modoru VS reVita

-3.69/3.70 users can still safely downgrade with Modoru

Modoru Vita firmware downgrader (The FloW)

You didn't told what fw you're in but maybe try this https://github.com/TheOfficialFloW/modoru

There's a sticky in this reddit that will help you. Most people either update their firmware to 3.60 or 3.65 for a semi-permanent hack (henkaku/enso) or use modoru on an already hacked vita to downgrade to them from a higher firmware including the latest 3.74 firmware. The link in the sticky https://vita.hacks.guide/ is where to start. If you specifically want a particular system update file for modoru https://github.com/TheOfficialFloW/modoru you can find them here https://darthsternie.net/ps-vita-firmwares/ amongst other places. Please note that some Vita's came with firmware above 3.65 pre-installed. These cannot be downgraded with modoru but you can still use h-encore/h-encore2.

To downgrade: You need Modoru 2.3 (for fw 3.74) https://github.com/TheOfficialFloW/modoru

That's the whole point. You rename the tai folder, reboot and run modoru. It's even mentioned on it's official github.

You need revita plugin

reVita. This is a great plugin on paper and can do the button swap, but there's a caveat. Certain games can have analog stick problems when this plugin is installed, even if disabled for that game. Had this happen to me and heard about it from others as well.

Check out https://github.com/MERLev/reVita/wiki to see what you can do.

Something like revita should work in Adrenaline.

The link I gave you also links to a wiki on how to use it https://github.com/MERLev/reVita/wiki in the navigation menu choose "analog stick" and read up on what you can do.

You can always try reVita and remap the buttons using global or per game configuration.

https://github.com/MERLev/reVita. Let's you swap back and front touchscreens among many other things.

You can get it from github here https://github.com/MERLev/reVita/releases/tag/1.0.8
