gupti99 Posted April 2, 2018 Share Posted April 2, 2018 Hi, After following the Demul Launchbox YT setup video step for step I am at a point where I get the following error if I try to start a DC game: "Unable to find set5v1.001.ic507" I have the DC bios's in the BIOS folder and my DC games are all in .zip format. I have tried many different fixes to try resolve this issue but none have worked. Has anybody had this issue before? Thanks alot! Quote Link to comment Share on other sites More sharing options...

gupti99 Posted April 2, 2018 Author Share Posted April 2, 2018 Thanks for the quick reply! I have all the relevant bio's. I have even tried grabbing them from different sources in case the zips were corrupted but I still get the error above even if I try "Run Dreamcast" from Demul itself and not via Launchbox Quote Link to comment Share on other sites More sharing options...
rexryan Posted April 2, 2018 Share Posted April 2, 2018 The error it's showing is a file inside to DC bios check to see if it is there or named incorrectly Quote Link to comment Share on other sites More sharing options...
gupti99 Posted April 2, 2018 Author Share Posted April 2, 2018 It is not in my dc.zip file. I have acquired a number of dc.zips online from various sources and none of them contain this missing file "set5v1.001.ic507". . Out of interest and I am not asking for anyone to share it but can you confirm that you have this missing file in your dc.zip? Thanks Quote Link to comment Share on other sites More sharing options...

gupti99 Posted April 2, 2018 Author Share Posted April 2, 2018 (edited) I managed to get the DC roms running in Demul however I have a questions about my Japanese Naomi games which I cannot run. 1) I have a load of Naomi roms however they are in zip format. Each zip containing A gdi file and some additional bin and raw files for example. I cannot get the games to run. Does the GDI file need to be extracted for Naomi games and if so what about the additional files in the zip? 2) When I try to run a Naomi game I get this error However I have 2 Naomi bios zips in place. Is this likely an issue with the bios or game roms? Edited April 2, 2018 by gupti99 Quote Link to comment Share on other sites More sharing options...
DOS76 Posted April 2, 2018 Share Posted April 2, 2018 If you have a full MAME ROM set you would probably be better off using those instead of the files you have Quote Link to comment Share on other sites More sharing options...
gupti99 Posted April 2, 2018 Author Share Posted April 2, 2018 Unfortunately I dont have a full mame romset at the moment. Quote Link to comment Share on other sites More sharing options...
