# Sanity check - JoEngine
#   1 - Execute `svn checkout https://github.com/johannes-fetz/joengine/trunk/Samples`
#   2 - In the ./demo1 path, modify the Makefile.
#       a. Remove the JO_ENGINE_SRC_DIR and COMPILER_DIR variables.
#       b. In place of the removed lines, add `SH2DEV=/opt/toolchains/saturn`. 
#       c. Change `include $(COMPILER_DIR)/COMMON/jo_engine_makefile` to `include $(SH2DEV)/COMMON/jo_engine_makefile`.
#   3.  Executing `make` should result in binaries and a CD image. 
#   4. To burn the image with k3b and to run with Mednafen, we need to modify the cue file further.  Execute `python3 /opt/toolchains/saturn/tools/binmerge.py game.cue fixed-game.cue`. 
#   5. Finally, execute `mednafen ./fixed-game.cue` to view the demo.

# Yaul is an excellent engine as well

# Sanity check - Yaul
#   1. Execute `source ~/.yaul.env` to load Yaul environment variables.
#   2. Execute `git clone https://github.com/ijacquez/libyaul-examples.git`
#   3. Within the newly cloned repository, in the `vdp2-zooming` folder, execute `make`.  You should have a good build.
#   5. Finally, execute `mednafen *.cue` to view the demo.

# Remove the temp build directory
rm -rf $TEMPBUILDDIR

Added Yaul...fixed...something?
