So, not sure on the rules of necroposting... and it's probably late, however I did swap the soundfiles files Urbz, Sims 2 and Spyro on the DS have, and all three use the same sound engine. It worked (except for crashing where audio data was missing for each part of each game - Sims 2/Spyro data...
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
