Issues on versions before `in-20100207-1` about indevproxy HOT 2 CLOSED

Hi! Sorry for the delay in my response, finally got some time to handle this 😅

It's an old project so I don't quite remember the compatible versions (should have noted them in the README file in hindsight), but based on the few Indev versions that I just tested, indeed works work with yours, in-20091223-2.
Saving works but sounds/music doesn't in in-20100129 and in-20100201-1.
Saving and sounds/music works well starting from version in-20100207-1.

Please note that the save feature is only supported in versions of the game that could save locally to a file (in-20091223-2 does not have the "Save file..." button to do this). I remember that the 5 items of the level lists was never supported.
I suspect that older versions of Minecraft expect a different response format than what IndevProxy is replying with. I can't promise to provide a fix, but I might take a look at this.

After a bit of investigation, unfortunately this proxy indeed won't cut it for a version this early, sorry 😅
