Knuckles in Sonic 2 prototype 0608 for the Sega Mega Drive was released by drx during the February 23rd, 2008 proto release.

This prototype, along with every available build after the 0524 prototype, is a dump of the Sonic & Knuckles UPMEM chip. In order for this build to be playable, it must be attached to the beginning of a Sonic 2 ROM. Merging these two ROMs emulates the use of Lock-On Technology. The Knuckles in Sonic 2 0524 prototype is the only prototype released as a working stand-alone build.

Various differences

  • Level Select is not enabled by default. At the title screen, pressing Up, Up, Down, Down, Left, Right, Left, Right, and then A + Start will enable it. This code is very similar to the Konami Code.
