previous wine version 1.3.x uses much less resources
I doubt that. 1.3.x directly culminated into 1.4 as it was its dev version and telling from the changelog it looks at least that they dropped some useless stuff like openal, esd, jack and so on. Do you have any real proof for "much less resources" or is it just flaming?
moreover it can use oss as opposed to version 1.4
wine 1.4 can use OSSv4 but since we don't have this in the repo (AFAIR), of course no support in Tiny Core. I'm not sure there are any reasons why we shouldn't provide OSSv4, maybe someone just would have to take care about it and then wine can be rebuild with OSS support.
if possible bring back this version with changed name
As I said... it was only a development version. Where should we put the marker for what "basic" change in the development process someone likes and the other one doesn't? We should go for stable releases, so either 1.2 or 1.4, or both.
only please do not do so that when it starts
then running winecfg
what do you mean exactly? I didn't do anything special to winecfg except for the wbar icon. There is no automatic start triggered by the extension.
