Greetings everyone, first post here. I'm a C programmer on OpenBSD who is making just a little progress in making a game for NES. I have CC65 set up, according to Shiru's tutorial, and I'm able to compile and run .nes binaries with FCEUX. My goal is first to make Towers of Hanoi, and I'd ultimately like to make my answer to the Atari game, Adventure.
All that said, I need a tool to modify CHR files, and one that will work on BSD. I have tried a couple DOS tools in Dosbox, which certainly didn't seem to work. I'm perfectly able to run a CHR through hexedit and see the really obvious patterns of image data, but I know nothing about the format. (Got further reading?) That gave me the idea of just writing a program to open any binary file, as a hex editor, and display each byte as a color in a 256-color palette. But really, a Gimp plugin might be best for my case.
I really appreciate any help, and thank you so much for this site.
