Re: VGBA-Maemo 3.5 Now Officially Released
 

black and white stripes or just a black screen and some crappy sound (I don't mind the sound though) appear on every games I play.

btw, the games I'm talking about are 128bit or higher roms. 32bit roms run fine and 64bits have some problems like i runs so slow at some point.

So any advice for me?:confused:

Can we please have a screenshot of that in this thread?

I know this is a stupid question from an ignorant bystander, but I'm curious nevertheless: how is it possible that a psp can emulate the gba almost perfectly with sound while the tablet is such a lousy performer?
It cannot be raw processor performance alone, since the browser on the psp is a joke and it is slow as hell.

PSP has acceleration?

Re: VGBA-Maemo 3.5 Now Officially Released
 

No idea, neither used nor programmed for PSP. It does seem to be more powerful than N8x0 though, based on the specs.

Re: VGBA-Maemo 3.5 Now Officially Released
 

Probably, but I don't know to what extent homebrew software can use it, since homebrew development isn't exactly blessed by sony.

Re: VGBA-Maemo 3.5 Now Officially Released
 

Maybe because Sony actually thought about the hardware that was going in the PSP. Granted, it was always meant to be used as a gaming device.

Still ******ed decisions from Nokia about the LCD Controller continue to annoy me every time I use mplayer. And the GPS chip in the N810 is another example of Nokia's brilliant decision over choice of hardware.

It has a 333MHz mips R4000 cpu vs the N8x0 400MHz omap (arm), so, in addition to playing games, it has to emulate an arm cpu (which, supposedly, the N8x0 doesn't need to, and I think you said you hand optimized some arm assembly routines).
Again, when you use the browser the PSP doesn't really seem more powerful, on the contrary, it's really slow, the n800 is a speed demon in comparison.
Maybe it's just the video subsystem that s***s on the tablet.

Re: VGBA-Maemo 3.5 Now Officially Released
 

N8x0 does need to emulate GBA ARM CPU, although I did optimize it using ARM assembly. Same can be done in MIPS assembly on the PSP though.

You are comparing apples and oranges.

I'll say great work to you fms even though I've not even got my tablet yet :p but based on what other people have said it sounds like you are doing a sterling job :) I hope you can continue development and I hope we can all support you.

I have a question, has anyone started a reference yet of what games work, what their performance is like and if they have any issues/problems? We should start a thread or at least create some sort of a list?
