Damn haha.
Those are some painful playlists to watch
I'd recommend you do the playlists manually if you could.
For example, let's start by creating a LPL per core.
You can get the name the LPL file needs from this list:
https://github.com/libretro/libretro-database/tree/master/rdb
In there you will find the
exact name that you need to put for the kind of console the game is for.
Let's say you want to create a Game Boy family playlist, then you need to create a file with the following name:
- Nintendo - Game Boy.lpl
- Nintendo - Game Boy Color.lpl
- Nintendo - Game Boy Advance.lpl
Now, once you have a file for each Game boy console, you open the lpl file with any text editor, let's say Notepad, Notepad++, Gedit, etc.
You will follow the next table as an example:
As you can see, making a playlist file is pretty easy.
You can even combine several consoles which can boot with one core in one simple playlist file, for example you can boot anything from GB/GBC games to GBA with mGBA, then you would simply add the .gb and .gbc games to the GBA LPL and that should be it!
