How To Play?
If you want to play these games, you will need two things first:
The original Super Mario World Rom, Version 1.0 & SNEStool, which can
be found on dozens of emulation web sites around the web.
Just use a search engine to find one you like.
Also remember that ZSNES and snes9x have internal support for auto-patching IPS files
to ROMs. All you have to do is place the ROM and the IPS file in the same directory
and give them the same file name (ie. smw.smc and smw.ips). The ROM will be patched
in memory when you play the game, leaving the original ROM file intact.
