There are 2 games that freeze whenever I get to a certain point.
They're Trauma Center: Under The Knife and Phoenix Wright: Ace Attorney.
For the first game, near the beginning of Operation 28.
For the second game, when Ema checks the wallet.
For those of you who've never played these games, you probobly won't get what this means.

I want to know why it freezes.  Is it my emulator (iDeaS) or the games.

Freezes could be due to incorrect sound and/or save type settings. Have tried any other emulators? (No$GBA, DeSmuMe, NeonDS)

Incorrect sound?  What do you mean by that?
The save type is "Auto" and it's worked up to now. 
Come to think of it, I used the "save state" for the first game and the normal game save doesn't work anymore. 
I didn't try other emulators yet.

By incorrect sound settings, I meant that sometimes games require sound to be enabled for them to work.

The sound works fine so the only problems are the freezing, slowness and "failed attempt to save".

Well, if it's not working on iDeaS, trying another emu is probably your best bet...

Yay!  Thank you so much!  The DeSmuMe was able to run the games well.  I thought the save files weren't going to work but they did. The music sounds different but thank you! :P
