I'm starting out with (What seemed to be) a fairly simple project to make a regular gameboy game in Full Color (If you count GBC color as "Full") BUT I seem to have hit a snag. I was able to get some of the sprites the right colors for what I wanted, but when I tried to save it as a rom and open it in VBA, it just makes this wierd low pitched noise and shows a blank white screen. I tried different BG Refresh rates, but nothing changed.

GameBoy Colorizer Tool <- What I'm using.

If someone could lend me a hand that'd be great ^_^

Also, as a note, the original rom does run on VBA.

I've heard that the GameBoy Colorizer is a very unreliable program, and it only works if the game is arranged "just so" -- and it turns out that there's only like 2 or 3 games that it actually works with -- which is why you don't see very many GB games that have been colorized (only one I can think of is Metroid -- and even it had glitches).  So using that tool probably won't do the job.

Though that's all secondhand information, as I've never used it myself.

I see... Well, wish I'd known that before I wasted 2 hours, but oh well.

Don't suppose there is another program/method for coloring GB games?

There's not going to be an easy way that will work for every game out there.  It involves changing palette information -- actually ADDING information which means you'll probably need to find free space, change a bunch of pointers and whatnot.  Worst case scenario might even involve heavy rewriting of drawing routines (asm work).

Not really a project I'd recommend as a introductory to ROM hacking.  Sorry to be the bearer of bad news  :'(

Yep. It will involve finding free space and replacing the old palette routines (fairly standard, can be found easily) with your new ones. Then of course, you need to think of a system of how to load palette information and design and implement it.
Basically, it's work that sucks. Why? Because you only see a visible change to your liking after you wrote all the code and did everything right. All steps in between will look like crap or not load color at all.

It really is no project for a novice hacker. However, you can always turn out to be one of the best hackers around and show everybody how wrong they were about you Wink

Can someone Close/Delete this topic? I want to make another but don't want to have 2 on the first pag (In my experience, that's usually a bad thing)

There is usually nothing wrong with making another topic if it is a completely different discussion.

At least, I think there is nothing wrong with that.

If it is relevant to this discussion continue posting it here, if it is something entirely new make a new topic. If it is just a simple question, you can add it here if you want, most people will probably take a peek. I believe you are able to now edit thread titles, if not I can edit it for you.
