# For sanity check, :
#   1 - Run `git clone https://github.com/XaviDCR92/psxsdk.git`
#   2 - Within the Makefile.cfg file, change the value of the TOOLCHAIN_PREFIX variable to match 
#     the value of the PSXDEV near the beginning of this script (i.e., /opt/toolchains/psx).
#   3 - In the root of the psxsdk repository, execute `make && make install`.  
#   4 - Next, let's change our current path by running `PATH=$PATH:/opt/toolchains/psx/bin:/opt/toolchains/psx/tools`
#   6 - In ./examples/puzzle, execute `make`.  Should run with no errors.
#   7 - To check with an emulator, execute  `exec wine "/opt/toolchains/psx/tools/epsxe/ePSXe.exe" "-loadbin" "puzzle.iso" "-nogui"`.
