  1.                UNIVERSAL QUESTIONS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

................................
            General
................................

Q: Where do I download games / ROMs?
A: Due to the questionable legality of ROM images of commercial games (see
   [http://en.wikipedia.org/wiki/Rom_images#Legal_status_of_ROMs]), the ZSNES
   Team *cannot* and *will not* provide you with any games / ROMs. We must do
   this in order to keep ZSNES, as an emulator, legal. Please see the disclaimer
   [Readme.txt].

Q: What is the "save directory"?
A: Please read more about the types of files ZSNES generates and where they are
   created in the Files section of [Readme.txt].

   By default, in the Win and DOS ports of ZSNES, these files will go into their
   corresponding ROM directory (e.g. If your Chrono Trigger ROM is in
   "C:\SNES Games\RPG", its files will go into that folder; if your Harvest Moon
   ROM is in "C:\SNES Games\Simulation", its files will go into that folder).
   In the SDL port of ZSNES, however, saves will go into "~/.zsnes" by default.
   ZSNES SDL under Mac OS X will place them in
   "~/Library/Application Support/ZSNES" instead.

   If you dislike the default settings, you can configure a single, universal
   save path by either going to the Config->Paths menu in the GUI or by editing
   the ZSNES configuration file [Advanced.txt].

Q: Why are my games not saving?
A: If your ROM images are stored on a CD-ROM, you need to define a save
   directory that points to your hard drive. In order to do this, either go to
   Config-->Paths and enter a directory, or edit the ZSNES configuration file by
   typing in a directory after "SaveDirectory=". Make sure that this directory
   is not marked read-only.

   If this still does not solve your problem, enable SRAM Check + Save under the
   Config-->Saves menu.

Q: Are the ZSNES data files compatible among the various ZSNES ports
   (Win/DOS/SDL)?
A: Yes. Unlike certain PC applications and games, ZSNES's various save files
   and formats are completely port-independent; you can share any of your files
   with any user using any port of ZSNES (although some things may be
   version-dependent). Note, however, that ZSNES's configuration file
   [Advanced.txt] contains port-specific options which don't exist in other
   ports, so while they can be transfered between ports, some things won't work
   as expected. Note that when transfering various files, make sure they're
   named properly and in the proper location (see the Files section [Readme.txt]
   for details).

Q: Is there Toaster Support?
A: While we'd love for ZSNES to lace our shoes, feed us, breathe for us, and
   amass wealth for us, we can't add every crazy feature that comes up.
   Even though ZSNES does have many, many features that are not necessarily
   SNES related, they normally don't go beyond features that you'd expect from
   an advanced gaming system.

   Regarding toaster support itself, rumor has it ZSNES does bread toasting
   if you happen to be using it after midnight while paying your respects
   to the master of all controls and considering monetary options.

             Games
................................

Q: Why don't my games work after applying IPS patches to them?
A: If your patched game crashes early or just displays a black screen, you
   probably need to either add or remove the 512 byte offset from the patch.
   Use the program IPSEDIT to do this, which is bundled along with NSRT.

   Alternatively, you could either add or remove a header from your ROM before
   patching. Again, NSRT is capable of doing this. [http://nsrt.edgeemu.com]

Q: Does ZSNES support Snes9x, GoodSNES, and NSRT ROMs? Or only ZSNES ones?
A: ZSNES, Snes9x, GoodSNES, and NSRT ROMs do not exist. All these programs work
   with SNES ROMs. As ZSNES is an SNES emulator, it will work with all SNES ROMs
   (except where ZSNES has a bug or the ROM is in an unsupported interleave
   format).

................................
             Video
................................

Q: Why do my scanlines look awful?
A: Scanlines can be negatively affected by the method of vertical scaling that
   your video card uses, depending on the video mode you have selected for
   ZSNES. This can sometimes result in scanlines that are not of uniform
   darkness. The effect of this video scaling is most noticeable with Full
   scanlines, with 50% and 25% scanlines being less noticeable. To display the
   scanlines effect properly, you should use resolutions based on a multiple of
   256x224 in windowed modes (e.g. 512x448) and 320x240 for fullscreen modes
   (e.g. 640x480).

Q: Why am I missing some video filter options?
A: Please make sure you have MMX Support enabled in the Options dialog. Refer to
   the Video Config description in [GUI.txt] to see what video options require
