If anyone is using Windows98se, don't fear El Matador works just fine on it. Using a Pentium III, 600MHZ, onboard sound, BFG 6200 OC 256MB PCI card, 90watts, 80GB HD, 2 External HD's. Using Nvidia driver 81.89.
Alright, when you start up the game, it will say a error as shown up, the error is a DLL file, called:
dinput.dll. So here is what you do to get around that error, back up the file , then deleted it from the dir. Windows98SE users does not support that DLL file, so just deleted and its not needed for the game to work.
Now, also before you start the game, a second message will appear, something about null render system target is not supported, just ignore it and enjoy playing!
I play the game at almost max out, with shadows off, AAX2 on, and get around 15-25fps, which is playable.
