I'm working now in a hack of Earthworm Jim 3 (The NES pirate port) by Hummer Team and published by NT, the point of the hack is change the palette of the game to be more accurate to the colors of the Sega Genesis (MegaDrive) version and redraw some sprites in the game and also some tweaks.
Here's a preview:
The help that I need is how can I modify the HUD in-game to look more accurate to the original EWJ, and some inaccurate colors in a sprite, (like Jim hanging of a chain, part of his body looks blue like the suit), I made a mock-up how I want to see it:
A curious thing that I found editing the CHR is the percent sign (%) and the "X" indicating the number of lives and ammo but now unused, in the HUD fix that I want is use those signs to be more aesthetic.
I don't know too much about Hex Editing than Text edition and palette change, this a thing that I want to do in some pirate games that can look not bad but with some changes can be a good port, like Sonic 3D Blast 5 that has now a great improvement in graphics and sound, Aladdin too with more responsive controls and more accurate music to the original SNES one, by the way I don't nothing about creating and putting new music to a nes game, I've seen that was too hard but if this game (Earthworm Jim 3) can get a full improvement would be awesome.
That's the things I need to explain, I hope that we can help me, thanks!
