I did the first few of these cheats myself, then realised there's more than likely a clone / original hardware in the list somewhere. Lo and behold, there is. These are copied directly from another cheat file.
I haven't tested all of these, and the region cheat may not be needed (you can select it in the beginning). The few that I did test worked fine (health for both players, time, credit).
