Raposa do Sol SMS

This is a Sega Master System game "inspired" by the Atari 2600 game Solar Fox. "Raposa do Sol" means Sun Fox in pt-br.

Coded by tibonev

using the SMSDevkit by sverx

also using sms_fxsample by kusfo

and pcmenc by Maxim

levels designed using Tiled

music done using Furnace

compiled using SDCC

To build it, you need a working copy of SDCC and SMSDevkit, with crt0, lib(SMSlib) and PSGlib inside their own folders, relative to main.c, if you're in a windows enviroment, then all you need to do is run build.bat. Otherwise you might need to execute the commands yourself.

There's a PHP companion tool, to convert Tiled's CSV output to C Array used in the code.
