(4BPP SMS/GG/WSC) Neo-Geo Sprite Converter (Version 1.0)

by AJ/freem (http://www.ajworld.net/ and http://freem.co/)

==========================================================

[Information]

This program converts 4BPP Sega Master System/Game Gear/WonderSwan Color tiles

to Neo-Geo sprite tile format. It should be noted that the output format is not

suited for immediate use with either cart or CD.

"Why SMS/GG/WSC", you may ask? The format is close to the Neo-Geo sprite format,

unlike the SNES (for which tools exist already).

(I wrote this tool since I was tired of decode16/recode16's interactive mode UI.

No disrespect intended; I just prefer to pass parameters in on the command line.)

================================================================================

[Usage]

neosprconv (infile) [outfile]

outfile is optional; if omitted, the default filename is "outfile.c0".

================================================================================

[Conversion]

I noted above that "the output format is not suited for immediate use with

either cart or CD". Depending on what system you're targeting, you're going to

need to perform a different task.

(Converting to Cart)

Cart systems have the .c# ROMs, where each odd-numbered file has the first two

bitplanes, and the even-numbered files have the second two bitplanes.

To convert a "outfile.c0" to the numbered C ROMs, you'll need a program that can

split files by words (each two bytes). ROMWak can do this with the /w option.

(Converting to CD/.SPR)

CD systems use a .SPR file, so you're halfway there.

All you need to do is byteswap the output. Yes, it's that simple.
