Thank you guys for the good words.
Unfortunately I have not fixed the old games to work with last version because on version higher than 4153 compatability errors are going much much hard and will take much more time and efforts than I am doing now to make it work on 4107 (or 3979). May be one day will fix them for the last version... :

So for now I am fixing all old games for version lower than 4153. Use version lower than 4153 (for example 4107 or 3979). If you use higher than 4153 some games will need more fixes. :-\
The reason to fix the the old games to work on higher version is to make them playable on OpenBOR available for devices different than PC, like Android phones etc. Because originally old games require old OpenBOR version which is unavailable for many devices.
Version 4107 (or 3979) is quite recent, available for all devices, and all new recently released games work on 4107 (and 3979) as well 8)
Along with
compatibility fixes, I fix the games from
broken levels,
stuck enemies,
crashing enemies,
stuck levels etc. to guarantee the game is playable from begin to end.

Also I pass the games through my tool (can be downloaded from here
http://www.chronocrash.com/forum/index.php?action=tpmod;dl=item283) to
clean all orphan audio files that is stuffed inside and take space for nothing. So the game reduce its size.
I do not add new levels, characters, enemies, weapons or anything else. I keep the games in its original gameplay, only fix errors to make game playable
