This seemed a nice place to put this... this post is not as entertaining as the above video, and only covers the Mega Drive/Genesis, but it does have tables!

Tested with: a Shuttle mouse (with a SAT->MD adapter), PAL Mega Drive 2 (revision: VA1.8) at both 50Hz and 60Hz, and a Mega Everdrive X7

Here's a quick overview of the mouse buttons mapping and controller port usage of the mouse compatible games on the Mega Drive, and a few other key details, ordered by release (approximately):

Game	Release	Region	Lockout	LMB	RMB	MMB	Start	Port1	Port2
Marble Madness	1993-08	Japan		Start	Options	N/A	N/A	Player 1 only	Player 2 only
Nobunaga no Yabou Zenkokuban	1993-09	Japan		Click	Click 2	N/A	Start	Works	Works
Nobunaga's Ambition	1994-01	USA		Click	Click 2	N/A	Start	Works	Works
Two Tribes - Populous II	1993-10	Europe		Click	Click 2	N/A	N/A	Works	Works

Fun 'n Games	1994-10	Europe	Yes	Click	Start	N/A	N/A	Pad only	Mouse only
Nobunaga no Yabou: Haouden	1994-02	Japan		Click	Click 2	N/A	N/A	Works	Works
Shanghai II: Dragon's Eye	1994-03	USA	Yes	Click	Click	Click	Pause	Works	No
Lord Monarch: Tokoton Sentou Densetsu	1994-06	Japan	Yes	Click	Click 2	N/A	N/A	Works	Works
Body Count	1994-07	Europe	Yes	Fire	Bomb	N/A	N/A	Works	Works
Body Count	199X	Brazil	Yes	Fire	N/A	Bomb	Pause	Works	Works
Jimmy White's Whirlwind Snooker	1994-11	Europe	Yes	Click	Click 2	N/A	N/A	Player 1 only	Player 2 only
Lemmings 2: The Tribes	1994	USA	Yes	Click	Click 2	N/A	N/A	Works	Works
Lemmings 2: The Tribes	1994-11	Europe	Yes	Click	Click 2	N/A	N/A	Works	Works
Richard Scarry's Busytown	1994-11	USA	Yes	Click	Click	Click	Pause	Works	No
Wacky Worlds	1994-11	USA		Click	Click	Click	N/A	Works	Works
Wacky Worlds	199X	Brazil	?	?	?	?	?	?	?
Cannon Fodder	1995-01	Europe		Move	Fire	N/A	Pause	Works	Works

For almost all of the games: mouse movement is very smooth with my Shuttle Mouse.
Most games only use 2 buttons (left mouse button and right mouse button)
A few make use of the start button (sometimes only to start the game, sometimes to allow pausing in game)
Most games can work with the mouse in either controller port
Some of the USA releases use the middle mouse button, but those games have all 3 mouse buttons mapped to the same action
The Brazilian release of Body Count swaps the middle mouse button with the right mouse button from the European original (and is the only game to use MMB for an alternate function)

The following table lists issues, and other items of note, that I experienced during my testing.

Note: It is possible I have attributed the issues to the wrong item, due to lack of different hardware for comparison, e.g. low sensitivity in Wacky Worlds might not be caused by the game, but my mouse/Mega Drive instead.

Game	Shuttle Mouse	Mega Everdrive X7	Game properties
Body Count	Works	In-Game Menu Issue*	Can choose pad or mouse for single player, no matter which port is used, can use pad or mouse for either player in 2P mode, depending on what is plugged in to each port
Cannon Fodder	Works	In-Game Menu Issue*
Dominus (Prototype)	Works	In-Game Menu Issue*
Fun 'n Games / Fun 'n' Games	Works	Works	Must use pad in Port 1 and mouse in Port 2
Janou Touryuumon	Works	In-Game Menu Issue*
Jimmy White's Whirlwind Snooker	Works	Works	port number corresponds to player number (you must plug mouse in to port 1 to play a single player game with the mouse)
Lemmings 2: The Tribes	Vertical stutters^	Works	Note: Tested with an official PAL cart as well - same issue (Vertical stuttering)
Lord Monarch: Tokoton Sentou Densetsu	Works	Works	Uses awkward tile sized cursor over map
Marble Madness	Works	In-Game Menu Issue*	Designed for trackball mode, increasing trackball sensitivity makes it more playable in mouse mode
Nobunaga no Yabou Zenkokuban / Nobunaga's Ambition	Works	In-Game Menu Issue*
Nobunaga no Yabou: Haouden	Works	In-Game Menu Issue*
Richard Scarry's Busytown	Vertical stutters^	In-Game Menu Issue*	Must use pad/mouse in Port 1
Shanghai II: Dragon's Eye	Vertical stutters^	In-Game Menu Issue*	Must use pad/mouse in Port 1
Two Tribes - Populous II	Works	In-Game Menu Issue*	Designed for trackball mode, vertical is inverted – to use mouse mode: Click globe -> Set option: Mouse X+Y- (click twice) Mouse movement is a bit "laggy" - maybe the game runs at a low frame rate?
Wacky Worlds	Works	Works	Low sensitivity

* Having a mouse in Port 1 triggers the Mega Everdrive X7's In-Game Menu (workaround: Disable IGM or plug mouse in to Port 2)

^ The few games where I list "Vertical stutters" have jerky vertical mouse movement, horizontal movement is smooth (I have guessed the mouse is the issue)

___________
If I ever get any other hardware to test, I'll post the results.

If any one else has other hardware configurations, it would be great to compare and make this data more comprehensive/refined.

You can look at the attached spreadsheet for an editable copy of the above results, as well as my results from running tests 1-10 from gasega68k's development of Wolf3D: wolfenstein 3d demo for sega genesis - Page 26... (read from the linked post onward to follow along)
