The 1.50 kernel plugin thing is an add-on for the CFWs like, 3.80 M33 and 3.71 M33 for examples. It allows for all 1.50 kernel HBs to work under a CFW. And also allow for u to use either the normal "GAME" folder or "GAME150" folder for your 1.50 kernel HBs. Either of those folders will be the folder to put your 1.50 kernel HBs in. Depending on how you configurate it in the recovery mod configurations, that will be the folder for the 1.50 kernel HBs. So basically, it is like having duel FWs in one.
