    Is there anything that would allow me to view data (and possibly change it too) from a GBA game?

    The game I want to rip is... Dragon Quest Monsters: Caravan Heart. It's a japanese game so...

    Anything like Nitro Explorer would do.

    Unlike the DS GBA commercial games do not have a filesystem. There are some tools that can rip sounds using the sappy format (kind of like SDAT on the DS but not quite as universal), scan for compression (and try to display it as graphics) and there are game specific tools (mainly for the likes of pokemon and golden sun) and lists of data for other games (see stuff like http://datacrystal.romhacking.net/wiki/Category:GBA_games ) but nothing I am aware of for this game.

    Also there was a translation http://www.romhacking.net/translations/1252/ , you could probably use it to narrow things down (text would be changed or repointed eliminating that).

    After this you are venturing into the ASM world although it is not that troublesome compared to some techniques- http://www.romhacking.net/docs/361/

    What I want from this is a way to adjust the HP of enemies. Is that possible?

    You were really asking the wrong question in the first post. "How many and where are the tools to edit GBA games?" is more appropriate. For HP editing, you need to figure out where in the cartridge the tables for the enemies are. This is of course assuming that the game's enemy data isn't compressed. The ROM hacking site is an excellent place to start looking.

    And the first reply is correct. GBA games don't use a linear file system that you can just extract blindly. You have to find out where the data you want is located and then extract the 'file' manually. Using the term 'file' is actually a bad idea and just confusing. The concept doesn't actually translate very well to a ROM image. It's not really just an archive like RAR or ZIP. The analogy of a blender and food is more reasonable. Everything is all mixed up and often out of order! :P
