Lua Engine (Lutro)¶
Lutro is an experimental lua game framework that follows the LÖVE API. Lutro games can be played with LibRetro/RetroArch through the Lutro core.
How to start the Lutro core:¶
- As an example showcasing loading content with the Lutro core, we will load the Pong game hosted on RetroArch's Content Downloader.
You can do this by going to RetroArch's main menu screen and selecting 'Online Updater'. From there, select 'Content Downloader'.
- Select 'Lutro', then select 'Pong.lutro'. This should download and extract this file to RetroArch's Downloads directory.
- Go back to RetroArch's main menu screen. Select 'Load Content', then 'Downloads'.
If you are asked which core to select, choose 'Lua Engine (Lutro)'.
The content should now start running!
