Makefile

#
# A Makefile that compiles all .c and .s files in "src" and "res" 
# subdirectories and places the output in a "obj" subdirectory
#

# If you move this project you can change the directory 
# to match your GBDK root directory (ex: GBDK_HOME = "C:/GBDK/"
GBDK_HOME = ../gbdk/

LCC = $(GBDK_HOME)bin/lcc 

# You can set flags for LCC here
# For example, you can uncomment the line below to turn on debug output
# LCCFLAGS = -debug

# You can set the name of the .gb ROM file here
