This looks silly but it's a whole day of coding.

MOV instruction with different modes works. Still no negative values support.

This means simple Imp warrior program is simulated properly as shown on the recording.

#CoreWar #Assembly #x86

Printing warrior code done. Last feature was showing one or two operands (they all have two in memory.)

Now I need to create arena and insert two warriors. This will finish preparing for the most fun last step: simulation!

#x86 #Assembly #CoreWar

SMOLiX CoreWar first steps.

With just 3 bytes I have:
- program id (0-1) + opcode (0-15)
- destination: mode (0-3) + sign (0-1) + value (0-15)
- source: mode (0-3) + sign (0-1) + value (0-15)

The IMP warrior is:
db 0x01, 0x41, 0x40 => MOV $1, $0

Do anyone remember CoreWar?

I was thinking of doing some scripting language for my OS and then I recalled CoreWar. I was playing with it back in the days. It's simple and fun. The full RedCode is way too complicated for my needs so I started thinking about my own version.

Here's the latest draft.

Here's a 3D MDS map of the top 100 warriors from the 88 Koenigstuhl. Each point represents a warrior. The closer a point is to another point, the closer the warrior's scores are. #corewar

Core War history - Darwin was a computer game developed on the IBM 7090 at Bell Labs in 1961, where user-written programs competed to control core memory. https://corewar.co.uk/darwin.htm #corewar

Creeper was the first computer worm, spreading across ARPANET in 1971 with the message "I’m the creeper, catch me if you can!" Here's the story of Creeper and Reaper, which inspired Core War https://corewar.co.uk/creeper.htm #corewar

Here's a multidimensional scaling map of the 94-Koenigstuhl top 100. #corewar

🥇 Stasis Prime and Mountain Viper have entered the top-50 of the 88-Koenigstuhl in first and second place. Congrats to inversed https://asdflkj.net/COREWAR/88/TOP50/hill32.html #corewar

HELP! Can you help to fill any gaps in the Core War archives? We're looking to add any missing tournament entries, warriors, articles, simulators, and anything for related programming games. Thanks 🙂 #corewar

MARS update: for macro expander has been moved to operate on the token stream between the lexer and parser for better compatibility. This update took a log of work, but the remaining compatibility features should be much simpler now that it is done.
