How to downgrade 3.8 m33-4 back to 3.71

I was wondering if I can downgrade back to 3.71 as I want to use Irshell :(

I have original 1.5 and 1.5 kernal thing now, I updated custom 3.5 to 3.71 etc to custom 3.80 m33-4, if that changes or anything

irshell works with 3.80m33-4 read here and try again http://irshell.org/showthread.php?ti...d=8118#pid8118

thanks for the reply...I think only 1.5 version works on it though, thats why I want to downgrade

But if you have the 150 kernel add-on installed just run it from the GAME150 folder.

mmmm do all the features work on the 1.5 one though...?

As far as i am aware they do I have not heard any different.

-EDIT- After some reading around it seems some features MAY be disabled its trial and error
