The PC Engine CD Autoboot patched BIOSes (available here: https://github.com/mathieulh/PCE_CD_BIOSES_NO_AUTOBOOT )
crash on this core.
They have previously been successfully tested on both real hardware and the MiSTer FPGA platform.
I could only test the NEC based revisions, I didn't have the chance to test the Games Express revisions of the BIOS yet.
UPDATE: The exact same issue occurs on the autoboot patches for the Games Express BIOS. (the original one works)
P.S. (AV Tanjou is having some serious graphical glitches on this core)
