Wow.

Two videos in a row where I fail to solder a battery holder onto a SNES cartridge.

The next one will be a success.

I promise, or your money back!

There are actually two separate jobs in this video.

First, another attempt at removing and replacing the cartridge battery.

Second, a check of the TSOP40-to-DIP36 adapter I had been using for the SNES flash-memory project.

I found a continuity problem in the adapter, which gave me another very useful thing to fix before trusting it with more programmed flash devices.

Apologies for the loss of continuity.

Electrically and editorially.
