WP64 has a female voice at some points which is not available in WP XL.
They probably re-recorded "Contender Eliminated" because the man was too hard to hear.
Super weapon is also heard in WP64 but not xl. 64 also has "Congratulations! 1st place!"

If you are wondering how to get 'that' menu noise with the select and BAM!, play menusel.wav then weapnhit.wav.

XL and 2097 are technically the same game but something is changed (e.g floatiness - am i right in saying that?)

EDIT: How many posts till I become Rapier Pilot?
