well if its running slow on standard 600mhz, i guess we can always overclock it to 1ghz.

then it should run smoother, i saw someone recored a video on youtube, playing tony hawk skating on PS stimulator with 1ghz overclocked.

No.. I have it running at 950mhz and I'm pushing it at 10FPS for most games barely. Its pretty annoying.

But then again, Desmume has never been the fastest or most optimised DS emulator for the PC (that award goes to No$GBA that also does DS games and is closed source). Its clearly stated in the FAQs that Desmume is slower only to make it more compatible with more games.

I know it uses the GL libraries - but is it actually pushing it through the hardware GL (or is it software)? Also, it might run better (but slightly less compatible) if we can skip the sound emulation?

Hoping you guys can sort this out.. Happy to contribute via PP if its required!

I don't fully understand your rambling, but if your asking if the DeSmuME Maemo Edition is using the N900 DSP than no. I can't of course say for certain, but the author of DeSmuME said that the emulator needed a major rewrite to get it OpenGL|ES compatible as of now and Smoku said he had just been "Toying around with the SDK".

Well what he means is that (Well I bet you already know Smoku) the N900 and the NDS both run ARMEL based CPU architecture. And to add on to that both the devices as far as I know use the ARM9 instruction set. Herman here beliefs that this makes it easier to make a quick and dirty build that passes the instructions over to the CPU, but that is not the case Herman. Though what this means is that if one individual that knows a lot about the ARM9 instruction set and these devices and is a talented coder, could if he spent a lot of time potentially optimize it a great deal...

Never the less, my bet is on implementing OpenGL|ES which would yield a large speed boost for any graphically heavy application.


My take on the fullspeed matter:
Is fullspeed possible? I don't see it ever become fullspeed on such a device as the N900 or the Pandora, but 24 or 32 FPS which is by far playable is possible, but require time and talent. (this is about half of the fps, but it would be really smooth, and faster than the eye could see)

I don't know if Smoku is willing to give the time and effort for this to happend, and as far as I know he would have to learn a lot more about OpenGL|ES. Id be happy if he proves me wrong, and I really like your work Smoku, and you are by far a better coder than me

Smoku.. good on you for putting those improvements into your build. Love the side-by-side orientation and it is running a tad faster than the previous builds along with the auto frame skip.

Keep up the good work!!

OK, I installed it and fiddled with it a bit. I got 2fps on Lego Star Wars. Clearly I need a less-ambitious game. Any suggestions?

Every game will be unplayable.
Even in Super Mario Bros i get like 5-10fps in game...

would be nice to see in portrait mode(one screen over the other) then using accelerometer, when flipping the phone the screens move side by side and maybe an option to view one screen at a time in landscape mode

Smoku already said that resizing the screens by fractions is not going to happened, so its either original or double the size. That limits the amount of layouts one can have.

EDIT:
If you want some numbers on the screens

the N900 = 480 height and 800 width (in portrait mode these are swapped)
the N DS = 192 height and 256 width (both the screens are)

so the width on the NDS screen times two is more than the height of the N900, this means that even in full screen you would have a crop when playing it in double size at portrait.

Side by side the nicest IMO would be to have one double and one normal size.

Resizing doesn't matters if emu works soooo slow.
