The difference in that is that if you can't get a high FPS in the first place, removing the limiter won't do much, whereas what he seems to be asking is to force the program to generate more FPS. It's just impossible, it seems he simply misunderstood what the concept behind the "speed increment" is, because it's basically just raising the fps limit, from what I understand at least. You(zeromus) were right in practice, but you might not have understood what he was asking for(which he himself didn't seem to clearly know either).

Back on topic, it's a feature I'd stronly appreciate, and like blinko, I not only believe it's possible, I also know it is, for the reasons he mentionned and because, quite simply, no$gba's no$zoom did it. Unfortunately, my programming skills are largely sub-par, limited to copypasting what I can get my hands on while changing values where I see appropriate and such, so I couldn't "just do it".(though I could pull a quick photoshop edit! but I personally believe in the possibility of blinko's success in doing the windowsplit).

As useless as my post could seem, all I mean to do is to give some motivation to whoever would want to actually go forward with making this feature, like blinko supposedly did.
