Mike, just curious, did it take short time for you to write?
I spent half a night trying to get mine to work, all to naught due to some typo or whatever. Got dead tired in the end, went off in frustration to watch Angel Beats (good shit, btw, check on it, guys).

Open both BAMs with DLTCEP and edit the palettes. Are they exactly the same, same order and everything? Could be when you inserted your frames to the BAM (using BAM Workshop or however you did it) it reoptimised the palette.

They aren't the same. Now I need this function to get this 'optimised' palette from the source file!

If you are going to modify the palette then what is the purpose of patching the file instead of overwriting it? If each mod would modify the palette then frames added by all other mods would be corrupted.

That could get nasty, because different mods could overwrite the palette several times, probably hosing the frames that other mods have added, and possibly vanilla mapicon frames as well. [Edit: what Kwiat_W said]

It would be better if this function allowed insertion of frames as bitmaps. There is code in BAM Batcher that does this (builds BAMs from BMPs). Then you could export a frame from the vanilla mapicons.bam, edit it without changing the palette to make your new frame *or* export the palette from Paint Shop or Photoshop, then apply the palette to your existing frames with "nearest colour" matching. Should look more or less the same. But then you know you're going to have exactly the same palette. The problem with importing frames from BAM Batcher is that I think it reorganises the palette every time you do that. You might be able to avoid that with DLTCEP instead - not sure.

You're right, if anyone would do it, it isn't any better than overwriting.

Interesting, but as it turned out, it's not my case! Mike's functions works as it should be. The bug with palette turned out to be my mistake (I deleted the original mapicons.bam from override before trying the function, and thus the function got the one from the biff, with the palette slightly different). Well, curse me for a foo!l

Let's just say that it didn't work flawlessly on my first attempt, and I had to rewrite my offset adjustment / byte-adding code.


Regarding palettes, I'd prefer not having to support conversions, but I may look into it. There are only a couple different palettes being used now:

• The vanilla ToB worldmap uses the one in 25mapic.bam.
• If ToB is not installed, the SoA worldmap uses the one in the biffed mapicons.bam.
• If ToB is installed, the SoA worldmap uses the one in mapicons.bam from the override. This palette is also used by Tutu, BGT, and the Worldmap mod (where it can replace the ToB worldmap as well), so it is definitely the most common.

BAM Workshop I (available here) can easily import a sequence from another .bam (and it will automatically format the sequence to use the palette of the current file).

Edit: it turns out BAM Workshop doesn't perform miracles. The imported sequences look perfect when imported, but once you save the file and reload, they get really ugly.

Okay, the function now automatically converts the new icons to use whatever palette the existing map icon file has, so you don't have to worry about them at all.

Eh... how does it do that exactly?

For each palette entry in the icon file you provide, the nearest matching entry in the existing file is calculated (Euclidean distance). Then, the frame data that's being added is altered, with each index into the old palette being replaced with the index of the nearest match.
