Questions
- Are these official?
- No. They're fan-made ports, decompilations and remakes, not made or endorsed by the original publishers. Fan ports sometimes get taken down, so play them while they're up.
- Do I need to download anything?
- No. Each game runs in your browser on its creator's site. A few ports ask for your own copy of the original game file, and their descriptions say so.
- Can I play them on a phone?
- Games marked Phone-friendly have touch controls. The rest need a keyboard, so they're best on a computer.
