A little about my build, in case any of it could be related to my problem. I got a Japanese VA1 with no GD-ROM from eBay, put it in a clear reproduction case with DreamPSU, Noctua fan, battery mod and GDEMU 5.20.5. Formatted a 512 GB Micro Center Micro SD card and loaded a large GDI collection of NTSC-U, NTSC-J and PAL games using GDMENU card manager. It was set to shrink the GDI’s and skip the blacklisted titles and included OpenMenu. Connected to TV with Kaico HDMI converter and, after setting the time it booted into OpenMenu.
When I select a title, and press “A”, I get the Dreamcast splash screen and then it goes to the Dreamcast main menu. The first title was Half Life so I thought it may have been compiled incorrectly, but I tried about 6 games from all 3 regions and they’re all doing the same thing.
Any suggestions?
