The Game.com Sonic Jam is not actually a port of the Saturn version, but rather just a collection of levels inspired by Sonic 2, Sonic 3, and Sonic & Knuckles mixed with bleepy music, ugly black-and-white graphics, inexcusable bugs, and an abysmal framerate.

In other words, it ranks up there with Sonic '06, Sonic Genesis, and Sonic Boom: Rise of Lyric as being one of the worst Sonic games.

"No Lock On"

Presumably, Sonic & Knuckles would have had support for "locking-on" the Sonic 2 and Sonic 3 cartridges for new content, similar to the Saturn version. This would be the icon shown when playing Sonic & Knuckles by itself.

Misplaced Rings

In Act 4 of Sonic & Knuckles, a couple of rings which were meant to be placed in a loop are shifted slightly to the right and up of their intended positions.
