I think it's very possible to do it in the Gens emulator. The emulator can run lua code and I think it can read the buttons pressed. Then I think you just need to paint some image of a joytick sega genesys and paint the color on the buttons that are pressed. I think I could take a look.
Some Zamasu's quotes: - When I was invited to this place, I thought you would teach me about justice. However, does the justice of the gods not only pass by to observe? - Every time I am attacked, I enjoy my immortality.

Really ? I would be grateful, as I do not understand anything about Lua script, but I love these controller inputs on the screen.

I created a prototype with the buttons: up, down, left, right, A, B and C.
require "gd"

joysimg = gd.createFromPng("segajoystick.png"):gdStr()
joysw = 120
joysh = 64

transp = {0,0,0,0}
btnpress = {0,0,255,244}

gui.circle = function (x, y, r, fill, border)
	fill = fill or {0,0,0,0}
	-- Fill
	for xr = -r, r do
		yr = math.sqrt(r*r - xr*xr)
		gui.line (x+xr, y-yr, x+xr, y+yr, fill)
	end

	-- Border
	border = border or fill
	yd = 0;
	for xr = -r, r do
		yr = math.sqrt(r*r - xr*xr)
		gui.line (x+xr, y-yr, x+xr, y-yd, border)
		gui.line (x+xr, y+yr, x+xr, y+yd, border)
		--if (math.abs((y-yd) - (y-yr)) > 1) then
		--	gui.line (x+xr, y-yr, x+xr, y-yd-1, border)
		--	gui.line (x+xr, y+yr, x+xr, y+yd+1, border)
		--else
		--	gui.pixel (x+xr, y-yr, border)
		--	gui.pixel (x+xr, y+yr, border)
		--end
		yd = yr;
	end
end

gens.registerafter(function()
	gui.gdoverlay(10, 223-joysh-10, joysimg, 0.9)

	local buttons = joypad.get(1);
	if buttons.left then gui.box (10+15, 223-joysh+21, 10+23, 223-joysh+28, btnpress, 'white') end
	if buttons.right then gui.box (10+29, 223-joysh+22, 10+37, 223-joysh+29, btnpress, 'white') end
	if buttons.up then gui.box (10+23, 223-joysh+14, 10+30, 223-joysh+21, btnpress, 'white') end
	if buttons.down then gui.box (10+22, 223-joysh+27, 10+29, 223-joysh+35, btnpress, 'white') end

	if buttons.A then gui.circle (10+81, 223-joysh+34, 5, btnpress, 'white') end
	if buttons.B then gui.circle (10+93, 223-joysh+28, 5, btnpress, 'white') end
	if buttons.C then gui.circle (10+107, 223-joysh+23, 5, btnpress, 'white') end

end)
This script require "gd" library that gens emulator have in gens-lua.html an explanation to how to install. I use this joystick image, download it to run the script correctly and move it to gens emulator executable directory. Just is a test script, can be better

Movable, more buttons. Download pad.lua
Language: lua

Nice, you can do with that picture:http://genox6.deviantart.com/art/Mega-Drive-Genesis-2-6-Button-Controller-Vector-661885102 Can you put the joystick on the black screen?

subzero13, you are graphic designer? Because that image is great, but it would be better if its size is 120x64, I try to resize it and it lose much the textual detail. EDIT:

That is not possible because the black screen is not part of the drawing element of the emulator, even thanks to the feos's script when i moving the joystick toward the black part is lost. Or well, I do not know if someone more experienced of the site knew something about it.

Just put gui.box(0,0,320,224,"black","black") before gui.gdoverlay().

Now the screen is all black, is it better to leave the control on the "black border" of the screen?
