PSP News - Public Discussion - Emulation

[kiariki]

The ARM7 is mostly used for sound, touch and wifi. Many games would be playable without those features. It's far more important to emulate the ARM9 efficiently. Emulating some DS games at 30 FPS on a PSP is entirely feasible. The hard part is finding someone with the time, motivation, desire and skills to make it happen.

I doubt games will boot without at least tricking them that the Arm7 is there. :/

Exophase believes it can't be done
But why?? WHY??? We've seen THINGS and THINGS!
We SEE IT EVERYDAY!!! Things tagged "IMPOSSIBLE", YET HAVING THEM ON OUR PSPs RIGHT NOW!!!!!
Like gpSP, and Daedalus, and the custom firmwares!
I told it before, what I believe is that we NEED another genius to make this happen.
And some people pointed that there's no need to have a DS emulator cause it won't be fun. OH YEAH????
AND WHAT ABOUT PEOPLE THAT ENJOY THE DS' SINGLE SCREEN AND GAMES THAT DON'T USE THE SILLY TOUCH SCREEN??



Oooooooooooohhhhh. I'd give ANYTHING in this UNIVERSE to see Shining Force III booting on my PSP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! EVEN IF IT WAS AT 1 FPS!!!!

What if we ignore the sound and the second screen (the touch one)?
Will we gain any speed with that?

You? Again?

A lot of people said that it's not possible. Get it over yourself.

Like gPSP? Yeah, but that was possible. Now there's that little thing that the creator of gPSP said that this is not possible. Daedalus is a great work, but we're talking about MIPS. DS has two ARMs. Doing emulation over differents architectures is a LOT consuming.

Custom Firmwares are not that much of tech-magic, they don't do something so absurd, hardware-level.

And, 80% of DS games use touch. You'll lose great games like Trauma Center.

So to all the people that want to play free DS games on their PSP, get over it. Buy a DS. A lot of people bought it. And if you're that of a cheapskate, and don't want to buy original games, get a flash cart.

But stop ranting about full-speed DS emulators without sound, wifi and touch.

and 70% of those touch screen games suck

im geting a DS now so it doesnt matter to me

I've had an Idea for a while (hope some of you coders are interested) for a program for the PSP....If I knew how to do it It's what I'd be working on. I've always thought that it would be great if there was a way to send a file (besides a picture) to another PSP via WIFI. If someone was to combine a file browser program like PSP Filer with WIFI connectivity, it would be great to transfer files between two PSPs without the use of a PC. I got this idea because I go to my bro's house sometimes and he might want a file on my psp but he does'nt have a PC, and I thougt...It would be badass if there was a way to send the file to his PSP through the WIFI connection...Well that's my idea. Hopefully I can inspire someone to go with it...Until next time...Later...:thumbup:

this doesnt have anything to do with the topic.
and irshell can transfer anything from psp to psp through wifi.

And I bet with the extra RAM on the PSP Slim it'd go really super fast too!!1! LOL :thumbup:

No.

For the love of god, will people stop bringing up the two DS CPU argument with out reading my post.

N64 yes also has two cores running (the RCP is another mips processor with a vector COP2). Yet thanks to the wonders of UltraHLE, most emu (including daedalus) HLE the RCP insted of LLE (low level emulation) it.

The same most likely could be done with the Arm7 in the DS. Why? Because it can not run custom code in comercial games. The Arm7 purely runs off SDK libs to handle some task like Audio processing, Touch Screen, Wifi and a few others.

---------------------------------------------

Another point, people for the love of god. Go freaking replay your DS games. You would be shocked how many of thoes "Touch Screen games" actualy are playable with out even using the touch screen. Even titles like Phyonix Write dont require you to use the touch screen to play.

The problem lies in the CPU. Both N64 and PSP are MIPS based, while the DS is using two ARM processors which is totally different.

That would hinder emulation no doubt. But the PSP has a much higher overhead than the DS. Two ARM processors running at a combined 100 MHZ... The PSP can run at 333 MHZ, allowing it to handle each DS CPU's instructions each clock cycle and still have another 100 clock cycles to handle other things (in a perfectly optimized environment... which may be impossible...)

The hardest hurdle I see is figuring a good way to emulate a touch screen. Analog would be the best bet, combined with maybe the X button. But that depends on the game (if some games use the touch screen and buttons).
