Switching between mega drive/genesis themes, etc

[ProxyCell]

I know that there is a method listed on the wiki on how to switch the theme being used in the es_themes.cfg file ( https://github.com/RetroPie/RetroPie-Setup/wiki/Genesis-Megadrive )

I remember a few weeks ago I saw a new commit to the github repo that apparently allows us to switch between PCEngine/TG16 and MegaDrive/Genesis via a new method. It appeared to be handled by an option in another file but I can no longer locate this. Would you happen to recall @herb_fargus ?

@ProxyCell from memory (not in front of PC) create a /opt/retropie/configs/all/platforms.cfg file with the line megadrive_theme="genesis" then reinstall a megadrive emulator.

Works the same for other systems.

Actually you should not need to create anything. You just need to edit the es_system.cfg file. I have emulationstation on my PC .. but I needed to know the location of the es_system.cfg in retropie....I changed mine and it worked fine but it brought down mega drive artwork. you have to change the system AND the theme tags to get that to work. here is how I did it from linux:

1. find the ip of your pi..(you can go to the retropie menu and choose show ip)
   on another computer that is connected to the same router type ssh -X (your ip here) -l pi press enter... (ex. ssh -X 127.0.0.1 -l -pi)

default password is raspberry
when asked to be added type yes..then press enter

(if you wish to use windows putty would be the way to connect to your pi..sorry I'm not familiar with it.)

from here on you are working in the pi!

2. now you want to navigate to the file..
   a. type cd / press enter
   b. type cd /etc/emulationstation press enter
   c. type sudo nano es_systems.cfg press enter
   d. once in nano press ctrl+w and type megadrive (or pcengine) press enter
   e. change the <platform>megadrive</platform> and <theme>megadrive</theme> to <platform>genesis</platform> and <theme>genesis</theme>

or for pcengine to turbografx-16 <platform>pcengine</platform> and <theme>pcengine</theme> to <platform>tg16</platform> and <theme>tg16</theme>

(basically you change what is in between the tags...leave the tags alone!

3. now press ctrl+x
4. press y to accept changes
5. press enter to keep the same file name
6. now type sudo reboot

wait for your pie to reboot and the changes should be there

here is a good video for windows users (linux users log in as above..the rest you can follow in the video):

note that not all themes have genesis or turbografx-16 (tg16) themes
there are some the don't have "arcade" themes but do have "mame" themes

@akafox editing es_systems.cfg is not the recommended method as you have to manually keep parity with any updates you make through the setup script.
