bus-Level Timing enabled? This setting can help improve ROM compatibility.

Re: Few games work

Are you using external firmware? If you are, try disabling it.

Re: Few games work

I'm not using any firmware, would the type of Mac matter at all?

Re: Few games work

Sure, what's your Mac model identifier?

Also, what ROMs actually do work for you?

Re: Few games work

I need your Mac model identifier. You can find it by using the System Information app in your Application/Utilities folder.

Also, for ROMs that don't work, what exactly "doesn't work"?

Re: Few games work

This seems like a ROM issue. Pokemon ROMs are notorious for having random patches and cracks that may interfere with DeSmuME's operation. You'll need to find a different a version of these ROMs and try again.

Re: Few games work

Zelda:PH was also a game that was tested for v0.9.8b Mac. In fact, I'm playing it right now as I type this. That ROM definitely works too.

It could also be something wrong with your OS X installation itself. You may want to try doing a clean OS X install and try again.

Re: Few games work

You need new ROMs. Your non-working ROMs must be corrupted, which is why they aren't working.
