Dreamcast, Atomiswave, and Naomi Performance
-
@darksavior so I figured out part of the performance drop off in redream. The visual effect for the sun in the sky is causing slow down in multiple games. As soon as the sun is off screen the games go back to fullspeed. I reported on gitlab so hopefully it's an easy fix.
-
I was messing around with Redream trying to get the 4:3 to display properly, and it was working good when I changed the resolution to other oddball numbers like 720x400, etc. But then it started crashing back to ES when I made too many resolution switches to test and see what looked/ran best. Now it seems to have broke Redream from changing any resolutions altogether. If I go to the menu and change it, it just crashes on everything. I tried to uninstall/reinstall thinking maybe a file got corrupted, but it remembered everything I set before, so something is sticking in the installation even upon uninstall. I happen to really like Redream performance, I feel it is superior to Flycast. Although I do not like that it doesn't use Retroarch so I cannot set overlays etc. I wish Flycast had the performance that Redream does. I am actually shocked I was able to get Soul Calibur running smoothly in 1280x720! But alas, now I have a new problem :(
-
Doing some testing with Flycast, it appears some games may not play nicely with Threaded Rendering/Synchronous Rendering. When I disabled it for Mortal Kombat Gold, the "screen tearing" or "game tearing" (sort of an odd visual glitch) went away and it played like butter. So I tried to do a Game Override, but apparently that does not hold for Retroarch "Options" settings. The potential is all here, but not quite there yet IMO.

Metal Slug 6 runs good enough for me using lr-flycast (1st boss slowed down badly on an old version, but is much better now)
Thanks this has been very beneficial for me, turns out i had to update my Flycast core as well it is so much better now.

@greenhawk84 Uninstalling Redream doesn't clear out its config files, unfortunately. To get rid of your configuration, go to /opt/retropie/configs/dreamcast/redream and delete redream.cfg. You will also lose custom controller mappings you've set up.
If you can't adjust the aspect ratio of your screen, you'll need to mess with the window size in Redream. I don't advise trying to increase the internal resolution (assuming you bought a Redream license), because the Pi can't handle upscaling beyond the native 640x480 resolution.
-
@g30ff yes, that was the setting, "Window Size." I was changing that and getting the games to display properly on my 1080p monitor. Thanks for the tip!
-
@g30ff Are you sure about that? There are some games, that seem to work well with 1280x960 internal resolution. So far I have just tried Ikaruga and Rez, but at least the first level seems ok to me. I have the latest stable release (1.5.0) installed . The dev releases are somewhat slower, especially on higher resolutions.
-
@ecto Less demanding games should be okay, but some of the more graphically intense games will have problems. I don't have a Redream license to test higher internal resolutions, so take what I say with a grain of salt. It's just based on what I've seen others say on other threads or discussions. I have the latest development build installed, since that's what gets installed through RetroPie-Setup, and because it supports the Atomiswave conversions.
-
@g30ff Yeah, It's true what you say. More demanding games will not work with higher internal resolutions. That's why it's quite interesting that Rederam now supports per-game-configs. The downside is, that this feature is only introduced in the dev builds, which are somewhat slower...
All in all I'd say that registered version with the higher resolutions probably only pays off on faster hardware! -
Hello, I was able to delete the Redream .cfg file in the configs folder and it fixed my problem for Redream crashing on any resolution change. Now this has become a matter of using Flycast or Redream as my core of choice. I really wanted to use Flycast for those overlays.. but the performance is still having trouble. I will try to capture what I am seeing on some videos.

What internal resolution are you using in Flycast? performance should be good at 480p for most games.

