There are also several other notable differences when playing these two combined games. Tails has no Hyper form, but the Super Emeralds are needed for him to transform into Super Tails, as the Chaos Emeralds alone have no effect on him.

When these Emeralds are collected, Hidden Palace Zone will become available, and Sonic can transform into Hyper Sonic and Knuckles can transform into Hyper Knuckles. The final boss of Sonic 3 is also omitted for Sonic and Tails.Īfter collecting all the Chaos Emeralds of Sonic 3 a new quest becomes available when entering the first special Stage in Mushroom Hill Zone which allows you to collect seven new Emeralds called 'Super Emeralds'. Once these levels are completed the Death Egg falls off screen intact instead of being destroyed, and then the play continues straight to the levels of Sonic & Knuckles. Also, all of the levels from both games are accessible, starting from Sonic 3. Knuckles is playable in the Sonic 3 levels and Tails becomes available in the Sonic & Knuckles levels. There are several noticeable differences when playing the games combined.

In Sonic Classic Collection, for unknown reasons, the game was renamed to Knuckles in Sonic 3. It acts as one large combined game and all the levels from Sonic 3 and Sonic & Knuckles become available. Kega is not recommended for CD emulation.Sonic 3 & Knuckles is a game that results when Sonic 3 is locked-on to Sonic & Knuckles via Lock-On Technology. While it supports Sega CD emulation, there is notable audio sync issues. Kega Fusion also suffers issues with 32X timing and graphical deficiencies, though does have proper volume levels unlike Gens, which has higher compatibility but has worse sound emulation. However, this can be easily fixed by right-clicking on Fusion.exe > Properties > Compatibility > check 'Disable Fullscreen Optimizations.' On Windows 8.0 and later, an incompatibility issue (related to DirectDraw support in these operating systems being further deprecated) causes the emulator to drop frames, or freeze entirely in the case of Windows 10 and later, when attempting to switch to fullscreen mode. However, it lacks the 32X support that Kega Fusion has. Genesis Plus GX has 100% commercial game compatibility. For this reason, other Sega Genesis emulators have surpassed it in terms of compatibility.

Unfortunately, it's closed source and no longer updated. A high-quality emulator with high compatibility.
