Hey guys!
I'm reviving this old thread to post my updated situation. I recently upgraded to OS X 10.8.5 on a 21inch iMac (2013 model) 2.9GHz i5 with 8 GB ram. Huge difference over my G4 PowerPC. Tried to get GUIntv 2.1/jzintv 1.0 beta up and running with some success. Got all my roms in place and preferences set (system/game folders, Exec.bin, Grom.bin, SDL 1.2 framework, etc.)
Some games load up fine at 640x480/full screen ok, but the right and bottom parts of the screen get cropped:
Also, when I use windowed mode instead of full screen, the "shall we play a game?" file selection window gets stuck floating in front of the game window. It can't be closed or interacted with at all. The only way I've found to clear it is by force-quitting jzintv:
Last thing is some games fail to load (Atlantis, for one) and warn of a missing config file, which I see in the bin2rom config files folder of GUIntv. I did get Atlantis to work once, but it was hours ago, and all the tinkering I've done since have rendered it unload-able.
Anybody have any ideas? Any word on any software updates?
