First one a fresh retropie install via Raspberry Pi Imager updated (including OS) and configured (config.txt, static ip for eth0, diabled wifi/bluetooth, enabled ssh, etc.) and the second one added the emulators (installed from binary) to it. To avoid messed up configurations due to too much *interfering leftovers" from my tinkering, two base images where created as fallback solutions.

In this post I will cover the basic setup and sources used. In the "Development of module-script generator for lr-mess, lr-mame and mame standalone"-thread I had said that I am eventually making a showcase-thread about this, so here it is.Īs AFAIK this forum still lacks the markup option for folded paragraphs (though it is cabable of folding quoted parts (sigh)), I will split my "opening post" into multiple ones. Recently, I wanted to try out some of nowadays options for vector arcade games available within retropie to see what may be is/could be suited to be used on my wall mounted pseudo-cabinet and whilst I was at it, I decided that I also wanted to play/experiment with mame backdrops used in conjungtion with libretro overlays. ![]()
