Need For Madness: Maximum Overfly In NFM 1
You can play Maximum Overfly, a NFM 2 stage in NFM 1! To do so, delete all of the piles and walls in the text file. Not sure what they are but also delete all of the pieces that are in the numbers 60-79. Then use the find + replace edit tool to replace all the stage 43 and 44 pieces with 15. 43 and 44 are the bumpy dirt track pieces used in Need For Madness 2 and afterwards. Another step is to change 47, the first track piece to a 10.
An amazing resource is this AIM Games Track Part Topic. Go here to view codes for track pieces if you are having difficulty.

I'm not sure why I did this; Out of boredom? I really love Need For Madness 1 and converting tracks from later NFM versions to be played in it. I gotta say too the audio is nice and crispy. Kinda cursed but also nice.
