...some reported above games worked, some said not working...after struggling for quite a while I found a trick to make them worked (like a charm!)...yeah

...don't even have to change console region, all you need is a game save in your VMU and launch the game... (get a game save from a friend, or create one by playing game disc... if both not available, read below...)

note: sometimes it may seem not working, just re-start DS and try again, it will work !!

P.S. if not possible to get a game save, up/down grade the file DS_CORE.BIN (get it from github history...), by swapping this file there should be one that can trigger a successful launch of the game, remember to create a game save, then switch back to your original DS_CORE.BIN, all will be working afterwards... hurrah !!
