Razor freestyle scooter rips

[SoulStorm64]

Hello Forum, I am trying to use a map from Razor FreeStyle Scooter for a Tony Hawks Underground Pro level mod  and  have been having a hard time with getting it to load properly in the 1964 model ripper. it seems it does not want to cooperate with the rom. 

They Also have another version for the DreamCast but i am not too familiar with Ripping Models from Dreamcast games if anybody knows how and could help that would be great.
