PCC2 Web is a HTML5 application. It uses normal HTML/CSS to render most things (including most of the starchart!). It requires JavaScript enabled. It requires a browser with <canvas> support to draw minefields, and uses WebGL to render FLAK combat.
In short, PCC2 Web requires a browser from around 2015 or newer with JavaScript enabled. Older browsers may work, but I can no longer test for those. In particular, IE6 will probably look wrong.
Similar requirements apply to the remainder of PlanetsCentral. Some functions are only available with JavaScript enabled, for example keyboard control or some shortcuts. However, all features of the site should also be accessible without it, and the site should be usable with a text-only browser.
Known Problems
Some browsers (at least older versions of links, lynx) do not correctly handle our redirects ("post redirect get" pattern). Choose "no" when they ask you to submit a form for the third time.
Pre-"6.x" browsers (e.g. IE5, Netscape 4.01) are not supported. These browsers either lack required features, or claim to support them but fail when asked to actually do them.
