How are divisions by zero handled?
Hi,

I was playing around with raycasting on PSP and the emulator was very useful to perform the tests.

Then, I decided to dig my PSP out of its drawer and wanted to give a try after getting a result very close to Wolfenstein 3D. I was very surprised when the demo on the real hardware merely crashed at the launch.

After several headaches, I found out that the emulator kept going after a division by zero whereas the real console cringed hard. That makes me wonder: why the emulator does not crash (or at least stopped) like the real hardware after such an error?
