This patch was originally created for pixelpuck.com ROMS. First released with my NHL11 ROM, with the help of kaneda of spritesmind.net, it allows for the use of goalie control by pressing the (Y) button. Controls must be configured to six buttons for both players. Plans for the use of the (X) and (Z) buttons for line changes and a pseudo fake shot button were scrapped when I stopped doing updates.
This patch also works on real Genesis hardware if you have an Mega Everdrive or some other flash cart.
We did get it going with multi tap, 4-way play, but 4-way play has been tested on actual Genesis hardware.
Note: you can still control the goalie by depressing (B) for a second with this patch applied.
