For example, before this fix, if you enabled the "Mario flies without wingcap" cheat during gameplay, it would work, but if you then disabled it during gameplay, Mario would still be able to fly. Now it correctly restores the old memory values so Mario can't fly anymore after you disable the cheat. Note, because cheats are basically writing to a random area of memory, this function may not always restore the previous state depending on the way that area of memory is used by the game.
-Removed Cheat menu and replaced it with "Cheats..." menu item in the Options menu.
-Modified alert_message and confirm_message so they handle line wrap of the message internally, so now it's no longer necessary to insert newline chars into strings passed to alert_message and confirm_message.
-added list_find_node utility function to util.c.
-added utility functions to create/delete cheat structures for use by the gui.
-Added 'g' shortcut key that will act as the Gameshark button.
-Added user ability to map a joystick button to the Gameshark button.
Note, I did not add support for the Gameshark button to the emulator core yet, so cheats triggered by the GS button will not work until that's done.
-Changed name of cheat config file to cheats.cfg. File is now read in on startup and written out on exit.
-Changed cheat config file format to the following:
{Some Game's CRC}
name=Some Game
[Cheat Name 1]
enabled=1
XXXXXXXX YYYY <-- cheat code (address, new value)
XXXXXXXX YYYY
XXXXXXXX YYYY
[Cheat Name 2]
enabled=0
XXXXXXXX YYYY
XXXXXXXX YYYY
XXXXXXXX YYYY
{Another Game's CRC}
name=Another Game
...
Here's the cheats.cfg I used for testing:
{635a2bff 8b022326}
name=SUPER MARIO 64
[Super Mega Jumps]
enabled=1
8133b176 0008
[Jesus Mode Mario]
enabled=1
