==  ZSNES 1.51 for Intel Mac ==
This is an *unofficial* release of ZSNES compiled for Mac OS X. It is, however, most likely the closest one is going to get to an official release of ZSNES for the Mac until at least version 1.60.

This is not an Universal binary, it runs on Intel Macs *only*. It's basically the 1.51 sources of the ZSNES SDL port compiled for Intel OS X with some bugfixes backported from SVN to fix OS X-specific bugs. Note that around 75% of the ZSNES code is written in x86 assembly, which means that will *never* be available for PowerPC Macs. If you need a SNES emulator that runs on PowerPC Macs, try bsnes or Snes9x.

Many thanks to Deathlike for listening to my bug reports over and over and for his multiple attempts to fix ZSNES's remaining OS X bugs, Hector for getting ZSNES to work in OS X in the first place and the ZSNES dev team in general for ZSNES. :)

== BUGS ==
There are still a few known unsolved OS X only bugs.
1) Using the "Interpolation" filter with the option "Scanlines: none" causes ZSNES to crash under the video mode 512x448 DR (W and F).
2) Switching from non-OpenGL (no O) to OpenGL (O) modes may cause the GUI and/or the emulated game's colors to become all glitchy and weird. If this happens, don't worry, simply save your game (savestates are ok) and restart ZSNES.
3) 8-point Interpolation sound seems to be broken, pressing ESC while a game is running locks up ZSNES sometimes. Just use Gaussian Interpolation instead (the default).

== Upgrading from the "1.43pre" version: ==
If you're currently running the "1.43pre" version available from http://hectorchu.googlepages.com/, this version (and the following ones) won't be able to find your configuration files/SRAM data/savestates unless you move them from their current location. This is because the ZSNES's SDL port used to use ~/.zsnes (~ being your home folder) to store those files in the past, but that has been changed in later versions to use the ~/Library/Application Support/ folder under OS X instead. You can move all of your saved data from the older version by opening Terminal.app (It's inside Utilities in your Applications folder) and typing the following command:
mv ~/.zsnes/ ~/Library/Application\ Support/ZSNES/

This must be done for each user that has saved data remaining from the previous ZSNES version.
