+# The Battle for the Solar System : The Pandoran War
+
+This is the port of the "The Battle for the Solar System : The Pandoran War" 
+v1.50.1 for the AmigaOS 4. 
+
+The Pandoran War is a 2D mission-based space shooter based on the BATTLE FOR 
+THE SOLAR SYSTEM space opera and set between books two and three: THE THIRD 
+SIDE and THE ATTTRIBUTE OF THE STRONG. The game features many missions, 
+with many different objectives and craft.
+
+It requires a fast system to play the game as fast as possible, and a 
+graphics card that supports either opengl/opengles2 with SDL2.
+It is tested and runs well on X5000/40 with a RadeonRX 550. 
+
+This archive does not contain any data files. In order to play the game, you 
+need to download the data  separately. From the following website download
+the "tbftss-1.5.1.linux-x86_64.tar.gz" file.
+
+https://www.battleforthesolarsystem.com/games/pw/#downloads
+
+To install it, extract the data file anywhere at you hard disk
+and copy over all the files from this archive. A requester will show up
+to replace some files, which you need to confirm for all of them.
+
+If you like the game and would like to support its developer, you can go and
+buy it at:
+https://parallelrealities.itch.io/tbftss-the-pandoran-war
+
+### How to make it faster
+
+The game should run in 60fps but on my test system I get around 30fps with all 
+the effects enabled. That's why I introduced an option at the Options screen, 
+named "Effects Reduction" with values from 0 to 3. With 0 you have full effects
+everywhere, and with 3 you have less effects shown. That increases a lot the 
+speed, but you might still see slowdowns in situations where there is a lot of 
+action on the screen.
+
+It is recommended to open the SDL2 prefs and set the Driver to opengl/opengl2 
+depending your gfx card and the drivers you have installed.
+
+On my system "Batching Mode: enabled" leads to some crashes. I recommend you 
+to  set this to default. But feel free to experiment with it, in case it
+works better for you.
+
+I'd love to hear how it works on your system.
