TW_Notes
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Twin World v1.5 (7 November 1996) ================================= System Requirements =================== To run the game --------------- For Archimedes series machines 1MB RAM and RISC OS 2 or later. For Risc PC series machines 2MB RAM and RISC OS 3.5 or later. A joystick is recommended but not required. To view the instructions ------------------------ StrongHelp 2 or later (the latest version can be found on author Guttorm Vik's web page - see http://login.eunet.no/~guttorvi/strong.html). Acorn's 'DrawFile' module v1.30 or later (the latest version can be obtained from Acorn's FTP site - http://www.art.acorn.co.uk/ftp/riscos/releases/drawfile. arc). Installation ============ Floppy Disc ----------- Copy the !TwinWorld directory contained in this archive to a blank 800K (D) or 1.6M format disc. Note that the game will NOT fit on an E format disc. Hard Disc --------- Copy the !TwinWorld directory contained in this archive to a directory on your hard disc. Note: If you already have the old version of TwinWorld please delete both the old !TwinWorld and !TwinInfo directories. The information that was previously contained in the !TwinInfo application is now in the StrongHelp file supplied inside the new !TwinWorld directory. Instructions ============ For full game instructions, please refer to the StrongHelp file supplied with the game. To view the help, click the Menu button of the mouse over the TwinWorld icon, then select 'Help' from the 'Application' menu. Note that you must have a copy of StrongHelp 2 in order to view the help. To see the diagram in the section entitled 'The Scoreboard' you also need Acorn's DrawFile module. Both StrongHelp and the DrawFile module are widely available, and if you have Internet access may be downloaded from the addresses given above. Technical Notes =============== For users of pre-Risc PC machines the version of Twin World contained in this release is essentially the same as the original version released in 1990. Only one change has been made - TwinWorld now supports any joystick interface that provides a valid Joystick module (i.e. one implementing the Joystick_Read SWI.) The code that provided explicit support for the RTFM joystick interface in the previous version has been removed. For Risc PC users this release contains a new version of the TwinWorld program. The new version will select the best available screen mode and will run at the correct speed regardless of the monitor's refresh rate. The program has been designed to automatically pick the best settings, but if you like tinkering you can alter the game's choice of screen mode and timing method by setting some environment variables in the !Run file. See the comments in the !Run file for more details. The new version no longer does any direct hardware access, it only uses legal RISC OS calls, so it should be compatible with future versions of RISC OS. Screen modes and the Risc PC version ------------------------------------ Twin World will run in any 256 colour screen mode that is at least 320 pixels wide and 200 pixels high. If the mode is 400 pixels or more in height, every pixel line is plotted twice on the screen. This avoids the 'letterbox' effect, but it can make things look a bit blocky. The game was designed to run at 50Hz, so in modes that have a higher refresh rate the screen is not updated every frame, but every one and a bit frames. This gets the speed correct, but the scrolling will no longer be perfectly smooth. If your monitor will support modes with a 50Hz or 100Hz vertical frame rate (you can find out by looking at the 'specifications' section of the manual supplied with your monitor) you will get best results by using a 50Hz or 100Hz mode. Note that even if your monitor is capable of running at these rates, the game cannot change to a mode with this rate unless such a mode is included in your monitor definition file. You can view and edit your monitor definition file my using the MakeModes application supplied by Acorn, but I do not recommend making changes unless you are confident that you understand what you are doing. Make sure you read the MakeModes documentation and Acorn's Application Note 254 'Creating monitor definition files for the Risc PC' before you start. Both MakeModes and the Application Note can be downloaded from Acorn's FTP site - see http://www.art.acorn.co.uk for details. If you want to create a new mode for Twin World I would recommend a 320x400 mode running at 50Hz or 100Hz. This will usually give the smoothest results. --- James Byrne (jbyrne@gol.com), Tokyo, 7 November 1996.
