I get a lot of garble on the screen or odd references to coins, roms, ram, and such. Whats up?
Didn’t you ever see an arcade game power up at the arcade? When you turn on a real arcade machine, the machine goes through self-tests, diagnostics, etc. to ensure the internals are okay. Some games have a VERY VERY long self-test when they start. Just be patient – it will end eventually. Check the troubleshooting section for more help.
