Here's a dumper for 'Hikari No 4 Senshi', or as it'll probably be known here, 'The Four Warriors of Light'. Inside the ROM itself are files that have a header named SSAM. Those are what I call MASS files, probably for MASSIVE or the overall MASS or something, they're kinda redundant and seem to get in the way. Anyways, I've made a PHP file to quickly dump the MASS archive into something more workable. It's not a complex file format, and I'm sure if I was more awake I could do a nice C version that works well on Windows. As it stands, I've only tested this on my Mac. I know it'll have to be adapted for windows (mkdir, I'm looking at you). I'll get around to making a C version that does that and a repacker at a later time. Nonetheless, without further ado: http://pastie.org/674568 Hopefully this spurs some translations.

Extracted archive contents to common.dat_Files/ Right now it kinda sucks, too, as you have to manually edit the file to adjust the unpacking file. I kinda forgot to setup command line arguments.
