Snatcher (Sega CD) - native Linux / SteamOS port (static recompilation) - work in progress

The game is NOT included. Put your own disc image of Snatcher (Sega CD, US release
T-95035: the .cue file and its .bin) next to the snatcher program or in the "game"
folder, then run ./snatcher (or ./snatcher /path/to/image.cue).

Steam Deck: in Desktop Mode copy this folder somewhere (e.g. ~/Games/snatcher), then
"Add a Non-Steam Game" in Steam to play it in Game Mode. It needs only SDL2, which
SteamOS has.

Controls: d-pad / arrows move, A or C/Space select, B or X cancel, X or Z draws the
Blaster, Start / Enter. F11 fullscreen.
Not done yet: settings menu.
