OpenSWOS
Sensible World of Soccer, rebuilt in C from the original Amiga game. Same game,
same feel, now on Windows (10 or later), macOS, Linux, the Raspberry Pi and the Amiga 1200,
with online multiplayer.
Getting started
Official downloads: baker76.itch.io/openswos, linked
from openswos.net. Nowhere else is OpenSWOS's own.
- Download it for your computer.
- Install it: a step-by-step guide with pictures.
OpenSWOS needs your own copy of Sensible World of Soccer 96/97 (the PC version from
GOG is the easiest). The
game's graphics, music and teams aren't included: OpenSWOS Setup makes them from your
copy, once, and downloads nothing. INSTALL.md shows you how.

What's in it
- The whole game: friendlies, leagues, cups, the career mode with transfers and
management.
- Online multiplayer: play a friend over the internet (MULTIPLAYER on the main menu).
- Widescreen at any resolution, fullscreen, CRT effects, gamepads, two players on one
computer.
- The PC and Amiga versions' looks and sounds, and optionally the Atari Jaguar's
sprites and SWOS 2020's pitches.
- A real Amiga version for the A1200/A4000 (AGA), built from the same source code.
- An arcade (coin-op) mode for cabinets.

Found a bug?
Please report it: github.com/benbaker76/OpenSWOS/issues. Every report
helps, however small. Say which version you have (the bottom line of the main menu), what
you did and what happened, and attach your SWOS.log (where it is:
INSTALL.md). A screenshot or your save helps too.
