your rom is different than my working rom.

@crush Running Naomi/Atomiswave games is just like running an arcade game for MAME or FBNeo. Do not unzip the rom file itself. You should have a file called sfz3ugd.zip, and a .chd file called gdl-0002.chd. You would arrange it as follows, and then run the zip (As a warning, I do not have this particular rom to confirm, this is just as an example for a game that uses a CHD):
dreamcast
-sf3ugd.zip
-sf3ugd/gdl-0002.chdFrameskip of 1 is usually enough for me as far as I can tell. You are usually better off with Redream for Dreamcast games over Flycast, where possible. Unfortunately the Naomi/Atomiswave games won't work in Redream, unless you use the Atomiswave to Dreamcast conversions.
Additionally, your Naomi/Atomiswave games need to be from a MAME rom set. Other dumps will not work.

@g30ff i was replying to a post, i don't require help. but thanks.
PS: i recommend flycast over redream. -
@crush Sorry, my bad, I misread.

@mortalwombat said in Dreamcast, Atomiswave, and Naomi Performance:
Yep, still the same "Error 01: This Game is Not Acceptable By Main Board" message (I'm assuming by "the naomi roms folder," you meant the Dreamcast folder?).
Assuming I heard you right, I dropped a folder named " sfz3ugd" in there, containing the 109.2mb "gdl-0002.chd" file. And I'm aware that we may be getting our Street Fighter Zero 3 Upper ROMs from different sites-- neither of which we can discuss here-- but the 8.3mb "sfz3ugd.zip" file I have here, once opened (just to check if we're talking about the same ROM) produced a 36mb folder that contained:Oops, sorry, yeah the Dreamcast folder is the default Retropie folder for Naomi and Atomiswave roms ... which i did not like.
So, i manually created Naomi and Atomiswave folders ages ago as i only wanted Dreamcast Console Games in the Dreamcast folder
... and Naomi Arcade Games in the Naomi folder.<system> <name>naomi</name> <fullname>Naomi</fullname> <path>/home/pi/RetroPie/roms/naomi</path> <extension>.zip .ZIP .BIN .bin</extension> <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ naomi %ROM%</command> <platform>naomi</platform> <theme>naomi</theme> </system>Now onto file sizes ... sounds like we have a mis-match compared to my working game.
if i extract the sfz3ugd.zip then ... mine is not 36mb
Oh and the error... Error 01: This Game is Not Acceptable By Main Board
Could be caused by a bad BIOS ... i was getting that error on some games, re-downloaded a BIOS which was a different size and that fixed the issue.
The naomi_rem.zip was the original BIOS i was using ... and as you can see the BIOS i'm using now for Naomi (naomi.zip) is a larger file size
-
@crush I just left it at default, so I think 480? The problem is more like a glitch. If I play MK Gold or NFL Blitz, there is an odd jittery graphical problem. I really have to capture it to show what I mean.
-
@crush do you set any settings differently in Flycast in order to get the best performance? Redream just runs better for me IMO (Pi4 4GB).

@dreamcastkid said in Dreamcast, Atomiswave, and Naomi Performance:
naomi_rem.zip
@DreamcastKid appreciate your reply, my apologies for my own delay in noticing/responding as I haven't been too active on here lately (and have kinda been testing out other emulators/ROMs, but this-- and that unworking sfz3ugd.zip-- has been one issue that I've been meaning to get back to on here...).
So just so we're on the same page and there are no questions re: the Dreamcast/Flycast BIOS to get these NAOMI games to work (BIOS being yet another variable I've had to start wrapping my mind around here lately, since a lot of the console and arcade games I've come across thus far don't seem to use them), you're implying that the "naomi_rem.zip" one you mentioned IS an older one? (and thus probably no longer in use?). Because after you mentioned it there, I went Googling for it just now, but didn't seem to come across it.
I guess another thing I'm trying to understand is that a lot of these other emulators already seem to have their own designated folders where their BIOS files seem to go (and have recently started experimenting w/ the FDS/Famicon Disk System and ITS BIOS, which itself doesn't seem to have a designated folder for BIOS; so I wasn't quite sure if I was safe just dumping BIOS files-- like these Dreamcast ones, whatever the current/best one is-- in the general "BIOS" folder if there wasn't already a specified folder to file 'em in.
But yeah, this sfz3ugd.zip ROM I have is 95 MB unzipped (not sure if I missed how many MBs you said yours was?), with a 109.2mb chd file, annnnnd I just found/am currently DL'ing another chd file that seems to be 159mb... so again, part of the confusion is whether I have the right ROM/CHD combo.

@mortalwombat DreamcastKid is no longer a member of this forum.
@GreenHawk84 Any game in particular you got issues with? let me know and i'll record my settings and some gameplay so you can compare it for yourself.
-
@crush geez yeah belated reply on my part, not sure if I noticed that when I checked my notifications. Well, guess I'm getting no answers from him, but I may use this thread if I have any more questions about NAOMI Roms.
(side note, is the evidence/reason for the ban still posted for all to see? I'm always kinda morbidly curious about these things if only to know where the line is/was crossed, but I generally hope everybody's treating everyone with respect)
-
@mortalwombat all i know is that he deleted every single comment he ever made, which broke allot of helpful threads, then an admin restored the posts and he was banned. I don't know what started it.
All the bios files for Dreamcast and Naomi/Atomiswave go into "/home/pi/RetroPie/BIOS/dc"
As per your rom size and content regarding sfz3ugd, yours was different as mine and Dreamcastkid, i posted the results of my extracted folder above, for instance yours does not contain "93c46.bin" -
@crush I appreciate your willing to provide some results. Blitz 2001 (I think, maybe just any Blitz) and MKGold were giving me really odd graphic issues on Flycast.

Hey everyone. I just tried some NG.DEV.TEAM Dreamcast games with Flycast. Unfortunately, the core doesn't seem to work with the three that I tested (Gunlord, Fast Striker, and Gun Blade). I hear the volume, but no gameplay graphics appear (just a black screen). The same occurred with the Redream core (all on the Windows 10 x64 version of EmulationStation). Any ideas on what I can do to fix this issue? Thank you.
-
@striderx99 Sorry, but Gun Blade should be Ghost Blade, and that particular game is from Hucast Games.
-
@striderx99 cannot speak for flycast, but can confirm that all three named NG:DEV-Games run pretty well using lr-flycast.
Also running: Neo XYX & Last Hope: Pink Bullets -
@greenhawk84 Sorry currently my pc has broken down so i backed up Retropie and installed Raspbean so i could continue to work from the home office, so all i got left for gaming momentarily is my RPI0 which i turned into a Sega mini :-(
