The codes sections mentions these things and I had no idea they exist. ("complete 'the moon' to unlock..." etc) How am I supposed to beat them if I can't even play them?!
What are The Moon and Dristone Driller and how do I unlock them?
also to anyone who reads this: Please reply even if you can't help with my question.
and THANK YOU
oh it just occurred to me
These are all marked in the cheats section as being exclusive to the European/Japanese versions of the game
I get it now, it becomes pretty obvious now that they have content the USA version does not have.
copied from the cheats sections:
Endless Dristone Driller Level (JP/EU Versions)
Beat Dristone Driller once to unlock Tokyo being an infinitely deep level.
How to Unlock endless modes (EU/JP Versions)
Unlockable How to Unlock
Outer Space Complete "The Moon" in mission mode
South Pole Complete all earth levels in mission mode
Unlock Usagi (JPN/EU versions)
To unlock Usagi you need to complete the 2000m moon level in mission mode using Ataru.
Please note this only works in the Japanese and European versions.
I noted the possibility that these are just the same modes/levels the USA version has but with different names. But Usagi is extremely strong evidence to the contrary. (as I think I would have noticed unlocking a SEVENTH CHARACTER !!)
