DOS76 Posted October 17, 2017 Share Posted October 17, 2017 I would suggest getting the latest DC.zip file from a MAME non-merged set and adding it to where ever your Demul ROMs are the file has under gone changes recently in MAME. Quote Link to comment Share on other sites More sharing options...

Lordmonkus Posted October 17, 2017 Share Posted October 17, 2017 It has the bios that you are missing. You don't need to get the Mame set but you will need to look around for the missing bios. Quote Link to comment Share on other sites More sharing options...

Lordmonkus Posted October 17, 2017 Share Posted October 17, 2017 I can't remember if they need to be unzipped or not. I have them both zipped and unzipped in my DC bios folder. Quote Link to comment Share on other sites More sharing options...

Lordmonkus Posted October 17, 2017 Share Posted October 17, 2017 It can be anywhere you want but you have to tell Demul where to look for it. 1 Quote Link to comment Share on other sites More sharing options...

DOS76 Posted October 17, 2017 Share Posted October 17, 2017 What MAME has to do with Demul is that it uses the same exact ROMs and BIOS files depending on your version of Demul will depend on which version of MAME files it is looking for.

lino11 Posted October 21, 2017 Share Posted October 21, 2017 Hey Lordmonkus, I was having a similar issue as the original poster trying to get Atomiswave going, HOWEVER.... I think mine can be fixed with some command line help, perhaps. First off, I have Demul running fine... I have Dreamcast games running flawlessly through Launchbox. For DC, I can click on a game from my Launchbox library page and it'll load up and play fine. For Sammy Atomiswave, if I click on a game, it just opens up the Demul program. Nothing else. Now, if I go the program's preferred route, and put my Atomiswave games in the emulator's root ROM directory, then everything works great. Open the app, run the game. Easy. So I know my BIOS stuff and plugin mapping is all good. But that's using Demul outside of Launchbox. And I got all my games on an external hard drive, and want to use it through Launchbox.... since it's so pretty and nice to me. What am I missing here? Things I've tried: 1. I created a 2nd Demul in LB... I called it "Demul [Arcade]" -- I hope to run all those sega ones thru here, naomi, naomi 2, gaelco, hikaru, cave... what else? For now, only regular dreamcast games work for me. 2. I've got the standard Associated Platform stuff set up and set as default, with this command line: -run=awave -rom= 3. I've tried a series of combinations of "don't use quotes" and "no space before ROM" and "use file name only w/o extension." With one of those combos, I get a similar error like the OP up top, "unable to find mpr-2193.ic501 in romset awave" or whatever it is... Thanks for any help!!!

Lordmonkus Posted October 21, 2017 Share Posted October 21, 2017 You will need to add the rom locations in Demul and then you will want the appropriate command line parameters for each platform. Here is the command line for Atomiswave which is the only one I use aside from Dreamcast. -run=awave -rom= Quote Link to comment Share on other sites More sharing options...

lino11 Posted October 21, 2017 Share Posted October 21, 2017 It's weird because I can get Atomiswave working fine. It works, plays perfect. Under these conditions: 1. Open Demul outside of LB 2. Copy each atomiswave game to root rom directory So my bios must be correct, right? However, if I try to run the game "demofist" (Demolish Fist) through LaunchBox, I get this: Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted October 21, 2017 Share Posted October 21, 2017 Ok well that error tells me that your Demolish Fist rom is no good. You don't need to copy your roms to the root rom directory, you can simply tell Demul where to look for the roms and you can add multiple paths like how I have in the screencap above.

lino11 Posted October 21, 2017 Share Posted October 21, 2017 Thank you!! You know, I didn't realize that I could have more than one path for "roms and bios" .... but that's obviously what "add" means there on the gui. Doh!! I had my bios folder separately from my games folder, so I was only pointing the program to the one folder, not both. It's working now through Launchbox!! And Demolish Fist works! (odd though, that it gives that particular error msg, even when you can clearly see that ax0601p01.ic18 file inside the zip contents) Thanks for your help, sometimes just talking it out can do it. Have a nice weekend! Quote Link to comment Share on other sites More sharing options...

DOS76 Posted October 21, 2017 Share Posted October 21, 2017 yeah some time the content of the .zip file will change as they will get a better dump of a machine or figure out how to implement something else on the board that previously didn't work. The latest version of Demul from the 12th of this month uses the latest MAME ROMs so depending upon which version you have you may have to source the roms for that version.
