Uh... "intel version", yeah... somehow I believed that 1.6pre was PPC when it is in fact universal
Must be because it was updated ages ago.
But thanks, both of you! I think the culprit was in fact the Dynarec CPU core. After turning it off, the games launched just fine! I could select the toast images with the "Run ISO" option. The Moby CD plugin worked fine, too. Maybe the 1001 bios helped, too. I had 1000 and 5000 earlier, it probably used 1000 since that's the first one in the list.
I think the labels on the analog L-stick settings are reversed though: up should be down, and left should be right. I'm using a Dualshock 3 controller connected with a USB cable to the Mac.
Is there any change log for PCSX reloaded? What's new since 1.6pre? And is is possible to get rid of the slight stuttering sound in the intro music in Legend of Mana and/or Chrono Cross?
