Majesco's Genesis 3 (single-chip and dual-chip versions) retains the Mode 4 support but has the Master System compatibility removed from the bus controller logic. This renders the Power Base Converter or any other adapter useless. 68000 software can still enable and use Mode 4, however.

In July 2008 the Mega Drive Twin Pad Player by the Chinese Sega licensee AT Games went on sale. It is a 32-bit ARM CPU based hardware emulating a Mega Drive. It has 20 built in games, the same as those included to the aforementioned handheld. The unit comes with two 6-button controllers, a PAL/NTSC switch, composite video and mono sound. Additional "RedKid cartridges" have been announced but not yet released. Whilst it claims to be able to play all original Mega Drive but source have confirmed that several games do not play without sprite issues, sound distortion and multiple other issues. And some games fail to play at all due to the later region lockout chips.[71]
