PPSSPP Symbian Port

[Minamoto-kun]

According to my observation, the reason was not the GPU to ...a simple 2D game, weight 60 MB (Mystic Chronicles) very, very slow ((...For example, the game weighing 1 GB (Hexyz Force) a very beautiful 3D, is wonderful. ...CPU emulation of PSP is difficult, probably.

[xsacha]

PSP has a 333MHz MIPS processor. Emulating it with only 680MHz ARMv6 will be a slow experience considering all the extra overhead of emulation. The 1300MHz version is much faster and can play quite a few more games, but it is still emulation.
I don't think I can make those games go any faster without 'removing' some of the emulation. That is, disabling things as a speedhack or detecting large sections of MIPS code that could be done differently.

in PPSSPP 0.9.9.1-112 now exit immediately and loads games faster! thanks a lot ...But a small incident of ...In the emulator of ...Where animation is set against the backdrop of ...Look please ...Colors broke. ...Blue in green bands.

I think the colour break is due to other work going on in the emulator. Hopefully it resolves itself. They are working on adding DirectX9 as a video backend.

I was able to achieve a stable full speed (100%) and, with the help of "Timer Hack" and CPU frequency in my favorite game, but the sound has become corrupted and is behind the game. it cannot be listening to ...is it possible to do,to "timer hack" toting the sound for the video?.The sound did not lag behind?

The sound code is a little buggy, unrelated to timer hack or anything. It may be best just to turn off sound if that's acceptable.

I never figured out why sound code doesn't work

[xsacha]

Oh right. Your screenshot shows 16-bit colours. Again, probably something that will get fixed up soon-ish.

For sound, I was looking at getting SDL audio for Symbian but it's fairly difficult to find.

nfs most wanted 1-5-0 runs at full speed(except for small lag) cpu cloak =25
xsacha,what does texture scaling do by seting it to nearest?

[xsacha]

It's the filter applied when you scale the textures (make them larger than normal size). Nearest would mean 'nearest neighbour', so it smooths the texture based on the surrounding pixels.

what happened with the option to change volume in latest builds?
Btw. FF III is running at full speed with good sound (Nokia 603)

ase5530, on my 701 ff3 is running bad. I have missing textures, with 15 fps on world map and some lags everywhere. Sometimes crashes to desktop. With what settings u have fullspeed?

Final Fantasy 3
Use Non-buffered rendering
Enable "Lazy Texture Cashing(speedup)"
Spline/Bezier quality--- Low
Disable I/O on Thread
Enable "Disable slower effects(speedup)"
Frameskip Off
Autoframeskip Enable
Other by default
in world map Lag in 15-18FPS and in city 10-12FPS but in the cave,forest,in battle 25-30FPS...Texture normal,not broken,not crahed in home screen...I have Nokia E7...

sound in build 112 and 135 scare buggy...In 49 build good sound

Thank you Minamoto-kun.
With no buffered rendering mode i can't see on-screen controls. And when i enable autoframeskip i have fullspeed most of time with buffered rendering. But with frameskip i have lags with sound. After ase5530 post i hope for fullspeed without frameskip, buy thank you anyway. Now i can play without lags.

[ase5530]

buffered rendering
simulate block transfer
force max 60fps
hw transform
sw skinning
vertex cache
lazy texture catching
disable slower effects
timer hack

audio on

fast mem
respect fpu rounding

- all those enabled other settings disabled cpu clock default
- frameskip to 1 helps (exteriors)

The volume settings have been removed since v0.9.9.1-13-g5f8f363

I dont have a symbian device, but anyway: Awesome work!
