Context: I am on a personal agenda to backup all my games myself. In this search I landed on the Open Source Cartridge Reader (OSCR) it was expensive so I held off until a few months ago when I could finally afford it.
When I got it, I also bought every adapter I needed including the Virtual Boy one, which comes as a Kit. I didn’t think it looked bad, which is why I ordered it. But I held off on making since I started getting cold feet.
Today however I got the courage to try and… it was awful. 60 teeny tiny pins needed to be aligned and individually soldered. It was setup so a skilled micro solder could doing the job in an hour or so… it took me 4 hours and scouring the floor finding pins which fell. Let alone unclogging holes which were accidentally soldered.
However after testing my patience and redoing the last step 3-5 times. It works!!!!!!!!
Now I can play Jack Bros without a VB, and Viper on 3DS is amazing.
Shoutout to Save The Hero Builders. I got everything from them and they were extremely helpful with a noob like me.
Most ready to solder tin sold has a flux core. Meaning you don't really need flux, that is, if you do it the way the original commenter did said.
Another thing that can help is a soldering iron that doesn't take 15 minutes to heat up. If it takes 15 minutes to heat up, there is no way it can transfer enough heat for more than a few pins, as the iron will cool down too much to get a decent joint.
