My ROM-hack: "Silly Fox"
I had a trial period for a hex editor, and I made use of it by editing the text in the classic SNES game "Star Fox" :)
I made this several years ago, so some of the humor's childish. Plus I was very limited by number of characters I could use in the speech, since overstepping the boundaries would mess up surrounding code and cause glitches in the game. I think I managed to pull this off glitch-free, but if you find any let me know. And no, I'm not an L33t h4x0r, so you won't see anything fancy like a changed title screen or anything; just silly, silly dialog. ^_^
Enjoy! (Should work for the more popular and powerful emulators that support the FX chip technology)
