so for a while now I have been pokin around in the data for the 1989 NES game River City Ransom (a.k.a. Street Gangs, a.k.a. Downtown: Hot-Blooded Story)
I'd like to get saltworlders involved in making an elaborate ROM hack, going well beyond the usual "text & tiles" type hack, to make something more like a different game on the same engine...
I made this colorful map of what I understand of the ROM data so far: http://saltquix.gith...o/barf/map.html still workin on it
here's a rough plan... subject to interest from you guys of course
I continue to investigate where things are in the ROM and also the data format involved, & add to the page above
at this stage any truly intrepid wonks are welcome to crack open a hex editor to manually try to make use of this knowledge... but this isn't recommended....
I develop some simple command-line tools which can pull out certain bits of info in a readable text-based format, then push back once you've modified it in your favourite text editor
so if you're interested in getting involved at that stage you'll need to be happy to work with doing stuff with a command line and version control (github). i'm happy to help as much as I can though.
next I'd start work on visual editors (like the actual geometry of a location, where raised surfaces and walls and pits and exit zones go)
finally, i'll attempt to consolidate all the separate little tools into a nicely wrapped-up single GUI app
I don't wanna dictate a theme for the hack...I'd rather let things emerge and percolate as they will, driven by experimentation
i think this could be cool. thoughts, comments, suggestions welcome....
(here's a useless bit of tech triv for ya: the background graphics for locations that are 3 or 4 screens wide are stored completely different to backgrounds for locations only 1 or 2 screens wide... the data is in a different format, even physically they are stored on a separate memory chip within the cartridge... #wow #whoa )
