floodie Posted October 9, 2019 Share Posted October 9, 2019 Hi guys. Just bought big box. Its great. However when trying to play naomi i have a few probs. One is a caution 51 error and the game wont load. I can see a tutorial on how to solve, im meant to goto the service menu. I can get into the service/test menu but i just cannot navigate to anywhere within it!!! Secondly, Ikaruga was trying to play horizonally. Managed to find how to switch it to vertical which worked however its upside down. So instead of shooting up the screen im shooting down. How can i flip it??? Sorry and thank you!!

Retro808 Posted October 10, 2019 Share Posted October 10, 2019 Demul should have a "Rotate" option in the menu. Run Ikaruga and then go into the Demul video options. I think my setup shows it set to 270. Quote Link to comment Share on other sites More sharing options...

floodie Posted October 10, 2019 Author Share Posted October 10, 2019 I did pull this up before but to be honest didnt understand it. Had another read and theres a few red herrings to update. The answer seems to be a lack of a chd file. In my games/sega naomi/ folder i dont have chds but rather .bins. Are they saying delete these and paste in the ikaruga.chd files instead??

floodie Posted October 17, 2019 Author Share Posted October 17, 2019 hi guys - any further help on this? Quote Link to comment Share on other sites More sharing options...
sundogak Posted October 18, 2019 Share Posted October 18, 2019 See here on instructions for Flycast core. For games that need CHD files you need them as well and they need to be in path structure that the core wants to see. Snip from the instructions: How to play NAOMI Games:¶ Run NAOMI games stored in MAME format zip files by following the same process as standard Dreamcast games Run NAOMI GD-ROM format games stored in MAME zip + chd format by running the zip file through RetroArch. The zip file should be stored in your roms folder with the chd file in a subdirectory of the roms folder named after the mame ID. Example (MAME ID=ikaruga) - [ROM FOLDER]/ikaruga.zip - [ROM FOLDER]/ikaruga/gdl-0010.chd Quote Link to comment Share on other sites More sharing options...
