Big thanks to CandyISO for skin-media contributions

Features:
- Emulates the Atari 2600
- Accurate Pitfall 2 emulation and SuperCharger emulation
- Near perfect compatibility - ported from Z26
- Cheat system - Search/Create your own cheat codes (see notes)
- Favorites list
- Netplay

- Skin-able
- Samba/NetBIOS sharing support (read roms from your PC)
- Relax Network Sharing (read roms from your PC)
- Play MP3 or M3U playlists in the background (Can also read MP3/M3U from across Samba/Relax shares.)
- User definable save directory. If you don't like the default of E:SAVES26X you can change it via the Z26X.INI file
- Take in-game screenshots and display them on the game selection list
- New UI feature - auto-screenshot capture mode. When enabled, the emu will start taking screenshots at a user-defined interval. Useful for ripping sprites/animation.
- Graphics filters.
- Record/Playback feature - record your gameplay in the emu and then play it back again. Record up to 10 minutes of gameplay.
- Every single in-game command is fully customizable on any of the four joypad controllers.
- Map any emulator or UI command to a single button or a combination of two buttons. (e.g. RTrigger+LTrigger = Save State)
- Autofire capabilities for any emulator button on any controller
- One-button combos (define a series of emulator commands to be played back when you press a user-definable XBox controller combination.) (E.g. Press RTrigger+LTrigger to execute the command string A,B,A,B,Up,Down,Left,Right)
- Traverse any directory on any drive ( Continue selecting the parent directory entry on the file selection list to get the drive selection list. Selectable drives are C, D, E, F, R, X, Y, Z, and SMB. R is the CDROM drive. SMB is the samba share you have defined in your Z26X.ini file.) Press Y from any file-listing screen to go up one directory level.
- All UI commands (save state, load state, screenshot, etc) can be invoked from the Options/Pause menu as well as in-game via your customized joypad mappings.
- Can be invoked from a command-line to directly run a game from a front-end or dashboard and bypass the user-selection screens. (Only if the frontend or dashboard supports this feature.)
- Can return to the launching program *if* the launching program supports this feature. For example, if the custom-launch routines are incorporated into a new frontend, that frontend could launch Z26X and when you exit Z26X, that frontend can be automatically reloaded.