Hey all, apologies for my chiming in late here, but I too have been trying to get some games that I guess are NAOMI to work recently without success (Marvel VS Capcom 2, Capcom vs. SNK: Millennium Fight, Giga Wing 2, Sega Strike Fighter, Street Fighter Zero 3 Upper, I think Rave Racer may have been one of them too; I don't recall any of these being listed on Roslof's spreadsheet of ROM/emulator compatibility which is what I usually consult).
Frankly I'd never even heard about NAOMI before, but had noticed that most of these games-- if they loaded at all-- were running SUPER slow and jerky, often with none of the controls even working, and that NAOMI logo at the beginning seemed to be a common denominator.
I'm also on a Pi4 w/ 4GB (I'm too much of a noob to even know how to overclock if I wanted to, but if that's pushing the limit of even being able to run these games please let me know). I was about to post on here looking for tips before I searched & stumbled across this thread.
Thing is, I'd been trying to run them off all the arcade emulators I currently have (Mame and FBNeo), and thought there might just be a BIOS or CHD file missing for these (not that I'd know yet where to find or file such files were that even the case).
Am I to understand based on what I've seen so far that the experimental/optional lr-flycast package is the best (or only) RetroPie emulator that can play these?
I'd come across this list of others while Googling (DEmul, NullDC etc), but figured they were either outdated, desktop apps, or simply not available on the RP...

@mortalwombat lr-flycast is the only emulator on the Pi 4 that can support Naomi or Atomiswave games. Your best bet is to turn on frameskip in the core options to get them to run smoothly. The Naomi and Atomiswave are basically Dreamcasts that have been modified (and in the case of Naomi) upgraded for arcade hardware. The best emulator for Atomiswave/Naomi games is demul, but that's Windows-only.
-
@g30ff really appreciate the reply! Yeah DL'd it (tho in binary mode, not from Source, not sure if it makes a difference w/ its performance?) and ran a few of the games mentioned above. Yeah, they all ran-- but shaky, with the audio slowed down too-- until I went in and adjusted the Frameskip like you said, and they all seemed to work a lot better (though w/ Giga Wing 2, there's already so much going on on the screen that it's nearly impossible to follow). Btwn. 1 and 6, I just set it to 1. Is there a different number you'd suggest??
So I guess this means that I can run other Dreamcast titles? (though I'm guessing they may also have the Frameskip issue?).
A few other questions though:
-
I'd noticed for some of these games that-- at least on the site I usually DL my ROMS from-- some of them had rather large CHD files there too to DL. In fact, Capcom Vs SNK Mark of the Millennium (cvs2gd.zip for MAME) had one, but I didn't actually DL the CHD-- hell, I'm still not sure of what these are, and where to file them-- but it seemed to work OK. How essential are these files?
-
For Sega Strike Fighter (sstrkfgt.zip for MAME), it loaded to the NAOMI logo, but gave me a warning like "Game Assignments are Incorrect. Set Correctly In System Assignments of Test Mode." I have another ROM for this labeled (Rev A)(Mame 0.150, should I try that one instead? Or how/where would I adjust those Assignments if it's not a matter of the ROM itself?
-
Street Fighter Zero 3 Upper (the Japan version, sfz3ugd.zip, which was actually the only one included on this site besides the GBA version) also didn't load/again stopped at the NAOMI logo, with a warning "Error 01: This Game is Not Acceptable By Main Board." There was also a CHD file for this one that I didn't know what to do with. Could that be the reason why?
Thanks!!

Best practice is ... If it has a CHD file, then use it.
If the game does not run, then most likely the reason is it needs the CHD.
create a folder named sfz3ugd and then unzip the contents of sfz3ugd-chd.zip into it. (the file inside the folder should be called gdl-0002.chd)
then transfer both into the naomi roms folder
sfz3ugd.zip (which is game)
sfz3ugd (which is the folder containing gdl-0002.chd)
restart emulationstation and you're done.
Note: games with CHD file take a little longer to start, so be patient.
PS. I tested the game with lr-flycast ... works and runs great :)

sfz3ugd
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:

So, anyone got any ideas? :/

In the same folder as the zip you need to create a folder called "sfz3ugd" and place the chd file there.
Also ensure you're running the game from the zip and not the CHD -
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.
