While playing my Ds games on Desmume, especially pokemon Black and white, the games played very slow. So I went on youtube and did a few google searches as well and tweaked the settings to speed the settings up so my games wouldn't lag bad, and I fixed my problem with my settings and yes I know it has to do with my own computers specs and what not. Anyway, i manage to get the games running fast, the problem is now they run waaaay too fast! anyone know any settings that I should try out that would reduce the insane speed issue I am having on desmume?
What your PC spec? Change Frame Skip number? How about select Open GL instead of SoftRasterizer? Visit this website for more information. http://wiki.desmume.org/index.php?title=Faq
Try No$gba. It's much faster, and the graphics are much smooth-looking. But you got to endure low quality audio though.
Newer build, I must admit a bit faster on my pentium 4 2.4GHz http://www.emucr.com/2011/05/desmume-svn-r4002.html
