After quite a few hours of frustration, I think I'm done now. Frustration was mainly due to the fact that no utility in existence other than pic2snes could actually do the job correctly, and even then only from GIF source. There was absolutely no utility that could convert a 16 or 256 color bitmap to SNES 4bpp format correctly without pixels missing with this particular image. Buggy software I guess.
Here is pic2snes. It was written in 1993. It works with GIF images with the GF87a option. I used xnview to convert to his particular older GIF format.
http://www.romhacking.net/utils/127/Even pic2snes was unable to convert the bitmap image correctly, but it was able to do the gif correctly. Not to mention, it outputs SNES format palette for the image and optimized tile data. Not too bad for a utility from 1993. We have nothing made since then that can do this to my knowledge. I almost set out to code something that could do this, but thankfully, I made it work with GIF.
Anyway, enough rambling. Here's the image as currently presented in the game!
Only thing left would be the Japanese copyright information, but quite frankly, they are using 26 sprites in OAM memory for this, and I'm not really too interested in hacking all of that. A lot of work for very little gain.
P.S. Thanks to DaMarsMan for pointing me in the direction of xnview and pic2snes. :beer:
