PS Vita / Re: [Release] Sharpscale - native 960x544 HDMI output for PSTV
« on: April 02, 2020, 03:36:30 PM »
I don't think 1920x1200 is possible because of hardware limitations.
We invented "Rev ur engs"

PS Vita / [Release] Sharpscale - native 960x544 HDMI output for PSTV
« on: April 02, 2020, 06:29:27 AM »
Sharpscale is a PSTV and PS Vita plugin that changes the framebuffer to display scaling method to provide a cleaner and sharper image.
This plugin is the only method to obtain native resolution video capture with accurate colours at 60fps. A hardware capture kit for the Vita was previously available from Japan for $450 USD, but due to changes in Japanese laws, this is no longer available.
Download
Usage:
Sharpscale can be configured to different scaling methods.
Scaling Modes:
- Original: system default
- Integer: integer scaling while fitting inside the display, for general use with bilinear filtering off
- Real: no scaling, for video capture
- Fitted: non integer scaling fitting exactly inside the display while preserving aspect ratio, for media use with bilinear filtering on, or PS1 with bilinear filtering off
PS1 aspect ratio:
- Pixel: aspect ratio of the framebuffer is retained
- 4∶3: aspect ratio is forced to 4∶3
- 16∶9: aspect ratio is forced to 16∶9
Scaling algorithm:
- Point: nearest neighbour
- Bilinear: bilinear interpolation (system default)
In Adrenaline, set graphics mode to original in Adrenaline settings.
Unlock framebuffer size:
- On: allow framebuffers of sizes 1280x720, 1440x1080, and 1920x1080 to be used
- Off: system default
Installation:
Configuration:
Use the provided configuration app to change settings instantly without needing to close the foreground application or needing to reboot.
If the config app crashes on startup, follow these steps:
1. Use the plugin and config app attached to this post
2. Ensure that the plugin is loaded. It will be immediately noticeable on startup if it is loaded.
3. Disable plugins for the config app by adding the following line
before this line in the taihen config.txt

PS Vita / [Release] PSOneScrot - take proper PS1 screenshots
« on: March 25, 2020, 10:00:24 PM »
The usual way of taking a screenshot with PS+Start does not work for PS1 games. We have created PSOneScrot (PS1 Screenshot) to fulfill this feature which has been sorely lacking.
Download
How to use:
1. Open settings in the quick menu
2. Open official settings if using adrenaline
3. Select screenshot
Video instructions:
Bilinear filtering:
This option will affect the resulting screenshot and is the only graphical option that affects the screenshot.
This option is normally hidden on the PSTV but will be enabled with this plugin. Bilinear filtering has no effect on the HDMI image output.
Installation:
Install under *KERNEL for example

There may be a few errors encountered when using GhidraVitaLoader
1. Conflicting instructions
This is caused by ghidra's auto-analysis thinking NIDs are code.
Go to the address indicated on the error messages, select the code section, right click, and click clear code bytes. Then run VitaLoader again.

PS Vita / [Tutorial] Hatsune Miku Project Diva f 2nd savadata and DLC region conversion
« on: March 05, 2020, 08:28:04 PM »
Savedata region conversion
This is useful if you started on the US version but want to use piapro or if you just became a bigger weeb since the time you started playing. This process won't transfer your network profile nor the edit data. Trophies are shared so there are no problems there. If you started on the EU or AS versions they probably can be converted in a similar process, but the offset might be different.
1. Take your savedata at for example ux0:user/00/savedata/PCSE00434/MAIN00/SECURE.BIN
2. Decrypt with vitashell or psvpfsparser
3. Remove 0x370 bytes starting at offset 0x2EDF0
4. Launch the JP version and create a save in the slot you want to put the converted savadata to
5. Put in the converted savedata with open decrypted in vitashell at for example ux0:user/00/savedata/PCSG00205/MAIN00/SECURE.BIN
Don't know what's suppose to go in those 0x370 bytes but I looked at a few different saves and it's all zeros with a large range of zeros that precedes it. Included below is a python script to do the trimming automatically.
DLC region conversion
Now you may want to do this because NPS does not have all the DLCs for the JP version. Simply decrypt the US version DLCs with psvpfsparser and install with repatch. Make sure you remove sce_sys. PVs won't work but the only missing PVs are the AR PVs.

Reverse Engineering / Dumping addcont IDs
« on: February 08, 2020, 04:30:15 PM »
Logs calls to sceAppMgrDrmOpen to stdout or file. To capture stdout, use PrincessLog or PSMLogUSB found here. File log is recorded at ux0:/aciddumper.log.
This can be helpful for creating fake DLCs.
This only works when the game calls sceAppMgrDrmOpen which requires one of the parameters to be the addcont ID. If the game calls sceIoDopen on addcont0: then sceIoDread to check for available addcont, then the IDs cannot be acquired.

PS Vita / [Release] Quick Menu Plus - Function and style enhancements for the Quick Menu
« on: January 17, 2020, 11:43:46 PM »
Quick Menu Plus merges Quick Power, Quick Volume, and Rapidmenu, as well as adding new features.
Power off, restart, and standby buttons
Configurable power buttons
Volume slidebar
Faster Quick Menu open time
Custom background styles
Download
Installation
Supported firmware versions:
Retail 3.60-3.73
Testkit 3.60, 3.65
Devkit 3.60
Install under *main of your taiHEN config.
Configuration
Put files in the directory ur0:/data/quickmenuplus to configure Quick Menu Plus.
pushtime.txt sets the Quick Menu PS button push time. Put in the file the desired push time in microseconds. For example, put 250000 for 250 milliseconds. If the file does not exist, the default time is 500 milliseconds.
standbyisrestart.txt sets the standby button to function as a restart button. Put in the file 1 to enable, or 0 to disable. If the file does not exist, the default is enabled on the Vita, and disabled on the PSTV. When this setting is disabled, hold the "Power Off・Restart" button to restart, and press to power off.
bgstyle.txt sets the background style. Put in the file 0 for original, 1 for translucent, and 2 for black. If the file does not exist, the default is translucent. Black can reduce power consumption for OLED screens. The gradient effect is removed in all styles.
