Atomiswave on the Sega Dreamcast without modification for just $9. Serial port SD card adapter. 

Just an update to mention that megavolt85 was able to modify metal slug 6 to work from the serial port and it runs much better than the CD version of the game. Link has been updated in the description.

This is almost too good to be true! I bought one of those cheap serial port kits from Ali Express a year or two ago, its been sitting in a drawer as I hadn’t a clue how to even approach using it, but happy RU-vid algorithm brought your vid to me! This is def a “must have” for any DC fan, thank you Sir and all of the folks that worked on this, truly a service for all in the DC fan community!

My Dreamcast has a serial port??? After 20 years you learn something new.

It blew my mind how easy you made this. Was kinda confused by the difficulty of getting Dreamshell to work with an SD adapter. It seems a lot of the projects in the past to get these games optimised/working have been put away with the recent popularity of GDEMU and MODE (and shutdown of romsites), This was a godsend, thank you!

you are the man! especially for reuploading metal slug 6 fixed! thank you for sharing this tutorial for those of us trying to get use out of the sd adapter, had no idea about retro dreams! 🙏

I just received the sd adapter from your link and everything is working flawlessly. Thank's for this video and the files.

Thanks Cris for you posting the link with out you alot of people would not know what to do bravo Cris👏👏

Bro...thanks for this. SAVED ME HOURS. got a janky SD reader on EBAY. Well it didn't work with straight ATOMISWAVE downloads. Your distro worked perfect.

I hope RU-vid removes the dislike button from this page, your solution hella worked. I didn’t think I’d get aromiswave games working. Every dc game I play works, but I didn’t get atomiswave until recently. Thank you so much 🙏

Thank you very much for your link just bought my SD adapter from a site and with out your link don't know we're to start thanks

I’ve just installed a gdemu and these games run perfectly.

underrrated video my guy! thanks for sharing 😄

Hello, many thanks for this. I only have issues with RD, it doesn't boot. and I had to update the IsoLoader to 6.6 otherwise I get a screen full of errors. Can you explain how to boot RD?

Dreamcast Best console hands down! Thanks for the info

Great video! I didn't know this serial adaptor was a thing.

You've explained this all so clearly and simply - thanks so much! To confirm, there is either no slowdown or minimal slowdown when using this method to play the Atomiswave titles? :)

Just bought one of these after watching your video, this thing is worth it for the Atomiswave games alone. Real Atomiswave arcade hardware and its games has gone up in price tremendously, especially Dolphin Blue which is arguably the systems best game. This will definitely help me get my Atomiswave fix for sure. Quick question though, have the issues with some of the Atomiswave games running through the serial port been rectified since posting this video?

Whats the best solution in 2023 to have dreamcast running all dreamcast games? GDemu ?

The Aliexpress seller never shipped out so I had to cancel and get issued a refund, I decided to go with a seller on eBay who was selling SD card adapters already (albeit no CD-R, given instructions said to burn it yourself). So I tried burning that boot disc image you provided with Nero Burning ROM at the slowest speed, since it was in NRG instead of the usual CDI for DiscJugglar. Just kicks me back to the menu, I decided to just to use a disc of DreamShell RC5 while updating the folder you provided on the Dreamcast-Talk forum post to an earlier version that was closest compatible since trying the boot disc for RC4 stalled at the Dreamcast logo. Feels like later versions are more dedicated for the modded IDE HDD solution, to which I strictly want to play Atomiswave through this SD card adapter as a strictly softmod solution.

I wish they could do this to be able to play Naomi games and regular dc games (kind of like gdemu without having to open up the console)

Broooooo! This is valuable information. Fair play to ya

Man this is epic

Hey You really did a great job on this video! So informative and helpful. I did have one question though, is there a way to go back to the retrodream menu from ingame? Ive tried holding down a+b+y+x+start but it doesnt seem to work. Not sure if there is another way. Any hep would be greatly appreciated.

Any chance you can post the links without the hyperlink? RU-vid is being dumb with their redirects and the link breaks for me.

I did what he did and it is great. I even use the newly made Quake 3 Custom Map edition online and it works great. The only game I can't play is Dirty Pigskin Football.

Thanks for this. I have Fist of the North Star on my modded PS3 but it runs slow. I will use this method.

Thank you! Great video! What size SD card is needed to hold everything!

But there was a previous adapter that did the same thing hooking up to the serial port in the back of the Dreamcast where if you are going to play a more complex game that requires more speed there will be slow down issues or errors because the serial port is not made for that high of a data rate

Great video dude!

