Tutorial: SKyscraper 3 custom system video and image alternative way.

[polobear31]

After i made a post regarding scraper platform not being set i figured another way to scrape for custom systems.

assuming you already added a new system

<system>
    <name>mortall</name>
    <fullname>mortal kombat</fullname>
    <path>/home/pi/RetroPie/roms/kombat</path>
    <extension>.7z .cue .fba .iso .zip .7Z .CUE .FBA .ISO .ZIP</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ mame-libretro %ROM%</command>
    <platform>arcade</platform>
    <theme>kombat</theme>
  </system>

create a roms folder

**/home/pi/RetroPie/roms/kombat**

next we going to be using mame-libretro roms folder make it empty and put your roms in here.

/home/pi/RetroPie/roms/mame-libretro

now press F4 and select skyscraper and scrape only mame-libretro,after scrape is done move on to the next step.

go to

/opt/retropie/configs/all/emulationstation/gamelists

create a empty folder name it mortall
now go to this path

/opt/retropie/configs/all/emulationstation/downloaded_media

create a folder name mortall
go to mame-libretro folder in same path copy all content to mortall

now open

/opt/retropie/configs/all/emulationstation/gamelists/mame-libretro

copy gamelists.xml to

/opt/retropie/configs/all/emulationstation/gamelists/mortall

open the gamelists.xml in pc edit the path and upload it.
your done,restart and check.
after you are done just delete all content in

/opt/retropie/configs/all/emulationstation/gamelists/mame-libretro
/opt/retropie/configs/all/emulationstation/downloaded_media/mame-libretro
/home/pi/RetroPie/roms/mame-libretro

this will work for all other systems.
