Saturn 15bpp Graphics Converter 1.0

Saturn 15bpp Graphics Converter​

A utility to convert between SEGA Saturn 15bpp graphic format and bitmaps.

After dumping 15bpp graphics from a SEGA Saturn game and identifying its dimensions, 15bpp-2-bmp can be used to convert said graphic data to a bitmap for editing. After editing the bitmap, it can be converted back to its original 15bpp graphic format using bmp-2-15bpp.

All transparent pixels from a 15bpp source graphic are turned into magenta (#FF00FF) once converted to bitmap. Likewise, this color will be treated as transparency when converted from bitmap back into a 15bpp graphic.

Current Version​

Saturn 15bpp Graphics Converter is currently at version 1.0.

Usage​

Note that the output filename of 15bpp-2-bmp will be the input filename with the .BMP extension appended (e.g., an input file named TEX.BIN will produce TEX.BIN.BMP).

Note that the output filename of bmp-2-15bpp will be the input filename with the .BMP extension removed (e.g., an input file named TEX.BIN.BMP will produce TEX.BIN).

​
