Sega Naomi in lr-reicast

MrLightgun

There is some great advice for this too in the working dreamcast games thread also:

https://retropie.org.uk/forum/topic/21031/working-dreamcast-games

If you get failures when loading all roms in lr-Reciast then there is a useful script fix suggested in the above thread.

I think it's incredible these games work on the Raspberry Pi.

I was able to get the following working with Lightgun:

House Of The Dead 2
Confidential Mission
Maze Of Kings

However House Of The Dead 2 has quite a lot of graphical glitches so it will be better getting the Lightgun working on the Dreamcast version which runs better.

I manage to improve the performance a little bit since this video but not as much on this system as with some others.

Thanks for the guide!

This works perfectly on the RPi4.
Just took me some time to find all the BIOS with the correct checksum (available in the wiki for anyone who wonders).
I did not have the monkey ball reverse analog by default so that is either fixed or non-existing on my specific setup.

Does naomi have a separate directory by default or do I need to create a custom colection?

In RetroPie, no - it uses the dreamcast folder.

I fixed it last year.

To ensure that your .ZIPs will work, you can match the contents of a given game's .ZIP with it's entry in this file.

So if my game is not listed in that header, then it is not supported, Is this correct?

Edit: I was specifically thinking of Tokyo Bus Tour, but I just noticed that one might be available as a regular Dreamcast rom.

Hi there,
i am trying to boot fist of north star with recalbox.
In your opinion, there May be a Way to make this work?

@asici2

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

langest

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?

RetroPie Version 4.5.14 (f541deb) (current master)

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.

mitu

@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?

zerojay

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.
