Description

This is a physical edition of the SKBN homebrew game for the Sega Master System.

Specifications:
  • A total of 1736 built-in puzzles of all difficulty levels.[1]
  • 4 themes to choose from (V2, V1, Mac and KSoko)
  • Optional point mode (Simply point where to go using the controller and the game finds the shortest path)
  • Compatible with PAL and NTSC consoles (50 pin / non-Japanese)
  • Also works on Japanese SMS consoles and Mark III using an adapter
  • Compatible with the power base converter (or equivalents)
  • Supports SMS Control pads, the Sports Pad, Megadrive controllers[2] and the Mega Mouse.[2]

The game is sold as "cartridge only", without box nor manual. There is no sticker on the back of the cartridge, and there is a small slot on the top which serves absolutely no purpose (see pictures).

Built using our 4Megabit reprogrammable cartridge PCB.
