Hatsune Miku: Project Diva Extend

[gluemchen]

Works flawlessly. Only issues are slowdowns and sound issues.
Other than that worked very well. I used a build from 29th of Oktober.

The one that had these changes in place.
PPSSPP Git Changelog:
* Fix project and .rc so it builds with VS 2010 Express, thanks Darth1701. Plus logging tweaks.
* Merge pull request #102 from tmaul/master
reduce the number of errors in sceRtc.cpp
* 9999 is actually the maximum year as verified on my PSP
* reduce the number of errors in sceRtc.cpp
* Buildfix (?)
* Warning fixes etc
* DXT textures now mostly working-ish (work left to do on alpha for DXT3/5)

I used windows 7 x64 to run it. Great job sofar.

Oh o,o are you serious o;o yes!!! Project diva is the only game I want to run on my Xperia play

Since 1 ând 2nd aren't working I guessed extend wouldn't work ahah XD

Picture from my Xperia play game running at maybe 5fps ahah

Buffered rendering is needed

Nice find

I do not know what differenciate these versions. The games seem to be using pretty much the same engine. Extend is the only one of the 3 games that work. Project Diva and Project Diva 2nd crash right away. Weird that Extend works without flaw. Man this Emulator has some serious Horsepowerr compared to it`s Java counterpart.

works on android too

if emulation with buffered rendering disabled could be perfected this emulator could very well exceed the one on the vita.
buttered rendering unfortunately renders the game at 272p like the psp and vita do, but if it's disabled the game runs at the host's native resolution.

here an example of how the game looks like at 720p in the few frames that do show properly with buffered rendering disabled:

that almost looks like dreamy theatre quality to me.

there is a small issue with the game though: strings are thrown in the blender.
the text on menu items gets randomly replaced with different text, or a blank space.

EDIT: it seems the pc version does run at a higher resolution with buffered rendering enabled.
this game looks surprisingly well at 1080p.

I've made some profiling to see what's missing for a good framerate. Main bottleneck is the MIPS. It'll need to support 10+Millions of instructions per frame.

For one random frame, profiling for the function searching the instruction :

Code:

MIPSGetInstruction: 733.220 ms, call : 12366916

Then for each different instructions executed :

Code:

I'll look forward to see how this will be optimized in the future.

lol xD

I think they are working on the jit so maybe this huge need will change

(jit will probably not be available soon so don't ask about it xD)

[Henrik]

There's a working basic JIT for PC already, but currently it crashes on the slightest memory error

I probably wont have time to do the ARM JIT until January though, I have a busy December and doing a JIT almost requires a nice big chunk of uninterrupted time...

While making the save system, I just found that the text in the menu is totally wrong. Don't know why but the japanese text is somewhat random

[cloud1250000]

Awesome save system *~*

[thedicemaster]

as i mentioned before, it randomly shuffles all text.
I found out when one of the pause menu options was BPM 160
sometimes it also loads nothing when there's supposed to be text.
