I just posted a test program that will allow a Quadstick running
the current firmware (2328) and with "Boot in PS4 USB mode" turned on,
to directly control the PlayStation Remote Play program for PS4 and
PS5. PS5 games should be playable.
Prior to running it, ViGEmBus must be installed. X360CE V4.x can do that, or you can directly install it from the author:
At this point ONLY 64 Bit systems are supported. 32 bit systems will not run it.
I
will be able to make a similar QSX program for PC games that use the
XBox 360 controller. No more setup of X360CE or other connecting
programs will be necessary.
You just run the program and close when you are done with PS Remote Play.
The EXE is signed, but I would expect SmartScreen to complain about running it until it has "aged" for a while.
First you may see a message like this:
Click on More info, then Run anyway. Expect it to be slow to start the first time as the Anti-virus software analyzes it.
