I hooked up all the usual stuff. Batteries, screen… To see if it worked But nothing happened. The unit would not run off the battery it appeared!     But I knew I couldn't just give up. Like Timmy T, I decided to give it one more try…   And there was light. And I saw that it was good. It turns out that I had the cartridge inserted backwards the first time! Ahem.   I had a 2 ½" screen laying around and decided to use it in the SNES portable. But, would it be big enough? I realized I had to test it….  I decided the screen was suitable to my needs.      Designing the System Shape!
