CED Online
I've taken down the site but I'll leave this page up as I know there are still people out there playing No Mercy via emulation
Code Converter
The only application available at the moment is the AR Code Converter for WWF
No Mercy. It ports codes for the glitched version of the game to those for the
unglitched version. Click below to download the file
Alternatively, if you have a file named MSVBVM60.DLL in your Windows\System directory, then you can download the version below.
If after downloading this one, it does not work, you'll have to come back and download the larger file at the top of the screen.
