Ha yeah.......wow these are going back a few years
I used to love these even though they got slated all the time in reviews
I never bought JA2UB though......kinda didnt get any publicity
ok I found this site for you
it lists loads of stuff for JA2 i think a lot of the things are the same for JA2UB..(making items etc)
It has walkthrough's hints and tips for JA2UB

Hopefully that will all help
