Saturn 4bpp Graphics Converter

A utility to convert between SEGA Saturn 4bpp graphic format and bitmaps.

After dumping both a 4bpp graphics file and its corresponding palette file from a SEGA Saturn game and identifying its dimensions,
  
4bpp-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 4bpp graphic format using
  
bmp-2-4bpp
.

Current Version

Saturn 4bpp Graphics Converter is currently at version 1.0....

Usage

Note that the output filename of
  
4bpp-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
).
Code: 
  
4bpp-2-bmp <4BPP_FILE> <PALETTE_FILE> <PALETTE_INDEX> <WIDTH> <HEIGHT>
Note that the output filename of
  
bmp-2-4bpp
 will be the input filename with the
  
.BMP
 extension removed (e.g., an input file named
  
TEX.BIN.BMP
 will produce
  
TEX.BIN
).
Code: 
  
bmp-2-4bpp <BITMAP_FILE> <PALETTE_FILE> <PALETTE_INDEX> <WIDTH> <HEIGHT>

Example Usage

Convert a 64x16 4bpp graphic file named
  
TEX.BIN
 to bitmap using the first palette index (i.e.,
  
0
) from palette file
  
TEX.PAL
.
Code: 
  
4bpp-2-bmp TEX.BIN TEX.PAL 0 64 16
Convert a 64x16 bitmap named
  
TEX.BIN.BMP
 to 4bpp graphic format using the first palette index (i.e.,
  
0
) from palette file
  
TEX.PAL
.
Code: 
  
bmp-2-4bpp TEX.BIN.BMP TEX.PAL 0 64 16

Tutorial

Malenko... published a fantastic tutorial on ripping and replacing SEGA Saturn graphic assets on the SegaXtreme... forums. It also details how to extract palette data. Click the preview screenshot below to access it.



Note that Malenko also created a guide on the usage of the Saturn 15bpp Graphics Converter..., which may prove helpful to those wishing to use Saturn 4bpp Graphics Converter.
