Contributions would NOT have to be cross-platform (in other words, there's no requirement that they run on all platforms supported by BBCSDL). For example, perhaps you have written (or wish to write) a game specifically for phones (Android and/or iOS), that's fine with me. Personally, I'm kind of planning on writing a 2D game for Linux (Ubuntu, Mint and Raspbian) desktop-based systems. If it runs under BBCSDL (Windows) as I'm sure it will, then that's a bonus. It would be too awkward to play without a keyboard on, say, a mobile phone phone.
All I would ask, respectfully, is that you write your game(s) to be frame-rate independent (if possible) so that it runs or plays at similar speeds across various systems. Not doing this is a mistake I've made too many times in the past!
Anyway, first I'd like to gauge the level of interest among BBCSDL users as I don't intend to be the only one contributing to this proposed BBCSDL Games web page!
If there's insufficient interest then I might as well knock the idea on the head.

David.
