Hatari uses 2 different cpu core modes : - the old one is best used for STF/STE emulation - the new one will give better Falcon compatibility The archive hatari_1.8.0-2_OSX_x86.zip contains 2 versions of Hatari compiled for Intel x86 (32 and 64 bits), one for each core. It should work with OSX 10.5 to 10.9. - for better STF/STE emulation, use Hatari.app - for Falcon emulation, use Hatari_Falcon.app These versions also use the capslibrary v5.1 by SPS, allowing to access IPF and CTR files made with the Kryoflux board. Thanks to Troed Sangberg for providing these builds.
