SDL Input Joystick for LZDoom v3.88b (SIJL) for RetroPie

Add support for SDL Input from Joystick in Menus eliminating the need for a Keyboard.
Additionally includes Pre-Configured Joypad Mappings + Raspberry Pi specific Tweaks
NOTE: You must COMPLIE LZDOOM yourself, the Menu Script just helps you load the DIFFs

This isn't really new, it was started a long time ago under this topic:
Zdoom and Gampad Fully Working in MENU with NO KEYBOARD
This is just Updated [rpi_fixes.diff] and slightly tweaked [lzdoom] installer script.

How To

1- Use [lzdoom-sijl] Menu driven Script to assist with [sh/diff] files placement.
2- Compile/Install [lzdoom] from [RetroPie-Setup]:
0ptional Packages -> Ports -> lzdoom -> INSTALL FROM SOURCE
When Compiled from Source [lzdoom.ini] will populate your Selected Joy Pad Bindings by Default

Installation

Can be ran from retropiemenu:

wget https://raw.githubusercontent.com/RapidEdwin08/sijl/3.88b/lzdoom-sijl.sh -P ~/RetroPie/retropiemenu
wget https://raw.githubusercontent.com/RapidEdwin08/sijl/3.88b/lzdoom-sijl.png -P ~/RetroPie/retropiemenu/icons

0r Can be ran manually from any directory:

cd ~
git clone -b 3.88b https://github.com/RapidEdwin08/sijl.git
sudo chmod 755 ~/sijl/lzdoom-sijl.sh
cd ~/sijl && ./lzdoom-sijl.sh

0ptionally you can Add an Entry to retropiemenu [gamelist.xml]:

	<game>
		<path>./lzdoom-sijl.sh</path>
		<name>[lzdoom] SIJL</name>
		<desc>INSTALL/REMOVE [lzdoom-sijl] for [RetroPie].</desc>
		<image>/home/pi/RetroPie/retropiemenu/icons/lzdoom-sijl.png</image>
	</game>

I think I might be the only one using this... but either way...

SIJL has been updated for LZDoom 3.88b.
Added Utilities for xpad Driver trigmapping patch.
The 0lder SIJL Branch for LZDoom 3.87c still available if needed.

@RapidEdwin08 I used it before. Worked great.

Nice to see you updated it to the that version of lzdoom....that I didn't know about. Lol

I'm too busy working on scripts for RetroPie extras. Lol
