Wii7800 is a port of the ProSystem emulator developed by Greg Stanton. Additional changes developed by Ludovic Jacomme aka Zx-81 (PSP port), Leonis, and gdement. Portions of the Pokey code were adapted from the MAME implementation.

Wii7800 0.5 + Atari 7800 Homebrew Video
Wii7800 is an ongoing work in progress. For the latest project information, please visit the Wii7800 page on WiiBrew:

- High Score cartridge is only compatible with NTSC games.
To install Wii7800, simply extract the zip file directly to your SD card or USB device (retain the hierarchical structure exactly).
The crosshair for the Wii7800 emulator is not perfect. For example, you may be pointing at something and your shot may register slightly to the right or left.
Wii7800 ships with a database that contains recommended settings for the majority of commercial and a limited number of homebrew cartridges. These settings cover control settings, difficulty switch settings, and cartridge-related settings (cartridge type, Pokey support, XM support, high score cart support, etc.).
To view/edit the settings applied for a particular cartridge perform the following steps:
- Load the cartridge (via the "Load cartridge" menu item)
- Return to the Wii7800 menu
- Select the "Cartridge-specific settings" menu item
- View/edit the settings for the cartridge
Some settings will not be applied until the settings are saved and the cartridge is reloaded. When one of these settings is modified, a message will be displayed indicating that this particular setting requires the cartridge to be reloaded (and the settings saved prior to loading).
Other settings, such as difficulty switch and control settings may not be applied until the cartridge is reset (or reloaded).
To find out if a particular cartridge/ROM is compatible with Wii7800, please refer to the following page.
[http://www.wiibrew.org/wiki/Wii7800/Cartridge_Compatbility]
Note: There are many dumps of ROMs that are incompatible with Wii7800. However, there is typically a dump of the cartridge that does work. This page contains a list of compatible ROMs by "hash code".
