I suppose I could adjust the priority of the threads, but thats silly without having the equipment to test on. But that is unfortunate because I happen to know that they need to be maximum priority right then. A scheduler might decide that those are lightweight threads because they dont do a lot of work, and schedule them on the same physical processor. The main emulation waits for that to finish. In particular, desmume's 3d rendering threads (really the only thing that multi threads are used for) sit idle for a long time and then wake up to render 3d. So maybe your approach is necessary to mitigate that. Its unfortunate but sometimes when you pile hacks upon hacks, things go haywire.

I suppose its possible that desmume's multithreading confuses the hacks which constitute windows scheduling system for hyperthreads, which are intel's despicable speed hack. Just try, and please reply if this helps you. I can go all technical and explain why this works, but then I'll stay here all day typing. EDIT: Note that you will need to repeat this every time you start the emulator! These settings don't save unfortunately. In this form, uncheck processors 1 and 3, leaving 0 and 2 checked. Right-click the process, and select Set Affinity So if you have a dual-core machine, and WinXP/Vista/7, try this:įind the process called: DeSmuME.exe or DeSmuME_圆4.exe The computer sees 4 separate processors, and assigns the DeSmuME process to all 4 of them. My laptop has an I5 processor, and this, like many other dual-core processors, have both dual-core and hyperthreading. I figured this can't be an emulator problem - and it isn't! The problem, as I've discovered today, was CPU affinity and hyper-threading. Now, I play this on my laptop, but this works, so get your skeptic faces off. I've basically been having ups and downs in emulation speed, when sometimes the game would play fine and fast, and at other times, while doing the same exact things, things would slow down to a crawl.

If you find this too difficult, then you can run "Delete DeSmuME Preferences.app" that comes with your Mac DeSmuME installation package, which will delete the file for you.I've been experiencing some speed problems when playing on the emulator, and still after reading the FAQ and lowering all my settings I couldn't get the nagging feeling that the emulator can be sped up a million-fold. The file is located at: ~/Library/Preferences/

(This is the standard behavior for Mac apps, and thus this behavior will not change in the future.) Reinstalling the app itself does not do this - only deleting the file can do this. If nothing else works, you can reset Mac DeSmuME's settings to their defaults. The relevant options for changing execution speed are "Set Speed" and "Enable/Disable Speed Limiter". You can click the Normal Speed button to reset the execution speed back to 1.00x.Īll hotkeys, including the ones related to execution speed, can be changed in DeSmuME > Preferences, and clicking on Input at the top. Try checking the execution speed in the Execution Control panel.
CaughtOne, the only way to do what you're describing is if you went into the Execution Control panel (by choosing Emulation > Show Execution Control.) and changed the execution speed by dragging the slider.
