0606 Build

This article has just been started and needs the article basics added. Help us out and add them. Notes: A lot of things need to be added, some final screenshots to compare with the prototype, organization, etc.

This is a sub-page of Proto:Sonic the Hedgehog 2 (Genesis).

The 0606 build of Knuckles in Sonic 2 is the second known build of Knuckles in Sonic 2.

This build is the first one to implement the "Knuckles in" banner.

This prototype, along with the rest of the builds except the 0524 prototype, is a dump of the Sonic & Knuckles UPMEM chip. To play it, it must be attached to the beginning of a Sonic 2 ROM. Merging these two ROMs emulates the use of Lock-On Technology. The 0524 prototype is the only prototype that can be played individually.

Differences#

Title Screen#

The title screen has been updated to how it looks in the final build. Now featuring branding for "Knuckles The Echinda In Sonic The Hedgehog 2" and then the usual title screen design up to this point.

0524	0606 onwards

Notable glitches#

Transformation bug#

Whenever Knuckles attempts to transform into Super Knuckles, he will freeze in place midair, very similar to an infamous bug in regular Sonic 2 where Sonic freezes in place when attempting to transform into Super Sonic past the signpost. Unlike the signpost bug, Knuckles will still lose rings as if he were Super, and will remain frozen in place when he runs out.

Missing objects in Casino Night#

Almost every object is missing from the start of Casino Night Z1 and Z2.

Different Chemical Plant layout#

There would normally be 2 ring monitors and one extra life monitor here
