When they are missing demul states u are missing "mpr-xxx" I dont know why it names it that way, but there u go. u can see numbers at the end of each bios.each of those (1_01d_01.bin or similar) files represent the different bios and this is what ur looking for. in demul drop down menu -config, dreamcast bios. You are probably looking for something like 1_01d_01.bin or similar (found inside dc.zip, usually). To anyone finding this thread with similar issue its not actually a file named "mpr-xxxxxxx" that u are looking for, it is just that the emulator reads the bios file as this. I appear to have finally addressed he "unable to find mpr-xxxxx" issue with Demul, anyways at least. now, I don't get the msg but the game freezes on the sega/win CE screen.Īs someone who seems to know their stuff, im hoping this information might shine a light on any issue with my set up. The interesting thing is that before I renamed a copy as "boot.bin" i was getting the message when I launch the game about "this game needing a real bios". I saw another guide that advocated renaming dc_boot.bin as boot.bin, so i made a copy and renamed it, so now I have both (in both of said folders). My understanding is it shouldn't make a difference as retroarch scans subfolders, but anyways I covered both bases. I've seen some guides that advocate putting the bios in a specific dreamcast folder (i have it in "retroarch/system/" AS WELL AS "retroarch/system/DC/"). but that shouldn't matter for this game as their doesnt seem to be a game spcific file for the game im having issues with. just missing some of the optional ones(game specific ones like HoTD). ) As it happens, I DO have the correct bios for dreamcast. I think it will come in useful for some other issues i have (like getting naomi and atomiswave working. However, I never knew that particular way to check the bios, so iI really appreciate that. The issue, for me anyway, is just with Retroarch. One specific game that is facing this issue is jimmy Whites 2 - a lot for your reply. Is there a specific alternate bios needed for a handful of games? Is it possiblei have the wrong bios but it still works for some games?Īny help greatly appreciated. it works for other games, like sega rally 2. I HAVE what i believe is the correct bios. saying a "real dreamcast bios is needed for this game" (or something similar). So, hopefully that it is your issue solved.įor me, that is most of my problem solved but I still have this issue with a couple games that wont launch in flycast. I then converted it into chd (to save space) using chdman.i removed all other files except for the new chd file but kept it in its own folder and it still worked. When in its own folder the game worked in. bin format and had it in its own INDIVIDUAL folder (which was then inside my dreamcast roms folder, the folder i have set in redream as the library and where it should look for games. I tested one game by putting it back into. Ok so I think i've figuerd out one problem. Will get back to you with any discoveries. I will try them in their own folder as bin cue format and see if redream recognizes them, then i will try converting to chd again and see if they are still recognized. so, for the games that aren't working im gonna try that first. I just watched a video tutorial where a guy says the should each bein their own folder (even tho SOME games are showing up without being in their own individual folder). they went straight into the folder in that format. Currently the new games I added are in chd format. Theoretically, when using launch box/big box, it should launch straight into the game without showing the redream gui, but as the game isn't working it launches redream instead and shows the library, where most of the many of the games I added are missing. gdi and some in cue/bin format, at the time) ARE still working in their chd format but many of the new games adding many of them aren't showing in redreams gui. The WEIRD thing is that the games that were already in my collection and working (in. Mostly i noticed this problem after adding some new games and converting my entire collection to. Anyways my main issue is not just the wince games but in general now many games added to the folder (the same folder that is set for redream to look for roms) are not showing up in redream. others dont open at all, one opened and said "this game requires a real dreamcast bios, even tho I HAVE the bios in the system folder of retroarch (DCboot.bin). Most games im trying to run with redream, (the Win CE games im trying to launch with flycast core in Retroarch - on that note, Sega rally 2 runs fine in retroarch. Maybe if I scour the internet and try things we can find a solution together for our problems! Im also having big problems with this area. Im sorry to see you didnt get any replies on this.
