Personal NWC

I was going to ask if it is possible to have a gold/grey NWC repro cart made to look real outside (but I don't care how different the board is inside or if there is writing saying repro etc) for a web sitcom thing were working on for my website but this led me to another idea altogether that I am curious about.

Could the 3 games in the NWC be edited like other roms... like could I replace sprites in Mario, change the scenery in Rad Racer etc. or even replace the games with others?

I am totally New(b) to this type of stuff and that is why I ask. I know for the PRGE the main screen was edited, but I'm more curious about the games inside being edited.

    Its possible, you would just have to really have a good grasp of the 6502 language. The game selection would also be limited because they would all have to use the same mapper.

    It's possible, but good luck finding anyone willing to do this for you. You're treading on some very touchy territories here, regardless of your intentions.

    Doing graphics hacks of the existing games is very easy. Almost none of the code from the originals was changed, and all the graphics are just there unchanged.



    Replacing games will take much more work, and depending on the games picked would be a complete redesign.

    So you're saying I could change the graphics in each individual game, as well as the title screen - easy enough - but to replace the games would be something totally different? If I can do graphical hacks for each game and change the individual title screens as well as the main one (the actual NWC 1990 one) then that's perfect.

    You'd probably need to change 2 types of data, the graphics for the intro screen, and the nametables in between games. You might be able to also do the nametables for the opening screen, just hope it's not compressed or dynamically written to the screen and it should be pretty simple. You shouldn't need knowledge of 6502 at all, just data and what to look for, unless it's compressed or dynamic.



    Just look for the nametables data in ROM, the graphics are just there in YY-Chr when you open it (look around, you'll spot them eventually) and then look for the nametable data in the ROM via hex editor. I'd find the locations, write them down, save a copy before you start, and then just go at it until you get it changed to your hearts content.

    I could do this shit if you paid me well enough. Necrobump because I find the idea funny.
