Try English in the future. You might get a few more answers.
I'm going to introduce you to a friend of mine. His name is Zophar's Domain, and he knows of a couple of good Gameboy Advance emulators. Here's his address:
http://www.zophar.net/gba.html
I know, I know, you came to an emulation site and you said "Hey, there's a forum. Let's complain and wait three days, to let everyone do my dirty work for me, rather than download an array of GBA emulators and find out what works best for my computer."
First off, I want to say you're full of shit. You've sat there and bitched and whined and moaned like any noob to emulation would. I bet you're one of those kids that goes on BitTorrent, downloads a rip of a game and then goes on the official website, or one of the larger fan-sites, and then complain about how buggy the game is, right? And then you toss in "Boy, I'm glad I pirated the game, because it's not worth my money."
Yeah, you remind me of that. Fucker.
I have an Athlon XP processor, with 640MB of RAM, and an ATi Radeon 9000 Pro 128MB video card, followed with a SBlive! chaser. My keyboard is PS/2, and my mouse is USB.
I could wipe my hard drive tonight and install MS-DOS 6.22, or even the latest release of FreeDOS, and it would run FINE. I'd have to track down some configuration tools, reacquaint myself with the secrets of autoexec.bat and config.sys, and I'd have to use that little USB-to-PS/2 adapter my mouse came with. I might even need a DOS-based driver for my sound card, God-forbid.
Ultimately the problem in running some games would be that my computer's just TOO FAST. The instuction set is there, but a lot of those old games were tied to a processor's clock cycle for speed. I could cheat and use something like SloMo to 'assist' me,, but that's the only problem I would run into.
That's why DOS emulators like DOSbox exist. To make the games actually playable by slowing the emulated clockcycle down... another reason they exist is because, frankly, not many people WANT to run straight DOS anymore. I run Windows XP Home on my computer, and it has a DOS emulator built-in. It's just not a very good one. (Thank you, Microsoft.) So if I want to play those old DOS games, I can configure the old DOS prompt for compatibility, but I'll run into problems with the sound card emulation. I could use VDMsound, but it's not very good. So, off to DOSbox with me to see if that old favorite game of mine works. Or to Google, to see if anyone's updated the game or recreated it in OpenGL/SDL/DirectX.
If you don't like VisualBoy Advance, try Boycott Advance. In some cases, it runs faster on my computer, although it hasn't been updated in a year, so some of the newer GBA games probably won't work. Someone else mentioned the "Collector's Edition" of VisualBoy Advance - I recommend you try that.
And keep in mind, while you might have a computer with a fast processor, it doesn't mean shit if your video card sucks. If you're using an on-board video card with the 'shared memory architecture' nonsense, then VisualBoy Advance will run like that yellow diarrhea your ass explodes when you've had a night of choking down double cheese White Castles smothered in german mustard.
Now. Why don't you quit bitching and go to the page I linked to above, and give some of those a shot. Then go over to this page:
http://www.zophar.net/frontends/universal.html and see if any of them support the emulator you find works on your computer the best. After all, you were complaining about not having enough features, right?
And after you spend a little time and get this all working, remember to go fuck yourself, okay? You could use the masturbation - maybe you'd chill the fuck out afterward.
Fuck, I'll even give you an assist where that's concerned. Go tell mommy and daddy that you're taking a nap and lock your door. Then go to
http://johndx.blogs.com/ and wank off for a few minutes with that tiny pecker of yours. That's right, bitch, you're gonna rock your own world, and when you're panting and sweating and leaning back in your chair with cum splattered all over your floor, thighs, and hand, you can take a moment and say to yourself, "I'm such an asshole."
Then you'll come back to the forum, apologize, and then go your merry little way downloading emus and seeing which one you like better, rather than bitching that the ONE your tried wasn't to YOUR liking.

On VBA, in order to get smooth enough speeds, I had a frameskip of 2 and no throttle, with 2xSaI (I prefer hq/lq2x, but it became a little to slow). However, on VBACE I can have the frameskip at 0(!), no throttle, with MameScale2x, and it runs DAMN near like a real GBA
