Hi guys,
I'm new to Sega Naomi Emulators especially Demul and I need your help. I followed the tutorial about Naomi games, downloaded a non merged 0.185 MAME romset and use the batch files to extract Naomi, Naomi2, Naomi GD, Naomi 2 GD, Gaelco, Hikaru, Atomiswave ROMs to differents directories.
1) In Demul, only Atomiswave games are working. For example, I get a load file error with Dead or alive 2 (Naomi); "Unable to find 'epr-21576d.ic27' in romset 'Naomi'". I don't understand because I added all my ROMs directories in Plugins, Maple & Paths. What did I do wrong?
2) Do I need any CHD to play the Naomi games?
Hi, welcome aboard. I am also working on Sega arcade systems atm
1- DEMUL requires different commands for different systems, so make sure your emulator.cfg files is using the correct commandline:
-run=awave
-run=cave3rd
-run=gaelco
-run=hikaru
-run=naomi
2- You will need chd files for roms which need it CHD folder should be named as the rom-name (few exceptions) like for a rom named pac-man.zip chd folder should be named pac-man and be placed in the same folder as of rom. Use the follwoing db website:
http://adb.arcadeitalia.net/
and search by inputting the filename. Scroll down to files and expand "Show Mame required files" to check if any .chd is listed (the chd folder name will also be listed). The CHD tag below the game picture on top will also be highlighted.
DEMUL:
1- Make sure to use the new gpu vid driver in plugins. Some games will crash while using old (specially naomi 2). Once you are sure the games/ systems work you can then switch to old as required.
2- Open Demul.ini in demul folder. Scroll down to [files] section. Make sure all paths are listed and make sure that "romsPathsCount = 3" is updated to show the actual number of paths. Demul will only check path# which are in "romsPathCount" so if PathCount is say 2 demul won't check any rom paths exceeding 2.
