Fixed the way shared fb is swapped. SceShell overlay shoud work properly now.
Framebuffer swapping in libvita2d_sys is now performed automatically. vita2d_swap_buffers() does not exist anymore.

PS Vita / [Release] libvita2d_sys - libvita2d for system mode applications
« on: February 16, 2020, 10:59:11 PM »
libvita2d_sys is modification of libvita2d with new features and support for "system mode" applications.
Exclusive features of libvita2d_sys:
- "system mode" that actually works.
- support for custom display resolutions, including 1280x720 and 1920x1080 (with Sharpscale https://forum.devchroma.nl/index.php/topic,112.0.html) or 1280x725 and 1920x1088 (without Sharpscale on PS TV).
- Hardware decoding for JPEG textures using Codec Engine.
- Supports loading textures using FIOS2 overlay (for example, directly from PSARC archives).
- Supports GXT textures.
- Extended PVF functionality.
- More coming soon!
Download suprx module version of the library: https://github.com/GrapheneCt/libvita2d_sys/releases/tag/v1.0

Reverse Engineering / SharedFb and sceGxmInternalForVsh sample
« on: February 09, 2020, 09:58:39 PM »
This sample demonstrates how to use shared framebuffer and initialize GXM in PS Vita applications running in system mode: https://github.com/GrapheneCt/SharedFb-PSV
If you have been using NoSharedFb plugin, unistall it before using this application.
It draws squares moving from top to bottom of the screen. Color of the squares will be green if GXM was initialized successfully and red if initialization failed.

Reverse Engineering / Main - background application pair
« on: February 01, 2020, 12:14:42 AM »
This background application sample works in the same way as Skype application: https://github.com/GrapheneCt/BG-App-PSV
SceBgAppUtil is used to manage BG application state from main application and SceNotificationUtil is used in BG application to send custom notifications.
Notifications from BG application can be enabled/disabled in Settings->Notifications. BG application can be restared from main application once it finished working (after the 20sec notification).

PS Vita / [Release] TransparentImpose plugin - makes impose menu transparent
« on: January 23, 2020, 02:02:20 AM »
Plugin for PS Vita that makes impose menu (the one that appears after long PS button press) transparent.
This plugin doesn't work in system applications (exceptions are Videos app and Package Installer).
Install under *main
How to set custom transparency value
Using Vitashell, create config file: ur0:data/trimpose.txt. Edit this file and enter your transparency value. Valid values are in 0-255 range:
255 - 0% transparent . . . 0 - 100% transparent
Values below 30 are not recommended.
Reboot is required to apply changes.

Reverse Engineering / Re: AVContent.db values for ATRAC9 files
« on: January 18, 2020, 01:04:39 AM »
Some more information:
1. Maximum ATRAC9 bitrate supported by PS Vita is 192kbps.
2. By default, ATRAC9 have limited band (all frequencies higher than ~18kHz are cut). To bypass that and achive highest sound quality possible, use -nbands 18 when encoding.
Quality and performance comparision:
1. MP3 320kbps: cuts most of the audio information higher than 16kHz, file size 9.72Mb, core load during playback ~50%
2. ATRAC9 192kbps -nbands 18: keeps everything up to 24kHz intact, file size 5.83Mb, core load during playback ~40%
