I hope this will help you and others and now. I also tried with IKARUGA, VTENNISG, MONKEYBALL and tehy worked ! Now you can RUN the game from DEMUL (the CHD plugin doesn't seems to be used!) Copy the MAME rom 'vtennis2.zip' into the DEMUL rom folder, add the 'vtennis2.bin' into this archive.Ħ. Delete 'decrypted vtennis2' and rename 'encrypted vtennis2' to 'vtennis2.bin'ĥ. In the current folder, you'll find two new files 'encrypted vtennis2' and 'decrypted vtennis2'Ĥ. Exit MAME after the rom loading screen.ģ. Run 'Virtua Tennis 2' with the debugger version of MAME -> MAMED.EXE VTENNIS2Ģ. Then here is how to proceed to get the correct DEMUL rom and run it :ġ. I'll take as example the game VIRTUAL TENNIS 2ġst, you need the lastest version of MAME (0.130U4) compiled in debugger mode (MAMED.EXE)Ģnd, you also need the proper MAME roms and CHD for that game. Here is step by step how I got them working. I managed to get the GD-ROM games working in lastest DEMUL ! Whenever I choose 'Play' with the joypad, the screen goes white for half a second, then the 'Play/File/Music/Settings' screen appears again.

This time the Dreamcast BIOS booted and reached the 'Play/File/Music/Settings' screen, while on the top of the window, the words NAOMI_GDROM_IKARUGA appeared.

opened the ROM selection screen from File->Run NaomiĪnd I got an error message: 'Unable to find ikaruga.bin inside ikaruga.zip'įor the second test, I did the following: selected the file gdl-0010.chd from Config-GDROM

selected the gdrCHD plugin from the menu Config->Plugins I made 2 tests with the Ikaruga CHD (a file called gdl-0010.chd and a zipped file called ikaruga.zip containing a file called ). I see that Demul has a plugin to load CHD games, but what is the correct procedure to load and play them?
