Sonic NGPC alternate opening

Someone recently came across a beta or possibly store demo for Sonic the Hedgehog: Pocket Adventure for the NGPC. The standard Sonic has long been known to have a debug mode, accessible through button pressed, and people had hinted about seeing an alternate intro - but thanks to this rom being found, you can now view the lost intro. It seems it was just a giant chunk of PCM sound, so was cut for size reasons. It seems to be the announcer from Real Bout, as well. Thanks to Flavor for pointing it out, and the Sonic Retro forums for the hard work.
