Not sure what you mean by "full working program", there are plenty of stable versions already out there.
Worth also mentioning that (I believe), TrainSim Framework - the new name for oBVE - is starting to move away from BVE compatability and more towards new features from a new format.
I find the stable versions remark quite funny, that's the whole problem with Open Bve.
What are we up to with it now?
15 or so different ones and only the latest one available to download!
Is it better from a game or a developers point of view?
Not really, wonderful coding though.
Personally if TSF does not support Bve type work it's TSF's loss.
The current train and route content is thanks to Bve developers who have supported Open Bve for the last couple of years.
So how nice to find out you will be dumped.
I am sure a load of new developers will appear for TSF, just like they have for Open Bve!
Could all those versions be putting anyone off?
Somehow I think so.
I should point out that there's possibly more people out there that download my Bve4 trains than the Open ones worldwide.
That's why I've started to support Bve4 again.
Infact Open has never actually supported Bve type work correctly, quite a few issues have never been corrected in all the versions.
So if the rather naff support does disappear with TSF, the stable version that works best with Bve type work might be made available elsewere.
It's 'open' after all.
