My requirements for this project are as follows:

The unit must be able to operate in standalone mode, requiring only a 12vdc input

Optional remote control interface, but the primary control is hardwired

The hardwired control is preferred to be cheap, easy to replace, and be hard to kill (preferably no USB controllers)

Keep the BOM count to a minimum, less parts means it should be less likely to have a failure (in theory)

Be able for a kid to operate it intuiatively

Be able to handle getting power dumped without warning

Resume playback as fast as possible once power is restored

Be able to play games
