New page

Unfortunately, links to bots' jar files became rotten. Sometimes the hosting website goes down, sometimes API is changed. Luckily we have [http://robocode-archive.strangeautomata.com archive]. To fix a link to a workable one, just replace the bad link to the archived one. You can do it by hand for your favorite bot or you can run the script below

# Check rumble page for bots with rotten links.
# If possible replace the bad link with the one pointing to archive
