Someone posted in another <a href="http://boards.psxemu.com/showthread.php?s=&threadid=1500">thread</a> that the Yaroze 3002 bios gave them a speed boost. I've tried it, and I can't say that I can see a difference (although my performance was fine before... so maybe my system is fast enough that changing the bios won't make a diff.)

Question to those knowledgable about emu development: what effect does the bios really have on emu performance?

Thanks!

By my personal opinion
No.....No.....No......
I have test on many bios like 1001 5000 5001 7502 etc
I seem no difrence about speed..............
>what effect does the bios really have on emu performance?
Compatible is the answer.................

Hi,

I've tried 4 bios, which is:
1. scph1001
2. scph7001
3. scph7502
4. dtlh3002

I've try only a few games:
1. Ridge Racer 4 (PAL)
2. ISS Pro Evolution 2 (NTSC-U/C)
3. Chrono Cross (NTSC-U/C)
4. FFIX (NTSC-U/C)
5. Vagrant Story (NTSC-U/C)
6. SF3 Alpha 3 (PAL)
7. SF (.... I forgot, but the old one)

And I notice no differences beetwen them (like Enigma), but only the Yaroze 3002 (just got one....Tks Mtlmph) a little bit faster in FFIX. I will try this bios again with other game again.

But I'm sure that bios is the same with compability. My comment here maybe bias, because most of them are NTSC-U/C (America) and very common game, so everything is the same. I did notice that even with European bios, it works well with the American one.

Any comment from other Japanese game with European/American bios?

I have Galerians(Jap) and run with SCPH 1001,7052 and Yaroze with no problems...

Enigma said it....bios does not affect speed......just compatibility....

 

[Guest]

Yes, I agree, the Bios simply affects compatability. I live in the USA,
run NTSC US games, and use the 7502 Bios almost exclusively. The fact that the 7502 is a European Bios doesn't matter, it runs my games just fine.

Well, 7001 improves my sound quality dramatically......

ermm.... Isn't the Yaroze the stupid internet make your own game, PSX project Sony tried out? Wasn't it black? Wasn't it a failure?

no sound improvement here...

 

[FINALmasa]

Well, FFT has WAY better sound quality, and I notice some minor improvements in other games. I use the internal SPU.

Asz, I believe the answer to your questions is yes.

Ah... I remember I stumbled upon a Yaroze site a long time ago (a couple of years) and it sounded terrible... It showed example screens of a version of Galaga(I wonder if I spelled that right)

No effect at speed...maybe my com is fast enough to see the differentiate the speed...
