Hatsune Miku: Project Diva Extend

[ShadelowStar]

UPDATE October 9th, 2016: A lot of this information was really badly optimized. I'm glad I wrote this still, but a lot of the things need updating.

First of all, my rig is awful, so chances are you can do much better then my settings:
Windows 10, Intel Celeron N3050 (1.6ghz dual core, 2.1ghz turbo), 4GB Ram, 500gb HDD, 1336x768 screen

About Intel Turbo:
Something to bear in mind from my experience is that 1.6ghz out of an Intel CPU on a built in GPU is not enough to run this game. Due to the lack of multi-thread support for the time being, you'll need a much better processor

60FPS:
All the PSP games will inherently run at 30FPS. While it's playable by all means, you'll have a better time trying to get perfects and high scores in a 60FPS mode. However, you may end up reducing your settings in order to get it working.
1: Close PPSSPP, locate the PPSSPP folder on your system
2: Go to the folder: PPSSPP>MEMSTICK>PSP
3: Create a new folder here named "Cheats" (without quotes)
4: Open PPSSPP and goto Settings>System, then Enable Cheats should be turned on
5: Open the Project Diva game you wish to add cheats to
6: Close PPSSPP and go into the Cheats folder you had created. There should be an INI file in there now
7: Open the INI file (Notepad or any text editor can do this)
8: Depending on your Miku title, paste one of the following lines of code below into your INI file.
9:Open game in PPSSPP again, play it, pause, then go into the cheats menu. If the cheat doesn't show up: 1) Make sure the INI file saved and isn't blank. 2) Check and see if you put the right Cheat code into the right INI folder

Texture Scaling
Off for best performance, possibly can make the game look much better if on.
This being set on can cause songs to regularly lag if your GPU isn't capable of the much faster writing speed it's expected to account for. If you suspect lag, play the song again, note where your FPS drops. If it drops on those spots consistantly, then lower or turn off Texture Scaling.

Examples below in the attachments.

Buffering, Anti-Aliasing, and Rendering Resolution

Non-Buffered Mode: Game will automatically render at the highest resolution your monitor is capable of rendering. This can prove significantly faster then any buffered mode, but looks the worst when rendering distant models, and forces the menus and loading screens to flash black regularly.

Quality in Buffered Mode:
No Anti-Aliasing: For sharper character models, use a rendering resolution 1 times higher then your window size (1x Window means 2x Resolution, where 3x window means 4x resolution).
This renders character models without blurring resulting from using Anti-Aliasing, however, increasing the Resolution by one uses more processing power then anti-aliasing the lower resolution.

Anti-Aliasing: As above, but turn on Anti-Aliasing as well. Rendered models will look much better in screenshots and when rendered from farther away, but will slow the game down somewhat.

Examples below in attachments.


General Settings

Throttle: Set a keybinding to Throttle. Use this to dramatically reduce the length of time spent booting or loading the game.

Frameskip: Highly ill advised. Anything below 30FPS will have extreme stutter and constantly drop commands. Set to auto, game lag will be replicated to real-time instead of slow down, but still drops commands badly and harder to feel for, unlike without the frameskip,

Ansioscopic Filtering: The difference between having this off or set all the way to 16x is somewhat unnoticable graphically and CPU wise. You can set it to the max of 16x and leave it there.

Audio Latency: Set to Medium. There may be cases of audio de-sync at Low latency.

Fast Memory: Set to on. Will ignore checks and assume all memory reads are correct. Performance should be increased. Only reason to not use this is if you experience any crashes when using it (likely ones you can replicate), in which case turn it off.

Multithreaded: Turn off. In basically every case this makes the game unplayable with endless frame sync issues.

Cache Full ISO in RAM: Keep off. This allows the game data itself to be read very fast, but everything needs to be written into the memory in the first place. If you're really interested in the absolute most speed, get a 3.0 USB Flash Drive to store the whole game on, maybe even PPSSPP too. If you're on a phone, this is irrelevant because flash memory is far more available and cheaper on phones.

Show FPS/Speed: Very useful for noticing problems. FPS changes sometimes will relate to a stutter in frames, but less so when running 60FPS. If you use the throttle keybind, then speed will tell you exactly how much the faster the game is performing.

(Unconfirmed) I/O on Thread: On and set to Fast. May increase the speed of the game.

(Unconfirmed) Change Emulated PSP Clock: Set to to 333mhz. Possibly increases the stability of PPSSPP. While an oddly low number, this is the power of the PSP and will run games more accurately.
Other possibilities are to run at 222mhz or lower. Game can become unstable if you attempt below this however.

(Unconfirmed) There may be a benefit to Frameskip set to 1 if you are running in 60FPS cheat. The theory stands that the game will either:
1: The game will no longer speed up trying to correct an FPS drop, because it can run at an FPS higher then 30 without issues.
2: When the game lags, the Frameskip will correct it by rendering a half frame, keeping a relative 30FPS.
