Pretty good episode. Wish you'd had more games on disk to show off, especially ones which made better use of the FM capabilities. Zelda 2 was a fantastic example, but it looks like you guys try to record from hardware, and I know it can be a pain to get hold of some titles.
Also, a proposed episode idea, something that's had info around on the 'net for a long time but could use the quality Game Sack treatment: JPN vs US releases. Dracula 3 (NES vs FC, imagery and audio comparison), Bare Knuckle series (US vs JPN), etc... Stuff like that could make for a cool episode, especially since you guys do a great job with quality video and audio presentation.
