# Wii7800
|
|
|
|
Ported by raz0red
|
|
|
|
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.

## Current status
|
|
|
|
Wii7800 is an ongoing work in progress. For the latest project information,
|
|
please visit the [Wii7800 page](http://www.wiibrew.org/wiki/Wii7800) on WiiBrew:
|
|
|
|
[http://www.wiibrew.org/wiki/Wii7800]
|
|
|
|
## Known issues
|
|
|
|
- High Score cartridge is only compatible with NTSC games.
|
|
|
|
## Installation
|
|
|
|
To install Wii7800, simply extract the zip file directly to your SD card
|
|
or USB device (retain the hierarchical structure exactly).
|
|
|
|
## Lightgun Accuracy, etc.
|
|
|
|
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).
|
|
|
|
## Cartridge/ROM Compatibility
|
|
|
|
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".
