This is a game for ATARI ST mono emulators. It is written in GFA BASIC 3.6. It is not tested on a real machine and it is possible, that it can't be run on it. You can try to run DWOS.PRG or DWOS.GFA in a GFA BASIC interpreter. DWOS.PRG runs with the emulator hatari 1.8.0 and its built-in EmuTOS-image (https://hatari.tuxfamily.org/download.html). DWOS.PRG also runs with Steem v3.2 and the TOS-ROM tos1.02de (http://steem.atari.st). It isn't compatible to STEmulator. GFA BASIC was chosen as programming language to write a program compatible to EmuTOS. The game can also be run with hataroid and its built-in EmuTOS-image. hataroid is available for Android devices.
