Having a little multimeter can help quite a bit. A little pocket one is all you need and you can use it for a variety of things. For someone new at soldering, though, it can help you make sure you don't have any shorts or trace where a lead goes to. Something else you're going to need is a wire stripper and wire cutters. You'll most likely need these for doing the pro audio mod. It'll also help to have some razor blades. There are several videos on youtube on the procedure and it looks like Domz posted a few links.

The biggest thing you'll need is patience. Be careful when drilling holes into the plastic case. I found that it can be fairly easy to crack it if you don't drill it straight. I just learned that one the hard way and decided to buy a step drill bit to make things a little easier with the replacement case I have on oder.

just remember, pliers, rubbing alcohol, q tips, and take long walks in between

yes

the answer to any further questions is probably google

a bit curious. Can an RCA prosound be installed on the same gameboy as a 1/8?

Thank you all very much!

That gives me a little insight. However, as I stated before, I am a noob, and therefore unfamiliar with the 1/8 prosound as well. Perhaps you can elaborate further?

Nonfinite has a pretty good video tutorial explaining how to install the backlight. as for the RCA prosound that's not too bad. that all depends on where you want the jacks. all you do for that is run the shields to ground, and the inside pin of each to the left an right channels that you would normally run to a 1/8th prosound.

I just ordered a few parts to mod my gameboy from Nonfinite Electronics.
a V3 Ultra backlit screen,

a Pro Sound RCA Kit,

and  replacement screen.

I have a DMG-01 model gameboy, and while I have done some research, I'm still a little lost on the modding process.

I already have a soldering iron with a 1 mm core solder, a drill, a tri-wing screwdriver, and a jeweler's Phillips head.

Perhaps someone could tell me....

1:Any additional tools I need.

2:The order in which I should install the parts,

3:Step-by-step on how to do so.

I can't afford to mess this up. I already spent almost a year saving up for the money to purchase these items.
