@drdave79 For a minute I thought you were trying to extract a Naomi/Atomiswave rom and ended up with files in that naming scheme. Whoops! Glad you could figure it out.
@derekr resizing to 512x512 seems to have fixed a lot of the issues. Another one that I came across was that the ".PNG" extension of a couple of my files was capitalized. Make sure that your files use the lowercase ".png" extension.
@romhackfanatic Yeah bangai-o stuttering is usually a lack of bios. You just need to download the dc bios, create a dc folder in retropie's bios folder, and then put dc_boot and dc_flash inside it.
Aha! I see it was failing to find the BIOS - I didn't consider that because literally every other game has worked perfectly. dc_boot.bin and dc_flash.bin were both in there, but they were the wrong files. Have now replaced them and everything's peachy. Cheers for the tip :)
@mitu - Thanks a lot for the reply. I was pretty concerned this was a config setting I had stepped on somewhere. Sounds like it is just something I will have to deal with for now and maybe a future Flycast or Retropie build will address it.
-Sega Rally - Ran great
-Kiss Psycho Cirus - Ran around in the first room but seemed to be fine!
-Puzzle Bobble 4 - Playable but with a bit of slow down (it seems so simple too...)
-Super Runabout - Seemed to be full speed but with intermittent stutter.
However: i had no fun with DC on a Pi3(B).
A Pi4 should be highly recommended for this system.
Code Veronica is no CE Game and will work great. On a Pi4 :)
@greenhawk84 Sorry currently my pc has broken down so i backed up Retropie and installed Raspbean so i could continue to work from the home office, so all i got left for gaming momentarily is my RPI0 which i turned into a Sega mini :-(
@rva-818x-laystar The only game i found running better than its DC counterpart is Marvel VS Capcom 2
the rest either runs the same or worse in the case of Dead Or Alive 2
@iandaemon
I just found out someone posted an Alimentation Schematic/PCIB plan for it online for a USB version of it, but nobody bothered to make one yet for some reason:
