Great Game
 

Found this online password generator. Works for all levels and gives you extras too: http://fasttime.org/Dyna-Blaster-Password-Generator/
BTW great game :max:

I was playing Dyna in mid 90es and was writing down passwords. Once I re-entered the password and must have entered some letter wrong. I was on world 3 and suddenly I got tons of bombs with veeeeery long flames. Never understood how that happened. But yeah, obviously it was a way to trigger some cheats as well.
