LED OCD isn’t a tricky install, really! It’s unplug and replug, then play
You can fettle it to your hearts content, but will work nicely out the box.
All my games use them, and I’m stupid.
I’ve posted about this many times elsewhere on here, but I use standard Comet 2SMD frosted Sunlight LEDs.
Only use the LEDOCD if you hate blinky bright inserts and potential ghosting. If you’re not sensitive to it, and many aren’t, then get the non-ghosting versions of the LEDs I mention above and sod the LED OCD off.
