See that dodgy looking "Great Escape" game on the right. I can't find any information on this game. I thought it might be an Australian only cart release (all of the Australian made games were on tape or disk as far as I knew) There is an entry at smspower for an unreleased Othello Mulitivision game "Great Escape 2." Don't know if it's related or not.
That logo almost looks like Great Escape 2 or "Great Escape Squared" Bit of a dodgy photo. It does look like a smaller cartridge than the rest of those SG-1000 carts though... I'm not sure if that was the case with Othello Multivision branding. There's not much out there on the net. When you get these, do the world a favour and provide Sega Retro with some scans of those cartridges. They could come in handy.
