It's not luck. It's skill and practice.

Here's a mantra of mine that's been paraphrased numerous times for the sake of newbies like you: With a metric buttload of time, effort and cursing, anything is possible. If you know what you're doing, it takes a lot less.

You've chosen a GBA project, which is both good and bad.

The Good: Most game systems - notably the NES, SNES and Game Boy - can't access the entire ROM at once. Instead, they cheat by using "bank swapping", whereby the ROM data is split into numbered chunks that can be accessed one-at-a-time. This is murder for translation efforts because in many cases a game expects its script data (among other things) to be in one specific chunk, forcing would-be translators to either 1. butcher their translated script to fit or 2. hack the living daylights out of the game so they can split their script across multiple banks. This is not the case with the GBA, which can access the entirety of the ROM image in one gulp.

The Bad: On the upside, the NES, SNES and Game Boy have all been exhaustively documented, and there are literally mountains of tools and utilities for these favored platforms. The GBA, on the other hand, is not even a decade old, making issues of emulation and translation hacking a bit fuzzier: while it's hardly uncharted territory, information and utilities meant specifically for GBA titles are a little harder to come by. The only major compiler for GBA ASM code, Goldroad, is a piece of garbage, and the best emulator with debugging functionality is no$gba, which costs $15 (but can also emulate DS games).

I would direct you to the links on the left, but it seems you've already gone there: a good start for a newbie.

I took a look at that game awhile back and iirc it used SJIS and normal gba pointers so it shouldn't be 'that' hard except for if you want to make it polished and professional looking as iirc it used a 16x16 font and didn't allow for much text in the menues.

An acronym for "if I recall".

Ironically, you've just about got it nailed there. Getting the script done is probably the easiest part of the project. XD

All you need is someone who speaks English and Japanese and you're good to go. Mind you, it's a bonus if the person in question is actually good at both languages, and happens to be a decent writer to boot. (That last part's important. You'll never hear people claim that a great work of literature is "accurate".)

You'll probably need to delve a bit into ASM hacking to produce a professional-looking result. The game's print routine is an obvious potential offender: most Japanese games are set up to print big block characters of the 16x16 variety, which works nicely when you're printing kana and kanji, but not so well when you're printing lengthy English words written with the Roman alphabet. You can usually fix this on-the-cheap, changing it to a fixed-width 8x16 font with a handful of spotwelds. Or you can do things the extra-fancy way, and opt for a full-blown proportional font (or "VWF", "variable-width font", in romhacker parlance). This requires enough knowledge of ASM programming and the target hardware to write a brand-new print routine that shifts and combines character tiles to print proportional characters like the ones you're looking at on your screen right now. It's not the most difficult thing you could attempt with ASM, but it requires a decent amount of knowhow to pull off.

If you have any further questions, try asking KaioShin. He's putting the finishing touches on a fan translation of Dragon Quest Monsters: Caravan Heart as we speak. ^_^

EDIT: Though if the game uses SJIS encoding, there's a chance you won't need to do any work at all on the print routine. The first 128 characters of Shift-JIS are pretty much identical to ASCII: once you've found the text, try replacing a string with ASCII characters and see how it prints in-game.

Right now, this is a multipurpose quest. I wish to learn how to hack games, simply because I've seen much good come from those who can. I wish to learn Japanese, simply because I chose not to in the past, and I want to make up for that mistake.

I want to hack this game, with as much or as little help as necessary, because I enjoy the series. I've played the 2 US released games, so I'm familiar with the subject matter. It saddens me that, by default, the public missed out on 3 games in the series, all of which are hard to track down as imports, and near useless if you do not have a working knowledge of Japanese.

When you get right down to it, I am a gamer that wishes to give back something useful to the gaming world, and one way or another, I will learn something from this endeavor: either how to successfully hack the game, translate the script to English, or both. This is meant to be a bumpy road, any anyone willing to take up some of the slack is more than welcome to.

If any are willing to find the script for me, fine.

If any are willing to teach me how to find the script myself, better.

I wish to work on the translating the script... any help may be appreciated 

Have fun learning Japanese.
I dislike it very much at the moment. Of course that may have something to do with me having a test on it tomorrow....

Well, I'll be frank. The offer was before I knew you were only about to start learning Japanese. If you are just starting, the odds that you quit halfways are like 20:1 against you. And in that case all hacking work would be pretty much wasted. If you got some Japanese knowledge under your belt you can ask me again and I'll gladly reconsider.

If you don't mind starting slowly, there is nothing really speaking against learning the hacking part yourself too. Making a table and dumping a script with something like Romjuice aren't that difficult to get into.
