petebuster Posted May 16, 2021 Share Posted May 16, 2021 I am running Demul to emulate a number of Naomi games. On its own on they run fine. When trying to launch Demul via LaunchBox Naomi gives an error of "ERROR 01 THIS GAME IS NOT ACCEPTABLE BY MAIN BOARD." My emulator setup has the 'No space before ROM' checked. Under associated platforms I have the following: Associated platform: Sega Naomi Default command-line parameters: -run=naomi -customrom= Default emulator is also checked. What am I doing wrong?

Guest Posted May 16, 2021 Share Posted May 16, 2021 (edited) Usually that error is due BiOS region mismatch. I get it only if I try to run an Arcade Japan game selecting an Export BiOS ? Anyway, in Details tab tick the option "Use file name only without file extension or folder path" As Default Command Line Parameters use -run=naomi -rom= ( type that in Details tab Default Command Line Parameters too ). The command you are using is for roms that are not listed in DEmul ( I use it just for a few Atomiswave games ).
