programming question

[trentlogain2]

theoretically, would it be possible to program a game for the SNES? i loved the game F-Zero for the Super. The only drawback that game has was that it was not two-player. How difficult would it be too program a two player version of that game for the SNES?

How much would it cost to do this?

You would have to create a custom ROM/hack an existing one. It's pretty much all hex editing. So, difficult. You would be far better off just coding a similar game in a modern programming language (not that doing that is easy, either).

It's more than just hex editing. My guess would be it was coded in C++, but I do know that those old game systems converted that code into something else when in actual assembly. This is because PC programming languages are way too large in bit-size or way too RAM-intensive for the SNES to process it, and so PC languages are only used in PRODUCTION of the game, but not on the SNES chipset.

There are ways to convert ROMs into C++ so that you can edit them on your PC, but as for converting it back into SNES language, I have no idea. I used to mess around with it a little but it was pretty tedious. You may want to try to find the book Super NES Programming which is intended for those who wish to make their own SNES games. However note that editing a copyrighted game IS illegal.

As for wanting to make a game two player, it would involve completely reverse engineering the game engine and reconstructing it to advocate to a second controller. The game itself is only programmed to respond to one, and so the second controller would need to be integrated into the coding, a new menu option would need to be added, and those would also require new menu and character sprites to select the 2-player option.

Here's some info on how to program controllers:

Well.
I think it's not so difficult if you have some experience.
I think the best way to start programming games is with python ,I don't have experience with python , but I have some friends that already developed games with python.
For example, I saw a game recently made in python(I think is the name of the programming language) and looks like snes.
I don't know what programming language was built the snes games, but I think it's easier to program in python.
