Today, we're taking care of this lovely Japanese Master System (MK-2000). Follow along below for a look at the journey to full restoration. 👇 #MasterSystem #Sega

2 / 5

Open it up and naturally it's dusty, so to the bath it is for the shell.

3 / 5

Replaced all the capacitors and reflowed most of the solder joints on the system. Also replaced the voltage regulator and thermal paste. Additionally, cleaned all the connectors and applied deoxit.

4 / 5

Cleaned the controllers as well and then reassembled everything. Looks much nicer now. Time to move on to testing.

5 / 5

Finally, the reward for all the hard work. Playing a bit of Alex Kidd in Miracle World, R-Type, Streets of Rage II and Monster Boy III. Going to apply some protectant and then we're done with this one. 😉 #RetroGaming #AlexKidd #streetsofrage #RTYPE #MonsterBoy

The final details before the sendoff. Wipe with isopropyl and then application of some 303 protectant. #RETROGAMING #Sega #Dreamcast #MasterSystem
