Glitch from the Sonic Retro boards is doing the porting duties of Sonic Triple Trouble for the Master System. He even has released a beta ROM.
www.mnetcs.com/sonic/sonic_triple_trouble.zip
This is great stuff. There's still some things to correct but the process is going well and the game is playable/completable already.
Working:
* Palette load/fade routines
* Pause button
* Button 1/2 take the place of the GG start button
* Title screen (...ish. See if you can spot the bug)
* Rewrote HUD placement code.
Working but faulty:
* Camera can pass the level bounds
* Problems with camera in SPZ act 3
* Some music designed for GG stereo sounds odd in mono
Known bugs:
* Knuckles object in the intro sequence
* Garbage object on the title cards
* Garbage on the score cards (partially solved now)
* Demo sequences
* Water level in time attack mode
Shibunoa, also from the Sonic Retro boards, is managing the same too with a Master System version of Sonic Drift 2. There's also a beta ROM of this.

Bugs:
- Can't exit demo mode (you have to wait for it to finish)
- Status is shown in the middle of the screen during races
(this requires much hacking to change)
- Some garbage is shown in the top right part of the screen
during races
- Some things look like they're cut in some screens
This happens also because Sonic Drift 2 wrote "useless" stuff
in the parts of the tilemap not shown on screen.
> Bugs due to hardware limitations <
- Can't pause in a race (due to lack of buttons)
- Colors do not appear as they were meant to be often.
Shades are "scaled down" in precision, due to colors being 12bit on the Game Gear
(which has a total of 4096), instead of 6bit as on the Master System
(which has a total of ONLY 64). The difference is obvious. Most things look fine, though.
