Sega Naomi in lr-reicast

this is not recalbox forum
as long as you are using lr-flycast & proper romset/bios, this game is supported

I updated lr-flycast from source and this broke my working naomi games.
Did this happen to someone else at some point?
Any idea if some changes to flycast has been made that might break old naomi setups?

Is there a way to play Naomi arcade games on Mame in Retropie? Thinking Mame2016 might be a viable core to try? I have BIOS files, not sure where to place them.

@GreenHawk84 no, flycast is your only option

I am having trouble with games with .CHD files. All NAOMI and Atomiswave games that are just .ZIPs have been fine.

I'm trying to play Monkey Ball and Ikaragu but both of them give me "Error 01 This game is not acceptable by the main board".

Any idea why this is? I've tried putting the CHDs within folders of the same name in the Dreamcast folder, ie. Dreamcast/ikaragua and I've tried with the CHDs in the Dreamcast folder also.

@AdamBeGood Can you add more details - what are the rom/folders/chd names you've tried ? For instance, the file structure for Monkey Ball should be:

monkeyba.zip
monkeyba/gds-0008.chd

Another thing to check if you have the required BIOS files - maybe you're missing the Naomi GDrom BIOS (naomigd.zip ?).

No, naomigd.zip isn't required by flycast.

@mitu Thanks for the advice, I have Monkey Ball working now! Ikaragu is still a problem but I have it on Switch and XBox so I'm not going to lose sleep over that.

Maybe because you're spelling it wrong...

AdamBeGood

@mitu I did get it working after the event, I started again with it, after deleting my initial attempt. So it isn't impossible that is the reason... I really hope not though.

If anyone has any good Naomi or Atomiswave recommendations, I'd be interested.

Dolphin Blue is pretty awesome for Atomiswave if you like Metal Slug run and gun type games.

@ReadyPlayaWon Giving it a play now! Love it!

Has anyone tried out Tokyo Bus Guide? I always get the error "Motor Network Error In:f0 Out: ff", presumably because there is no pedal apparatus or something like that. Is there any way of getting rid of the error message?

I think 18 Wheeler also has that error or something similar come up but it doesn't stop the game from playing. I don't know of a fix as I'm pretty certain that's a motor or servo that it's trying to control and it cannot be found.

The 1st place i would look is in the Service Mode of the Arcade Rom.

That's usually where the internal hardware setup of the original arcade roms is.

eg. steering wheel calibration, slave/master cabinet settings etc can be configured.

I had tried that, but do you have any idea how the input for that works on Naomi? I've plugged a keyboard in and still I can't seem to navigate. Pressing Start on the Controller when the Naomi menu is displayed seems to bring the menu up but I can't really access it.

The screen says "Select with service button and press test button", but all I can do is press Start on Exit, so far as I can tell.

Firstly, you have to enable Service mode in the lr-reicast/lr-flycast emulator

under Options > Allow NAOMI Service Buttons > On

then map the Service and Test buttons to your controller

Controls > Port 1 Controls

Yep, that worked! I can't seem to find the option to disable the motor and get rid of the message, but I can live with it. Thank you!

Same error is listed here under 18-Wheeler so it looks like this might just be something that isn't fixed as yet: https://github.com/mamedev/mame/blob/master/src/mame/drivers/naomi.cpp

Is the bottom "input" line below relevant at all? I've had a few ROMs fail when that line is included. Does anything need to be done to make these games work?

Edit: I just get a Sammy splash screen, then a totally grey screen, and then a colourful horizontal bar appears across that screen about two thirds of the way down. Has anyone got this game to work?

Although I am using Flycast, let me try reicast.

Further Edit: I can't even see lr-reicast as an option... I have "reicast-audio-alsa" installed. That doesn't work.

Delete your eeproms for this game, they should be named samsptk.zip.nvmem and samsptk.zip.nvmem2, and located wherever your savefiles are supposed to be (i think retropie is storing them in a subfolder of the rom folder), that shit happens from time to time when booting atomiswave games for the first time.
Also, i heard the pi4 gpu is notoriously bad at emulating samsho 6 (while other sbc like odroid n2 have no issues running it at fullspeed with upscaling).

lr-reicast doesn't exist, it was renamed lr-flycast a long time ago.
