I've got a slim silver PS2 and wanted to buy some PS1 games. I've noticed that the PS2 games that come on CDs instead of DVDs (blue disc vs. normal silver) spin loudly — it's like I left a hairdryer in my game cabinet! Just like how CDs spin up noisily in a PC or laptop DVD drive. I always found it an obnoxious design flaw.
Well, my question is: Do you know if PS1 games are like this in the PS2? If so, I'll probably spend the extra few bucks to get a PS1 to catch up on my vintage games.
