Gunstar Heroes v0.9 GG2SMS Conversion by sdsnatcher 2017-01-12

There are two versions: one with a normal palette tweaked to show all the pixel art details in the SMS, and one that uses the 3D glasses to expand the SMS perceived palette to 261 colors, this making the colors closer to the original GG game.
Removed a software lock that caused trouble to run the game on the Master Everdrive.
Garbage was removed from nearly all screens.
Enabled the left column masking.
The PAUSE button now works properly and doesn't crash the game.
Button-1 of the 1st joypad now acts as START when needed.
Moved the text speedup to the 2nd button.
The 2nd joypad has SELECT on its button-1, and PAUSE on its button-2.
Megadrive joypad support. When one is used, the C button acts as SELECT and the START button will pause the game accordingly, and act as START button where needed. There's no need to use two joypads anymore.
Enlarged screen area.
The Sega logo screen now can be skipped.

But the patch is far from finished and still has some known glitches:

Some elements have an offset when compared to the background. Specially the hitboxes of the houses in the 1st stage and their smoke after they explode, and the plant boss.
Some graphical glitches still occur at some specific points in some stages, notably on the pyramid of the 1st stage, and when almost reaching some bosses.
The larger screen area makes some enemies appear immediately in some areas, like in the 1st screen of the 1st stage, and in the 1st screen of the airship stage.

Due to the persistence of vision, the 261 colors trick also works without the 3D glasses, but some flickering will be noticed.
