I love Retroarch, but something that always bothered me is that 6-button users are treated as second class citizens. Of course you can create core/game specific remaps, but sadly there are no device specific remaps. When you create a remap that works well with a 6-button fighting/Saturn gamepad or an arcade stick, it will suck with a 4-button gamepad, and vice-versa. It's impossible to create a single remap that's perfect for both 4-button and 6-button gamepads. I had to do something to avoid remapping every system or game, every time I want to play with a different controller. This bash script will launch Retroarch with a different configuration file depending on the vendorid:productid of the first connected joystick (js0). Useful if you need to use different joysticks with different remaps. Remaps for 4-button joysticks and 6-buttons joysticks can finally be completely separate. Hello Sega-like/Saturn/6-button/arcade stick users!
