Bounty Bob Strikes Back issue............

Hello.
I have try this game on a Atari 600XL, upgraded with Ultimate 1MB and with the memory in "standard" setting. I tried about 7 different versions, 4x ATR and 3x XEX files.
In all versions game load normally, but when go into the game joystick directions doesn't work at all!!??    Only the fire button for "jump" movement work.

Have anyone else this issue?
