Nice, that you like GOW. However, if you want to finish this game on a flash cart, it will probably be quite a challenge. Without any of the emulator special functions, some bosses can be quite difficult, but it of course can be done, just needs some more blue potions.
Regarding the non release method. I think this is even a more radical concept, but I guess it works. It is logical, that the author has the version, which also works on real hardware. It is just a matter of what to make public.
Right. I've been bouncing an idea around in my head. I can set an amount of money to receive before publicly releasing my rom. That way I'll at least get something to compensate for the time and effort. If I don't get a donation of what I feel is fair that's fine, I'll just keep my work from being released. I think romhackers should do a system like this.
I just realized something with GOW. When I pick up the sword and save and then load from the save I get a black screen and can't do anything. Am I supposed to refrain from saving until a later time? I'll send you a pm about this since it's sort of off topic.
