General / Hidden Key Combo to Show Extended System Info (>= 3.15)

« on: May 25, 2020, 02:38:34 AM »

PSVita Extended System Information on FWs >= 3.15

There was a key combination that showed extended system information in the Setting app, however it is believed that it was disabled in newer firmware due to hackers.

When reverse engineering the Setting app out of curiosity, I found the new key combination for firmware >=3.15.

First navigate to the System Information section in the Settings App, then perform the respective Key Combination:


* Old Key Combination (3.15 <)
1. Hold L+R+Digital Pad Left button+Digital Pad Square button
2. Wait 5 seconds
3. Release 4 buttons and press Start and Select button

* New Key Combination (>= 3.15)
1. Push Left Analog Stick Up
2. Hold Left Analog Stick Down
3. Hold R trigger
4. Press Digital Pad Up button
5. Release Left Analog Stick Down
6. Wait 5 seconds
7. Release R trigger
8. Press Start and Select

* Notes
Old Key Combination can still be used with 3.60 if some debug flags are enabled

PS Vita / [Release] noASLR

« on: April 25, 2020, 08:05:32 PM »

A plugin to disable the PSVita Address Space Layout Randomization (ASLR)


Usage:

• Add noaslr.skprx to your config.txt and reboot.
• Most modules map to a fixed address, making development easier
• enjoy

download : https://github.com/CelesteBlue-dev/PSVita-RE-tools/tree/master/noASLR



Notes

All modules loaded after noASLR will be loaded without ASLR.

If not using Enso, everything except shared modules will be loaded without ASLR

The OS allocated extra memory for ASLR, so using noASLR allows the developer to use more memory.
