You can do this yourself. It's not difficult, just takes some time. Do you have an image editing program? Something like MS Paint works too, or you can get GIMP. Since I have Photoshop, I'll just write this assuming you have PS too. : D
1. Find the original Thanatos sprite and act, then convert the sprite to .bmps. You can do this using SPR Conview. If you don't have actOR, make sure you get that too, to be on the safe side. You can find both over at: http://ratemyserver....e=download_tool
2. Open an image editing program, drag in the first frame of the original Thanatos sprite, then copy and paste the first frame of the edited version onto that.
It's very likely that the colours won't match, so what you get instead is something that looks fairly different, like in this case. If that happens, there are two things you can do:
--Save the colour table of the edited version, and load it onto the original .bmp before you you copy and paste.
--Copy and paste the original Thanatos sprite frames into a new file.
Whatever you do, remember that the first colour in any table is the transparency colour.
To edit or create a colour table, go to Image --> Mode --> Indexed Color. A window will pop up, it'll look like this:
Select 'Exact' in the drop down menu, then in the same drop down menu, to go 'Custom'. That'll open a new window, this one with a whole lot of colour swatches.
I'll assume you want the magenta as the transparency colour, so that should be the first colour in the table as shown.
3. Repeat step two with every single frame. Make sure that the edited version of Thanatos is aligned with the original version every time you copy and paste into a new frame. Just to be clear, you need to open the first frame, then the second, the third, fourth, fifth, sixth, etc. in your program, and copy each frame of the edited version and paste it accordingly. This is to avoid having the sprite move in the act and end up looking off in-game, by the way.
4. Once you've got all that pasting and indexing done, convert the .bmps into a .spr using SPR Conview again (this time choose bmp to spr). I would leave Encode unchecked as it tends to cause odd glitches in-game.
5. If you renamed the sprite, then rename the .act of the original thanatos to whatever you named the sprite. Both should have the exact same file name.
And that should be it in terms of editing. :U Hope that helped a little. Lemme know if you have further questions.
