Hey all,

I accidentally made a super-weird discovery in DSLua!

If you have an image (I use PNGs) with 256 colors USED or less, convert it to a GIF (it should convert perfectly) then convert the GIF to a 256 color BMP. The GIF colormap will override the BMP colormap. The result? An exact duplicate of your original .PNG!

I think it probably just edits the palette, replacing the unused colours with the ones used in the PNG.

I use mtPaint now ( http://mtpaint.sourceforge.net/ ) which is good because it has the 256-colour palette on the left at all times which you can pick colours from, and you can edit the palette too. Whereas MSpaint only uses a certain palette with only a few shades of each colour.

Hey dalton, what editor are you saving the png as gif and not losing quality? I use MSPaint (too poor to get photoshop) and it didn't work too well.
Tried mtpaint, but it couldn't save as gif...

...I just used paint. The original PNG has to have less than 257 colors.

I took a screen shot from the Final Fantasy 5 knight version of the main character. By looks of things, there isn't more than 256 colors used. I saved as PNG then as GIF using Paint. Here's the result:


What might I be doing wrong?

Hmm... are you using XP or 2000 or other? I use XP. Try a direct conversion, PNG --> 256 BMP.

XP Pro...

From PNG to 256 BMP is okay, just seems lighter and the colors adjusted slightly (I'm guessing to fit palette). 24bit BMP to 256 BMP acted the same.

Ah well, it's no biggie, the 256 colors will get the job done.
