Don't share copyrighted material here. A note in PCEHawk's source says that 384 KiB roms should be padded to 512 KiB in a specific way: the first 256 KiB, followed by another copy of the first 256 KiB, followed by the last 128 KiB. Doing that makes the game load properly. You might also need to copy the gamedb entry as it sets the BRAM option.
Thank you for your guidance! Everything worked out fine after I added the entry in GameDB.

There is a PCE game, NEUTOPIA1, with an original ROM size of 384KB, which runs normally on BizHawk. For the purpose of hacking, I padded it with FF to expand it to 512KB, without making any other modifications. It runs fine on RA, Mesen, and Mednafen, but on BizHawk, the title screen is glitched, and the opening sequence freezes. I am unable to determine the exact cause, and the debugger doesn't show any abnormalities. PCE games shouldn't require any header modifications, so I'm not sure why simply expanding it to 512KB causes issues, especially since other emulators display it correctly. http://www.emugif.com/tmp/ghost/img/t0.jpg http://www.emugif.com/tmp/ghost/img/t1.jpg http://www.emugif.com/tmp/ghost/img/t2.jpg
