BOTHKILL is a two-player game. Controls: Player 1 Player 2 Up: Q 0 (zero) Down: S O Fire: CapsShift Space The game was ready since 1998 but was reconditioned in June 2007: - increased playability by using interrupts (Since 1998 I wanted to learn interrupt programming and finally - in 2007 - I got to grasp the very basics of it !!!) - changed a little bit the control Keys (since the PS-2 PC Keyboard is crying out loud on certain 3-key combinations) - the assembly-language source code is available as a separate file. Since the original source code is no longer available, I couldn't recall all the relevant names for labels. Anyway, I could identify the DEFB areas and made some useful (I think) comments. I am not a programmer, so don't be too critic with the somtimes-poor programming techniques. I didn't do the sound routines - I copied them from a book. - No copyright or any of the sort related to this game. Only GOD has copyright on us all and I'm very happy to be part of the work of the PROGRAMMER of the universe! P.S. It would not be useful to use the PC-Keyboard 'Backspace' key.
