Many people couldn't come to grips with the SAGE release of the ProSonic engine only being available for Mac. I did this because the engine wasn't where I wanted it to be for it's second release, so instead of missing SAGE and thus missing a great promotional opportunity, I prepared the engine for SAGE and limited the number of people who could play it. This would allow it to get the attention I wanted for it, and it allowed it to be tested by people who were interested.
The downside is although there were plenty of downloads, I got feedback from maybe only one or two people. That isn't helpful at all. Perhaps that's my mistake for misjudging what I thought would happen. Still, I have no regrets about holding back on a Windows release.
A new release will definitely happen in September. I have not decided on an exact day yet, but you'll hear about it from me as soon as I make a decision. The September release will include a couple extra features not available in the SAGE release. It will be released for Windows, Mac OS X, Linux, and MS-DOS. Some of the goals I originally set in my 7-point plan will not be accomplished by September. The reason for this is because I have reviewed some of my original plans, and quite frankly, some of them aren't absolutely essential in my opinion. They'll be done sometime, but they're not a "must-have."
Some things you can expect is further scripting support, slightly improved GPI support, VGZ compatibility (the SAGE release only supported standard VGM), and several editing utilities that can be used to modify data and customize the engine.
Object scripting is still in early stages of development, so there will only be certain aspects of it supported. I also plan on changing the way the backgrounds are rendered, but only after the September release (I don't want to get myself into a jam and create problems I can't fix in time.)
That's all there is to say about my engine for the moment. Keep coming back for future updates.
