Homebrew CTRX - PS1 Emulator

[PandaMayFire]

Sweet, about how well does this run at this point in time?

See why do you have to do that? I'm minding my own business and you say that. Those people were trolls.

This is why:

Dear @teampleb, please stop flooding the thread with one (not necessarily wrong but) inflammatory post every one or two posts from other members. It makes reading the thread a test of patience and tolerance. I would /ignore you only on this thread if such an option existed. Although the same could be said of every newb that doesn't know to read the first post and ask if this would run games, or the ongoing senseless discussion about how to press L2/R2 on O3DS for the -no game that works right now and would require it-. If you want to discuss what movies to watch on Mars Cinemas, please do it not only after somebody puts his feet on Mars but after colonization has at least started.

@teampleb You respond to others with unnecessary comments which start two page debates that flood threads.

v0.6-alpha now available. This is mostly graphical updates from the latest commits of Caelina. Should be more stable on ninjhax2 and shouldn't break netloader on boot.

Downloading now.

Then why don't you answer their questions?

On New 3DS with ninjhax2, the puzzle demo runs relatively well and is entirely in a playable state. Old 3DS, pretty slow, takes -seconds- to recognize a button input.

Symphony of the night on 3ds? uhh!!

 

[ironmaster49]

Woah, progress! Does this support dynarec?

 

[puss2puss]

Nice progress!! Keep it up, its coming along nicely!

 

[machinamentum]

Woah, progress! Does this support dynarec?

A dynrec isn't implemented. There's plans for one, but it's not very high on my TODO list.

A little? You realize the ARM11 is the same processor used in the 2008 iPhones, right?

Albeit enchanced architecturally over those versions, yeah it's the same.

Ok one last point on this from me the Wii is more powerful than a 3ds and struggled to run playstation games and a lot of n64 games and the Saturn emulator ran games mega slow and you guys keep asking for 3ds emulators for the 3 of them can you not see the problem yet???

I think it's safe to say only the N3DS will take us to Wii levels of homebrew.

I think it's safe to say only the N3DS will take us to Wii levels if homebrew.

n3DS is a lot slower then the Wii.

With a processor 804 mhz and a RAM with 192 MB. Everything (almost) is possible! N3DS has 2-3x better hardware than the psp. So there will be more goodies for the n3ds. Hopefully this ps1 emulator is among the goodies

n3DS is a lot slower then the Wii.

And your proof would be? The architecture would suggest otherwise.

A once-over of 3dbrew as well as other reports says the clockspeed wasn't increased, only the number of cores and singlethreading.

Edit: 3dbrew was just updated and now shows 804Mhz plus a 2MB L2 cache. No doubt at this point, the N3DS is stronger than the Wii.

It doesn't suggest otherwise, the 3DS is slower than the Wii, it's not even a debate.

Correct.

 

[teampleb]

The architecture? They're both RISC. Only difference is that the 3DS is ARM and the Wii is PPC. I know it's slower because it's using technology from 2009 that the Wii was already faster then. ARMv6 isn't a very speedy instruction set. I know for a fact the PICA200 isn't nearly as fast as the Wii's GPU.

Again, claims=/=fact. Go read over the limitations of the PPC, then comeback.

PPC is closer to MIPS which is why it has some edge over ARM processors in emulation. Neither is from 2009, Wii's PPC is from 1999 and uses ancient in-order completion. The ARM11mp core is from 2005 and uses dated in-order execution, but OoO completion. ARM11 MPcore also has more cache, better efficiency and better pipelines. Pica200, 2008 model modified from 2006, is no debate either, it has much more advanced shaders and draws more polygons. Wii's tech is just too retro to compare favorably.

1) I meant that version of the technology is from 2009.
2) The PICA200 does not draw more polygons. It only draws 15 mil a second.
3) Got a source for any of that?

Spyro is once again spouting nonsense with no sources to back up his claims, I've explained this to him in different threads before to no effect. The Wii is at least twice as beefy as the 3DS, the N3DS cuts it closer, but has a weaker, mobile GPU.

It's hard to compare the two devices since one is ARM-based and the other is PowerPC-based - they perform different tasks in different environments, but if you want to calculate a raw performance comparison then DMIPS is a good measure.

Having this table in mind, we can calculate that the ARM11 MPCore architecture has the performance of 1.24 DMIPS per MHz per core, so altogether the 3DS's CPU would score around 659.68 DMIPS @ 266MHz. In comparison, the Gamecube's Gekko scores 1125 DMIPS @ 486 MHz (around 2.31 DMIPS per MHz, as other PowerPC 7xx CPU's) and the Wii's Broadway scores 1687.5 DMIPS @ 729 MHz (same architecture, so the same DMIPS rate used for calculation).

That kind of a result was to be expected since the 3DS is a low-power portable device while the Wii and the Broadway are home console CPU's.

EDIT: Just for the heck of it, the WiiU continues the long line of PowerPC 7xx-based Nintendo CPU's and as expected, its DMIPS performance is 1250 (MHz) * 2.31 (DMIPS per MHz) * 3 (Cores) = 8662.5 DMIPS... just for those who are curious about its average Integer maths capabilities.

Before someone accuses me of using an obsolete benchmark, at least it's a benchmark, not empty words - it's a sample of one versus zero samples. A gap like this (155% difference between the 3DS and the Wii) cannot be made up with fancy tricks - stop living the dream, the 3DS is weaker than the Wii, and so is the N3DS which is practically double the processing power of the original 3DS (so about 1319.36 DMIPS, less than the Wii), at least when working in the default 268MHz mode (it can be clocked up to 804MHz on paper, however there are some limitations in reaching that clockspeed).

EDIT: Corrected my own derp, the N3DS is weaker than the Wii, I accidentally compared it to GC's score. Apologies, it's a bit late.

Before someone accuses me of using an obsolete benchmark, at least it's a benchmark, not empty words - it's a sample of one versus zero samples. A difference of over 60% cannot be made up with fancy tricks - stop living the dream, the 3DS is weaker than the Wii. The N3DS is beefier on paper, but it's also multicore which entails performance loss in real-life applications, plus the GPU is weaker. On paper though, it's 3DS > Wii > N3DS as far as the CPU is concerned.

But is it strong enough to emulate PS2?

 

[Foxi4]

No, but it's good enough for the PS5 and the Xbox 720.

Next he'll be telling us that the 3DS is faster then the Wii U because it uses PPC.
