If you're just getting into Game Boy modding then I highly recommend starting out by reading ASM's "Game Boy Modding Guide" found here:
http://chipmusic.org/forums/topic/6324/ … ing-guide/
There are many tutorials for many different mods all over the place. My plan is to write up tutorials for mods that I don't see guides for quite as much and update this post whenever I write a new one.

START PEDAL FOR LSDJ
For starting LSDj without ever having to touch your Game Boy you can install a jack that is wired to the start button.
This is practical for playing live shows where your hands may be full with something like a guitar.
All you need to do is follow the 2 traces of the start button back to where they become a bit wider(use a razor blade to scrape off the solder mask(coating over the copper traces)).
Solder two wires to these newly exposed pads.
I recommend using Kynar 30AWG wire and securing them with just a small dab of hot glue.
Wrap them as pictured so they are not in the way of the button pads(you could also run the wire that is right above the start button straight up through the opening in the PCB that has a capacitor).
Using a panel mount 1/8" jack hook up the wires to pins 1(left/tip) and 3(ground/sleeve) for a stereo jack. A mono jack will only have left and ground pins which would work just fine. You can purchase 1/8" jacks on their own or prewired right here: http://thursdaycustoms.bigcartel.com/pr … -sound-kit
It does not matter what order these are in as you are just making a loop.
You will need a keyboard pedal with an open circuit something like this would work just fine:

This particular pedal has a switch for open or closed circuit.
Open up the pedal and remove the 1/4" cable by heating up the solder on the pads where it is connected.
It will likely only have 2 wires from the cable connected to the switch.
Wire these up to another 1/8" jack in the same way as the first one(pin 1/left/tip and pin 3/ground/sleeve).
Solder this jack to the exact same pads that you removed the 1/4" cable from.
You will likely be able to just mount the 1/8" jack in the hole where the original cable was.
Get yourself an 1/8" audio cable(mono or stereo) and try it out!

There seems to be a lot of different information about link cables and link ports on the internet. I came up with this handy like image to hopefully clear it up. Let me know if you think I should add/change anything!

Prosound mod tutorial. While this tutorial is geared towards the 1/8" mod is has some good information that applies to all prosound mods such as pre and post mot installation:
