To avoid messed up configurations due to too much *interfering leftovers" from my tinkering, two base images where created as fallback solutions. Raspberry 4B 4GB (early rev., 1.5MHz, not benefiting from arm_boost 1)įresh install of retropie 4.8.3, hdmi-group 1, hdmi-mode 16 (1080p) set in config.txtĮmulators used: mame/lr-mame (0.251), lr-mame2016, lr-mame2003-plus, advmame, FBNeo (core version v1.0.0.03 72b9d1e) It will be followed by some (brief) reports/presentations about a few observations made so far and finally, in my last post (for now), I will elaborate a bit on my experience gained and formulate some questions that arose during this venture. 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.
