I've found the answer! I'd set my Video Output in Retroarch to Vulkan, it looks like for the games to work (specifically) via Launchbox that I need to change the Video Output back to D3d12. I'd guess that when running games directly through Retroarch the video driver (this might not be the right terminology?) is adjusted to something other than Vulkan, but when using Launchbox it'll only use the one saved in the Retroarch config file? Retroarch Video Output can be found in Settings --> Video --> Output --> Video I'll have a look to see if there's any way to have a per core video driver (again, sorry if this is the wrong terminology) and report back here if i locate a method.

Hi all, I've got a bit of annoyance at the moment and wondered if some kind soul could help me out. I have Launchbox and Retroarch installed and working just fine for most formats, however, noticed a short time ago that Dreamcast and Naomi 2 CHD games just will not load via Launchbox through Retroarch Flycast. The games run just fine though Retroarch directly using the Flycast core. Naomi 2 non-chd games work just fine, Naomi chd and non-chd games work just fine. Dreamcast games are in .chd format with a couple of .cdi files both formats aren't working via Launchbox. I can get the Dreamcast / Naomi / Naomi 2 games running via Launchbox through standalone Flycast and Redream, so it's not the end of the world, just an annoyance. I'm also having issues launching via Demul in Launchbox, but have found this historically finnicky at the best of times, so I'll do some more research and try and resolve that myself separately - fixed Demul! needed the default command line and a tweak to the Running Script. Can anyone offer any suggestions on how to get these games booting via Launchbox through Retroarch Flycast? Let me know if you need any screenshots of my emulator setup pages etc. Thanks, Grim.

Hiya, I've just got Ferrari f355 running on Demul through Launchbox, I have the latest current MAME Split Set 245. My error message was something like 'unable to find epr-21863.ic27 in romset 'naomi'. The way I got it working was to find the missing file - I found it in f355dlx.zip - then pull it out / extract it from the zip file and add it to naomi.zip. I use Winrar and could just drag epr-21863.ic27 onto my desktop from f355dlx.zip (then closed winrar), double clicked naomi.zip and dragged the file into the archive. Ferrari runs after that, but it seems to open 4x iterations of Demul, this might be normal (maybe the original machine had 4x seats?) but I've not played it to any great degree before. I also had trouble with House of the Dead 2, I had to pull the file epr-21330.ic27 from hod2bios.zip and also add it to naomi.zip. The game runs fine after that. If I find any more games that are missing files I'll try to remember to come back here and update the post. Good luck!
