Great job!
By the way, I have seen the following:
--------------
Link Mode :
The front car colored texture can be replaced by the black & white one
to prevent from having a RED front car for every player in a multiplayer race (LINK).
The Model 2 will color the texture (Blue, Green, Yellow, Pink...), depending on the car you drive.
You'll have to edit the .pat file of the corresponding rom (daytona.pat, daytonas.pat, etc...) with the notepad or a text editor :
find & replace the line :
19104011 DEBDE4F2 8 Car_front.png
by
19104011 DEBDE4F2 0 Car_front_Link.png
--------
But in my daytona.pat, I can only find this:
19104011 DEBDE4F2 5 Car_front.png
Can I replace that with "19104011 DEBDE4F2 0 Car_front_Link.png"?
Actually, I haven't played this game in Link Mode, so I don't really understand what this issue is. If you don't mind, could you show it by means of a picture or a video?
