(b) Unzip the source file. Create the build subfolder in /home/pi/ and copy all of the contents into this folder. Then make a new subfolder in this build folder called build (again).
(c) Use Putty, go to terminal and cd build and cd build (again), so you are in the nested build folder.
(d) To compile from source, type in the command in the terminal cmake /home/pi/build. Using GNU 4.9.2, the first stage of compiling the emulator will be complete.
(e) Then type in the command make. This creates the creatiVision executable.
(f) Once completed, rename the nested build folder to creativision and move it into the opt/retropie/emulators folder. You might need to change the permissions of the emulators folder to achieve this.
(g) Once moved, using WinSCP then change the permissions of the creatiVision executable file so that it is executable.
(h) In Attract Mode's menu-art snap and wheel folders, make sure there are videos and images corresponding to the new CreatiVision emulator. Make sure also in the layouts folder that there is a "system" to go with CreatiVision (see "Super Display - Systems" - things might need to be renamed too.)
(i) Create the usual file (immediately below) in Attract Mode's emulators sub-folder, and the "romlist" file in Attract Mode's romlists sub-folder eg
(j) Create a crvision subfolder in configs and the same in the roms folder. Add the game roms to the crvision roms folder and generate the romlist in Attract Mode in the normal way. (My romlist appears under (i) above). Make sure you have your snap and wheel sub-folders and images and videos in there.
(k) Add a Display in Attract Mode which will appear in attract.cfg:
display VTech CreatiVision
layout Super Display - Systems
rule Favourite equals 1
(l) The emulators.cfg in the configs/crvision sub-folder will be as follows:
