#THIS IS A "HOT" VERSON OF gba-dev.sh
#THIS ASSUMES THERE IS ONLY ONE .c FILE IN SAME DIR TO COMPILE
#DOES NOT PROMPT FOR FILENAME
#DOES NOT PROMPT FOR Y/N
#DEFAULTS TO ADDING TO PATH AND REMOVING .obj AND .elf FILES

#Designed for use with devkitARM toolchain.
#Developed on PopOs(ubuntu) 19.10 - 2020
#YMMV.

#This script needs to be in the same directory as the C file you wish to convert.
