All four binaries work (MacOS is more out-of-date because of their proprietary crap, powerpc-linux will lag a bit because of my lack of accessability). Here's what you can do now:
What is the current status of AcidRain? It is currently very pre-alpha. Right now I'm just testing that things actually work on all the target architectures and I'm working on the design and proofs of concept for that design - this is all acidrain is good for so far.
How do I contact you? You can feel free to send me questions and queries by e-mail, though I reserve the right not to respond - I'm a busy guy.
When will it be done? Short answer: when it's done. Long answer: I plan to release it in stages, the first being matrix only, the second will add the "real" world, and the third will add the astral and magic. I hope to have the matrix version playable by January of 2003 and released in a stable version by May of 2003 - but these are only goals, not fixed deadlines. I will not force it out until it is really done.
Will you be releasing the source? I hope so eventually, but not at first. Unfortunately, there are a lot of imature morons out there that would just love to cheat, and realeasing binary-only releases would make that harder for them. If I find a good solution to this problem where I can still release the source code, I will (suggestions welcome).
Will you be posting binaries for other Linux architecures? Yes. As soon as it gets out of the pre-alpha phase, I will enable more linux targets and make those binaries available. This should include at least powerpc and mipsel (including Playstation 2) Liux architectures.
Will you be making a MacOS 9/X version? Yes, all the code is C99 compliant and is designed to be portable to any system that supports SDL and OpenGL for exactly this purpose.
Will you ever be posting MacOS 9/X binaries?: Only the stable version(s) will have a binary posted. This is due to the proprietary and closed nature of MacOS itself. As far as I know, I can not cross compile for it directly with gcc like I can for all the other targets, so it is more of an undertaking. If this were to change, I would put binaries up regularly like I do for windows/linux.
