Oh yes it works just fine. I'm just wondering if the PSP is powerful enough for a GBA emu.
Later,

The daedalus emulator has been updated to R5 now, and it runs mario64 from 10fps to 13fps, i think he made a dynamic recompiler or watever to get a good speed boost but im not to sure though, as for monkey64's emulator,quest64 does run about 12-15fps on pure interpreter emulation and quite a bit of 64 games actually work, so if monkey made a dynamic recompiler for his emulator i bet it would be AWESOME!, i cant wait for his future releases. he also said" his goal is to reach 30-60fps with sound and a good amount of games working, he also said that it would prolly take him about 6 months to acheive this.

FYI Strmnnrmn's dynamic recompiler (dynarec) for Daedalus is only about 60% complete so you can still expect performance increases from it as it is further optimised/updated. He's just been to Spain for a short break so hopefully we should hear from him soon as he had hoped that he would be able to do some quick compatability/graphics fixes and release R6.

in reality though, even with all the optimization, I never expect it to get more then 20 frames or so. PSP as powerful as it is, will have a hard time emulating N64.

prettzv, I believe so too...
The thing is that on Snes, the most cpu consuming part is emulating the whole chipset.
Which is a pretty messy process.
On the N64 side, it is the opposite : all graphics can be rendered directly with the PSP (just translation of graphic call, which is light).
The more they can extract juice with dynarec, the faster the emu is going to be.
I didnt look at the source code of his emu while following the progress (you can notice I even posted on Strnmnn site). The cpu is 80 Mhz in the N64.
Now the question then is how much Mhz of the PSP does it cost to emulate 1 MHz of the N64 cpu core.
In an ideal world, I would say that they can reach a 4/3 ratio for a pure code chunk execution. (really top of my head instinctive number).
But then you must add the logic to translate the calls, the audio emulation, VRAM emulation, and the cost of the Dynarec itself (translation, cache management, cache search etc...)
So to put it in a more simple way, a x2 compare to the current version is a BIG deal. And I would not expect too much more... But as I not the coder, may be there is some nice break through that could increase the speed.
This is also why I believe actually that PS1 is a good platform to emulate if done correctly.
CPU is only 1/10 of the PSP one and compatible. No hard chipset to emulate... Should work like a piece of cake if done well.
Lets see how far Sony will get it to work.
anyway full ps1 ISO on a memory stick is not really a very good business model ;-)
And it is funny to see that a GBA emu will take MORE CPU power to emulate on a PSP that a N64 ;-)
The ARM core and MIPS core are so much different, the GBA chip is also beeing closer to a SNES chip (=high emulation cost)
How to explain that to users...

This news is great but for some reason idk I think its too go to be ture. Laxter, or YOYO can one of you comprehend this in a coders point of view and tell us if this is possible. After all they did use your emulator as a prime example on how the rom loaders work.

Well, there is MANY WAYS AND FACTORS to solve one problem.
It may be possible, but so many people outthere that are coming from nowhere and shooting : "Look it will work like this, and like that, I am god !"
To be honnest, if the guy was really talented, he would have released an EBOOT so everybody can TEST it.
So, I am more in a kind of "wait and see" attitude when it happens that way.
I am really open minded when it comes to dev tech and how to do things, but when it comes to result WITHOUT SHOWING. I am a kind of non-believer.
It may be proove me wrong but... still I prefer to keep my "integrity" than believe every bullnuts outthere.
When I talk about POTENTIAL, I believe anything is ok as long as you can logically proove your point (=PS1 emulator SEEMS to be possible at full speed), but it is not like putting screenshot or video on the web saying it works. ;-)
About personnal project, no, I am involved with really annoying stuff at work, and I started new hobbies that are really time consuming (more than software programming).
So I am not coding anymore as I wish too...(too old already ?)
See ya.

Hmmm, I googled the name "zombi146" (the guy supposedly working on this emulator) and judging by the results, it appears this is definitely fake. Carry on, nothing to see here...

ps1 emulator is in the works anyway from sony so no homebru is gonna be able to compete with that  and googling "zombi146" doesn't mean anything, how do you know that whatever you find is related to that specific person!? |

Well it would be quite a coincidence if two different people used exactly the same screenname ZoMbi146, including the same misspelling of the word "zombie", both capitalizing the letter 'M' in the middle of the word, and both using the same number at the end. Anyway, after seeing some of his other forum posts its obvious that he's just some punk kid in need of attention.

Sony's PS1 emu is going to be worthless for me.. I'm not upgrading my firmware so I can pay to play games that I already bought years ago.

I agree. I am just going to wait until devhook gets that firmware working or until a homebrew coder makes a PS1 emu.

Often homebrew emulators are far better than "official" emulators from the HW makers themselves. See the SEGA games for Palm in contrast with LJP. LJP can run fullspeed Game Gear, scaled 2x with Scale2x smoothing, full 44khz sound and frameskip 0-1 on a 200MHz device. Now see "SEGA Sonic for PalmOS" running slow as a snail with no smoothing and an obvious HUGE frameskip. |

Hahaha Tinnus thank you for that. I was misinformed after hearing many people on the different boards talking about how sony's emulator will be perfect because they have all the hardware and coding that is needed. It's also funny that you beat the people at Sega by making a better sega emulator.

I think that is a fake. But I do think that Monkey64 and Daedalus will get them running near full speed.

The issue I see is not getting it to run at full speed (although it will take a small miracle or some coding genius). I see the biggest issue being ROM support since no PC Emu has gotten it right yet.

I have used PJ64 a lot and many roms are no good. I dumped my own stuff. Example F-Zero X, guantlet legends, kirby, mario golf ( still has visual glitches), mario tennis, etc. there are a lot of games that don't run properly. Some of the stuff PJ64 wont do NGEMU will, but neither is a super compatiable emu.
Unless you know of some magic plugins that I have never seen.

Hi guys...Very Busy laxer3A here :-)
Work until 2:40 AM last night...
Can somebody write a report/comment about the GBA emu ?
Personnally people are saying it is good, and fast...
But theorytically, it should not go fast.
So, what is the speed of most games in FS0 with sound off and on ?
Actually I am more faith in the N64 emu than the VBA one :-)
(except of course, if the VBA is tweaked to put compatibility down).
See ya.

hey watz up ppl, if any of you wanna check out the pspvba emulator for youselfs check it out heres the link dl.qj.net/index.php?pg=12&fid=8641 . check it out laxer3a its worth trying. |

Well, I saw comment saying that FF Tactics was running correctly with a FS 2.
Which basically 1/3 --> 20 FPS.
Still this game does not use a lot of effect, nor rotating sprite, not too much blending, but I believe quite color rasters.
May be games are doing less tricky things that was done with the Snes chipset, making it easier to emulate.
I would have tought that the graphics chip is very close to the snes and it is hard as hell to emulate it correctly.
The ARM cpu instruction set also is harder to decode than the snes cpu one and run at 16.7 Mhz which makes it quite costly to emulate.(but each instruction is less complex than the Snes ones... so... I dont know, may be cost is the same for each Mhz emulated.)
MMmmm... may be I should get in touch with ZX to see what is the neck in this emu.
I felt that ZX was a good coder, but not the kind to optimize ans squeeze stuff like Yoyo and I are doing.
May be I was wrong.
Well, the thing is that Super Mario World run around 100 Fps at FS0 with sound in TYL. :-)
So, still way to go...
