And i wanna try to give it this look, basically i need to modify sprites.
I've tried to search around the internet to find a program to do it, and i stumbled upon turaco, which is this nifty program that lets you export sprites and import sprites to modify the game. It has 840 predefined drivers, which are INI files that read instantly where the sprites are stored and the palette. it's on DOS, but it's not difficult to use.
Sadly there's no driver for Kaneko, and so no driver for Samurai Nihon Ichi. Is there another program which can extract the sprites and can hack the games, or... is there someone among you that can help me to write a new INI file? I suppose it has to start from the C++ file?
