With all due respect to the impressive and long-time defacto standard, Metedit, a new Metroid (NES) editor is well under development and will probably be released some time in September.
This new editor, titled “Editroid”, supports editing screens, as well as editing the structures that screens are made out of, and the combos that structures are made out of. Editroid supports palette editing as well (including secondary palettes for the levels that have them). The text at the title screen can be edited for a custom by-line. There is also a feature to preview the “physics” of a screen. Editroid also supports some features to simplify creating a world, including the option to append map data to the ROM file, view a map of the world, a section of the world, or a specific level, and even create back-ups.
For die-hard hackers, there is a pointer conversion utility and the “Pointer Explorer,” which allows you to find the offsets of game data. And for DotNet developers Editroid doubles as a DotNet library that can be used to dissect the ROM.
Unfortunately, Editroid does not support item editing and has some compatability issues with Metedit that can be worked around.
