I had tried that, but do you have any idea how the input for that works on Naomi?

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.

@barbudreadmon I can confirm that Samurai Shodown VI is bad, and I've seen no difference in performance even after overclocking. I tried playing it yesterday and it was like playing Samurai Shodown under water. Not fun.

barbudreadmon

@Zering You can probably improve playability by increasing frameskip, it won't be a smooth experience though

Zering

@barbudreadmon I'm pretty sure frameskip was on when I tried it. It just feels broken.
Having said that I'm still in awe at flycast's performance, it's the only game I could find that did not work properly.

Okay, thanks for the tip! I guess if it is running poorly anyway, I won't bother (although I say that, and curiousity will get better of me and I will try it).

Are there any other good Atomiswave fighters apart from Guilty Gear?

Thanks on the lr-reicast point, I was confused.

Edit: The nvmem deletion worked! Superb tip. They were in the roms/Atomiswave folder, for the record.

Zering

@AdamBeGood Have you tried King of Fighters?

King of Fighters XI? I have it to try but haven't given it a real go yet.

I just tried changing Alpha Sorting to Per Strip and I think Samurai Shodown is playable.... Sorry please have a look and tell me if I'm wrong, I'm not very familiar with the game.

Zering

@AdamBeGood I was on the fastest setting (whichever one that is) and it ran slowly.

King of Fighters XI is pretty good I think, let me know what you think.

Cool, I'll have a look. Used to love the Anime!

Specifically for Atomiswave, The Rumble Fish 1 and 2.

Thank you! I'll check them out.

Metal Slug 6 goes a bit mad on the first big boss.

Is there any way of getting round this? It seems to happen every time with Metal Slug 6. Thanks!

Zering

@AdamBeGood I think it happens every time with every ROM.

Also I've never played a single game of Metal Slug on any platform that didn't have some slowdown in some form or other ^^

Hahaha I am aware of that being a feature but this is beyond the usual lag!

Zering

@AdamBeGood Is your pi overclocked?
I did not see any slowdown while playing Atomiswave, but then again I did not play for very long.
Also there are options in lr-flycast that improve performance.

If you overclock the emulator cpu (not to be confused with overclocking the pi) to 200

Then the slowdown in the early Metal Slug games is gone.

Remember, the original games had slowdown in the arcade ... if you're a purist, then leave the emulator at the default cpu setting, if you want the slowdown gone, then overclock it.

Grab the Sony PSP version of Metal Slug anthology ... Metal Slug 6 plays perfectly, no slowdown particularity on the 1st Boss which the lr-flycast struggles with.

Example: the boss below suffers no slowdown in the PSP version but does using the naomi version using lr-flycast
