PPSSPP A portable PSP emulatorFree & 100% Open Source

Hey what's up guys does anyone heard about PPSSPP emulator the PSP emu?
I've just found out about it today and thought sharing with you.

Quote:

PPSSPP is an open source project, licensed under the GPL 2.0. Anyone is welcome to contribute their improvements to the code, and the hope is that over time this will resolve the compatibility problem.

Fast and portable
PPSSPP is written in C++, and translates PSP CPU instructions directly into optimized x86, x64 and (soon) ARM machine code, using an efficient JIT compiler.

PPSSPP can thus run on quite low-spec hardware, including stronger Android phones and tablets, as long as there's support for OpenGL ES 2.0.

When the proposed ARM HLE support rolls around, we can then build this on the N900 and N9/50

hey, i was going to make a thread about this, haha , but i hope it can be ported to N9, my brother test it on his xperia play, and works quite well...

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

Sweet, I've been waiting for this for a while.
Does anyone know the state of Dreamcast and PS2 implementations ??

PS This is why I like Qt > Java. It runs much faster, on slower hardware (efficiency) and it is just as compatible, if not more when the App is created in C++ first then converted to iOS and Dalvik.

Impressive and it runs at least such "2D" games surprisingly fast already :o

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

Ok just a noob question: haves the psp lover hardware specs than the n9?

2012-11-13 22:44

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

@kanser: The n9 has better specs (quite big difference).
The PSP uses one 333 MHz MIPS32 R4000-based CPU and includes 32 MB RAM. In comparison, the n9 has a 1G'Hz ARM Cortex-A8 CPU and 1GB of RAM. You can read the wiki pages of the two for more info.
However, you can't really compare the two as they are used for different purposes, one is a portable gaming console and the other is a mobile phone. (Other than that, they alsp have diffrent CPU architectures that's why emulation is required).

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

Just by clockspeed alone the N9 is 3 times faster. And remember the architecture and RAM are also faster on the N9. I would say its at least 10 times faster than the PSP.

I don't think the N9 is powerful enough to emulate it properly (compared to like PSX emulator), but even with sloppy coding the N9 can show superior graphics...to that 8 (?) year old device.

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

As a rule of thumb, for a good emulation you need a hardware at least 10 times faster than the emulated hardware if I recall correctly...

Kangal

2012-11-13 23:57

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

That used to be the rule of thumb, doesn't apply anymore.

The software has gotten much more detailed and sophisticated that you need considerably more.

Imagine what its going to need to emulate the PS3, a cluster server computer?

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

Ok, got it compiled for Fremantle. Not yet tested on device. OpenPandora-camp got it already running (rumours), but it is not yet very fast (also rumours) without JIT-support on ARM.

If you want contribute just now you need cmake-2.8.8 (almost trivial to compile). Then check kludge on: https://github.com/hrydgard/ppsspp/issues/347

And then apply these (not yet in issue tracker)

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

I am working on a harmattan port (although I don't have an N9). These are the build errors from Qt Creator - http://pastebin.com/PeP34MSa . There should be an Arm Jit in the next version (0.6) however I don't think it will be smooth on Fremantle (n900) or most of the android phones (except for the very simple games)

EDIT: Ok, I am now here - https://github.com/hrydgard/ppsspp/issues/347

I also tested with qmake for Fremantle. For Settings.pri (otherwise it tries with GL, not GLES)

Code:

-unix:!blackberry:!symbian:!macx: CONFIG += linux 

+unix:!blackberry:!symbian:!macx: CONFIG += linux mobile_platform

And then it ends:

Code:

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

I forgot about this thread - this file should be working (I don't have an n9 to test on). The main Qt guy in this project (xsacha) said he had tested it on his n9 and the problem was that n9's gpu is slow. Hopefully when they implement the arm jit it would get better. This .deb is built by me with qt creator and again - i am 99% sure it should work. Please test :) Download: http://www.mediafire.com/?q36f2ih61osh856

Hey guys,

I believe this is the installable .deb you are looking for ;)

Edit: I put the assets in there as well as a .desktop launchable.

Oh, sh*t. I have forgotten to put the assets.. the .deb is useless. The assets folder should be in the same directory as the executable and the libs should be in a folder called libs ...

Re: PPSSPP A portable PSP emulatorFree & 100% Open Source

Seems ppsspp can't be compiled with gcc-4.2. It uses "-std=c++0x" / "-std=c++11", e.g. code uses 'auto iter' which is introduced in gcc-4.4.

---
So using gcc-4.7.
1) Compile (or package) cmake (2.8.9) inside scrathbox. Install.

2) Fetch code for ppsspp (seems this can't be done inside sb)

Code:

git clone  https://github.com/hrydgard/ppsspp.git

cd ppsspp

git submodule update --init

3) patch
file: Common/Log.h

Code:

#if !defined(_WIN32) && !defined(PANDORA)

+//ucontext.h will be then skipped 

+#define _SYS_UCONTEXT_H 1

#include <signal.h>

#endif

(Reason: some files includes <signal.h> (currently first time is Common/Log.h). Signal.h includes /usr/include/sys/ucontext.h which uses names R0...R10 (registers) which then clashes with names in Common/ArmEmitter.h.
This hack/patch skips loading of sys/ucontext.h (and we seriously hope nothing else will not broke) [https://github.com/hrydgard/ppsspp/issues/347])

4) compile (inside sb)

Code:

mkdir build

cd build

cmake .. -DARM:boolean=ON -DX86:boolean=OFF -DUSING_GLES2:boolean=ON -DHEADLESS:boolean=OFF

make

5) copy to the device
file: build/PPSSPPSDL
directory: build/assets/

I have compiled version git-eb97a3bd15e021789f81bfe5c3eb3be1bb5b7e90 (but haven't tested to run it at all).

I'm working on it for Maemo5. Very recent code needs some tuning, I haven't yet posted them to the authors. And running the emulator stops right to the start:

EGL_BAD_CONFIG (0x3005)
EGL ERROR: Unable to create GLES context!

So it needs some maemo tuning also for initializing GLES.

[EDIT]
Cube test works:

get recent cmake (and cmake-data), e.g from: http://cc.oulu.fi/~rantalai/maemo5/squeeze/repo/

Code:

git clone git@github.com:aapo/ppsspp.git

cd ppsspp

git clone git@github.com:aapo/native.git

mkdir build

cd build

cmake .. -DMAEMO:boolean=ON

make 

scp -r assets/ PPSSPPSDL user@192.168.1.111:ppsspp



On device:

#test intro and main menu

./PPSSPPSDL



#Test demo

wget http://ppsspp.org/files/cube.elf

./PPSSPPSDL cube.elf

Debian package and video will be released soon.

i wrote to developer of ppsspp with question if he can compile application to our n900. he wrote me back:
