I want to start this off by saying if you are new or a novice at soldering, either practice soldering or pay someone to do this for you. That being said, this mod is amazing. The clarity on the screen is great. The VGA output is a nice feature.

Here are some tips:

Read the instructions carefully and don't rely on just the pictures. I made the mistake of removing components by following the pics to find out I removed stuff that shouldn't have been removed. Maybe print them out and have them next to you when you are attempting this.

Get a rework station with a hot air gun and soldering iron that lets you set the temp. You can find these on amazon for under $75 and they usually come with multiple tips for the hot air gun and soldering iron. I recommend setting the temp to 350 C for both. The hot air gun will make removing the components a breeze. I think I did all of the removals in 5 minutes with it on my 2nd board. Other than that, it is your normal, get a nice small tip for the soldering iron, take your time and clean the tip of the iron between wires. Also

Finally, keep some flux and desoldering braid on hand just in case you need to clean up a mistake.

Definitely not easy. My first one took me about 3 hours from start to finish, but well worth the effort.

If, like me, you grew up with the Sega Game Gear and have fond memories of long road trips and Sonic, found your old Game Gear in the attic, went through the trouble of recapping the motherboard to get it working again, - the nostalgic gaming bliss is palpable... But there's no getting around the fact that the blurry screen makes a lot of titles more challenging then they need to be.
Nostalgia could only carry me so far, but this mod is a must have if you are a hard core enthusiast. The color reproduction and sharp screen would have undoubtedly created a black hole from 5-year-old me's mind!

That said, this mod is NOT for the faint of heart. I bricked a GG motherboard during my first attempt. You MUST be confident in your soldering and de-soldering skills, as there are numerous components on the motherboard that have to be removed and resistors that have to be bridged. If you overheat and break off the wrong solder pad... may god have mercy on your soul.

Imagine trying to repair three traces a hair's width in size, a hair's width apart...

The instructions are very confusing as well... honestly they kind of suck. Thankfully there are a few Youtube videos you can follow that will guide you through the entire process.

In conclusion; If you have the skills, this mod is 100% recommended.

If you're new to soldering, either study the Youtube videos religiously and practice with a few easier projects first, or pay a professional to install the mod for you.
