has anyone tried the VGBA emu on a PDA the Morphgear one?

I've been in prelimenary contact with the author of VGBA Marat Fayzullinn he says he MIGHT be interested in porting VGBA to GP2X

there have to be certain incentives involved namely money which could be taken care of Im just wondering weither it will be worth it

anyone?
 
if he's willing to create a playable port of it maybe ED will give him a 2X for testing / doing it etc..
and of course dev discounts on all acessories etc..
 
Heh, I'd stick with talking about personal donations. It's dangerous to volunteer someone's donation.

But heck yeah! I'd donate to a GBA emulator that runs well. All my kids ever play is their GBA & GBA SP in the van on long rides. They kept asking me if the GP2X would play "their games..."
 
I ve had a PDA/Pocketpc with Morphgear on in
Pocket Loox 700 @ 400 mhz, but I remember was real laggy at SNES, havent tried out GBA.

EDIT I got now a HX4700 @ 624 Mhz I think its a bit useless to test GBA emulation on it
 
decent GBA would be awesome!
Im sure that the author would get a lot of donations, including one from me :)
 
I have been using that GBA emulator in morphgear on my pda for sometime, its a great emulator and I would be more than willing to donate to such a project on the 2x.
 
A decent GBA emulator for GP2X would probably mean me pawning my collection of GBA games, My SP and forwarding what I get to the dev responsible.
 
I thought there were plans porting PocketGBA (sunbug.net) to the GP2X?!
I've tried this one on my PDA (400MHZ): seems to be better than MorphGear!
 
I used the MorphGear GBA emulator and it was hideous slow even on an XScale processor at approximately 700 MHz (usually 624.) I could achieve rarely over 10 FPS. (Bear in mind the performance of a 700 MHz XScale is approximately that of a 300 MHz 'true' ARM9.) It did appear to utilize a C processor core for the ARM7 emulation, and that's going to be the real problem to overcome. A 16 MHz 32-bit processor like the ARM7 is stressful as hell to emulate even on a 200-300 MHz ARM920T like that in the GP2X. I have a strong feeling that project for the GP32 that involved running the GBA's ARM7 code natively on the ARM9 processor, then doing things like audio, controls, video (video handling, palettes, scaling, rotation, etc.) emulated. This way the main CPU will not be so overburdened.

That said, if a fast enough ARM7 ASM CPU core is found or created, it is possible to achieve full-speed emulation, concievably. But it does appear unlikely given the amount of stress created on the ARM920T by a 12 MHz 68000 core! Tacking on the GBA's rather robust 2D video subsystem is quite another task to pile on top of it indeed. Perhaps if the ARM940T could be utilized in some helpful manner, it would be a saving grace for such a project.

That said, were this individual to develop a playable GBA emulator for the GP2X using an ARM9 ASM core, interpretation or what have you to achieve acceptable performance, you'd see donation money from me as well.
 
Bad news is still news, so I am posting here the short communication I had with the author of VGBA.
I tried to prod him towards porting the emulator to GP2X by sending him a link to this thread.
Hi full answer follows:

At the moment, I am not planning to port VGBA to GP2X. I have neither
GP2X nor time to do the port, and do not see how I can profit from it.
Thus, the enthusiasm of your forum members appears misdirected to me.

Let's put ours hopes in other projects.
 
I like the "profit" ribbing, which implies the GP2X is itself... unprofitable.

Well sure, compared to making a game for the Nintendo DS.

Ah well. I'd just say "I don't have time." That's honest, and not overly so.
