Images

Introduction

Creating art for the Sonic 1 J2ME engine is fairly easy as the art doesn't use tiles like a conventional 2D game, rather using simple PNGs.

Sprites and Frames

Single frame sprites can be extended and modified in nearly any way without effecting much. Multi frame sprites (i.e the player) use a single image for all the frames for animation, and as such have boundaries for what can be drawn in a single frame. As of April 2020, how one is to edit an image's frame bounds is unknown. But it most likely lies in either b.class or c.class, perhaps "Frame Data.bin".

Colors

Art is primarily drawn with either 4-bit 16 colors, or 8-bit 256 colors. Images are not limited to these colors however, 24-bit full color is possible, but at the cost of transparency.
