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.

Installation

To install Wii7800, simply extract the zip file directly to your SD card or USB device (retain the hierarchical structure exactly).

User guide

Lightgun Accuracy

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.

Cartridge Database

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).

Cartidge/ROM compatibility

There are many dumps of ROMs that are incompatible with Wii7800. However, there is typically a dump of the cartridge that does work.

Please see the Cartridge Compatibility List, it contains a list of compatible ROMs by hash code.

SMB/Network support

Wii7800 allows for loading ROMs over the network via SMB. To enable SMB support, you must edit the "wii7800.conf" file located in the wii7800 directory and provide values for the following:

• share_ip - IP address of the computer to connect to.
• share_name - Name of the share on the computer.
• share_user - Name of the user to connect as.
• share_pass - Password for the user.
