It was time for some fun with old pixels, so I played around with the notion of injecting some graphical changes of mine into Phantasy Star 1 (1987) for the Sega Master System. My Alis is supposed to look more like the character design, but it might be a little gritty, many minor details fighting for pixel space. As usual, I'm in favor of partially coloring or omitting outlines, especially around the bases/feet to ground the masses, and at the top to suggest light... bloom? I added some color noise and hues here and there to liven things up, but I'm not sure if it just makes things dirty instead. I'm unsure about keeping the snot-green field so large on the trees. I wanted to be faithful to the originals.
I might be wrong, but the starting town might be on a platform (the EXIT could be an elevator), so some atmospheric perspective over the edge would be nice. There appears to be a palette entry for it, but it's a warm green similar to the regular grass.

This is the first time I've worked with SMS hardware restrictions, so I wrote a program to help me fiddle around with the game data. I might have messed up the endianess on the patterns/sprites, because they're flipped. Pixels can have 16 colors (from 16 color BG or FG palette) so they are 4 bit planes (8 rows of 4 bytes each for an 8*8 tile). I guess a global palette makes it more difficult to change enemy colors (e.g red/blue Octorok). In Phantasy Star you only encounter one graphical enemy at a time, and the building are all different graphically. I'm thinking the palette, or part of, is changed by the program during encounters with NPCs or enemies.
Hunting these palettes tables down is somewhat difficult as they seem to be scattered about (as are the pattern tables). A color is defined by a byte, or rather, 6 bits, like 00bbggrr, meaning, only a 2 bit resolution per slider, meaning, a 4*4*4 = 64 colors to choose from. Unfortunately, this results in several too similar colors and also too large value gaps / missing colors (such as grays, or a yellow skin tone).
