[Feature Request] Reenable Guncon support (nuvee plugin deprecation)

[legend800]

Description
Due to this: #3889, USB plugins are deprecated, disallowing users to continue using the nuvee plugin which provides guncon support. So users can no longer use the guncon feature in games and map input to mouse or external guns (aimtrack, sinden, etc.).

Reason
Without this, light games games are basically unplayable as you need to point quickly at things and you just can't do that with a gamepad stick.

Examples
Some example impacted games:

Endgame
Gunfighter
Ninja Assault
Time Crisis Zone
Time Crisis 3
Vampire Night
Virtua Cop
Police 911

Now that the usb plugin is merged, it will be next priority to implement all missing functionality that other plugins would've otherwise provided.

Please be patient as merging plugins is a messy and slow process :)

Dunno if it'll help, but this is the source for the nuvee plugin, if you need hints on how it works https://github.com/mirror/nuvee/tree/master/nuvee_ps2_usb%20-%20guncon2%2C%20keyboard%2C%20mouse/src

Yeah I mean, I don't know how else we can get the word out. Lots of stuff will be moved around and refactored and there will be things that get removed and re-added and bugs to fix.

Unless 1.7.0 fixes a bug for you or you're just interested in helping the team test the dev series you don't need to be using it. This isn't the 1.5.0 dev series where everyone had to use it because 1.4.0 was so far behind. A lot of 1.7.0 has been some fixes here and there and a bunch of merging plugins and redesigning things.

Locking this thread temporarily because people keep bumping it without adding anything germane to seeing it implemented.
