A very random question yes but I really want to know the answer. I do understand that this sub is for the modernized fan based version of the game but I wanted to first play the old school version for nostalgia's sake and also because my wifi would take forever to download the entire renegade x file. Everything in the game works fine (except a lot of the cut scenes, but fine with me) up until i finish the 5th level of the game where when I finish it, it shows me my stats on the level and then goes back to the main screen even though there are up to 12 levels in total. I checked in the files and it shows all the levels as they are but they just don't show in the actual game. Anyone dealt with the same problem or might have some answer to this?
