(Since this seems relatively geared towards newcomers)
I'd like to add that romhacking is a very time consuming activity per se. Where model painting can take anywhere from 5 to 60 hours per model, romhacking starts at a few hours if you have the Devil's luck, and goes to actual, real, physical years for things like RPG translations and such.
This means 2 things.
When you're asking for help for someone to do something for you, you're actually asking for a lot of time, not for someone to take a ride to the nearest shop and bring nachos back.
It also (and more importantly) means that you, yourself, have to consider that you will need time to invest, and need to accept that you need to give yourself time to learn and progress. Because of that, just like for a marathon, you need to realize and be happy with every small step you take, even if it's just a step out of the whole run. You will read a lot from people that you have to break a complex task into small pieces, a complex question into smaller ones you can answer. This is linked to that.
When you look at the numbers, you'd think they're against this art. A small 50-lines C program can generate hundreds of ASM instructions, and what we get is the latter. I personally find it amazingly interesting that we can translate games at all with this. And yet we can. Take this as a mystery, a puzzle to explore, and carve your path forth.