Hi. I copy all the files that you give to my 4g SD card but it wont work. When i put isoloader it make loading but some rgb error happen. I got a european dreamcast

My DC games are .gdi with .bin files, but the ones in your folder are .gdi with .iso and .raw files. Will they still work? Or should I use the same format in your example folders? Thanks for the video though!

i get stuck in the first menu showing boot from ram or boot from CD, i can use d-pad to select but no button selects the option. EDIT: Solution, i had to format the microSD card with 2 options in my iMac, with fat32 and also with "Master Boot Record" instead of "GUID Partition table"

Thank you for this.

Thx...l a huge atomiswave fan...I owned a arcade board back in the day

I`m going to have to use this method I think. I`m having trouble with them on the GD-EMU.

Great video, just order my serial reader from the link in the description and I can’t wait to try this out, is there no metal slug 6?

Very interesting video and congratulations. What I still don't understand, every time I want to change the game, do I have to turn off the dremcast and restart it? Or is there a specific procedure? For now I am waiting for the micro usb stick to not read data before turning off the dremcast. There is an alternative way to quit the game and turn off the console. Or does it shut down smoothly and this does not lead to hardware problems?

It would be good if a sega model 2 and 3 device could be made for the Dreamcast

Dolphin blue when you get it from atomiswave does it come widescreen or regular

Hey Chris, thanks a lot for the fantastic job man! I got the individual games from the dreamcast-tak topic and managed to run them (except Knights of Valour and KenJou ofcourse) then i found this vid and your pack... long story short: I'm using a DreamShell_4.0.0_RC4 disc to boot, but with your pack it boots directly to the Dreamshell desktop and i can only play Kenjou via the icon. How can i get to the boot menu selection or boot directly into Retrodream to see the other games? Thanks in advance! DC forever!

What model Dreamcast does this work with? 0, 1, 2?

Cris why is it that extreme hunting doesn't work also what size memory cart do you recommend thanks

cool music btw

I forgot a curiosity, but the Atomiswave games, which run on Dremcast, are they emulated or they run as if it were original hardware? Thanks

thx man :3 work well :3

Cris why does fist of the north star look pixulated

So would this work for Crazy Taxi, Shenmmue, Hydro Thunder, or for the good games do I need to get a gdemu?

I’m noticing some sound stuttering in hokuto. The speed test seemed in line with the results other people have been getting. Have you noticed any sound stuttering in hokuto or other games?

I only discovered this mod today, I already have GDEMU setup in the Dreamcast so there is no optical drive, can I still do this mod? I already have Naomi and Atomiswave files in zip, do I just drop the zip files to the sd?

Can you tell us we're to add more games to your list.

Hi, do you play NeoGeo CD games on your Dreamcast? Is it possible to load some NeoGeo cd games on the sd card of DreamShell and run them on Dreamcast?

Hey Man, thanks for tutorial... but the link to boot disk it's down... please, were found the iso?... Thanks Bro!!!!

It would be handy if there was a list of compatible games for the SD reader. A lot of the games I tried either didn't have CD audio or they flat out ran terribly. Didn't get my money's worth when it came to utility although I do still enjoy having the device set up to use because it's just cool to be able to mess with consoles like that. Any suggestions game/app-wise to get my money's worth out of it?

hey.i just saw ur vid on here&im impressd.what site do i go to&download these?do i have to buy this thing or i can go into a walmart&buy what u had because i can buy the sd card at my walmart/can it be a memory stick?please gets back to me on this.what site can i go to so i can look at the games i can play?thanks again.

thanks! If i want to update Dreamshell with the lates DS folder, can i overwrite it on the DS folder in your pack? Does Dreamshell have a good compatibility using a microSD support and a Japanese Dreamcast? I read that it is not easy to create running imagest fro Dreamshell..:( Thank you

Is it normal for the adaptor to have a bunch of burn marks on it? It looks like they did a crap job of soldering it

Games will not launch I get a configuration error

have the 2 games been fixed now to work with dreamshell?

how to burn the disc file ? cuz the file is not an iso,pls help im using img burn

That seems awesome buddy, but for some reason I can't seem to be able to download the file. Is it something to do with the server? Has anyone else had the same issue? Thanks in advance and congrats on the fantastic work you've done!

Hi, what's the difference between this and dreamshell?

Is it support 64gb micro sd card ?

Cris can you add more games to your post thanks

my dc is broken, the dreamshell i can use it, Thanks

Most the games are loading to a black screen ?

Dude that boot image doesn't work! I used imgburn convert to iso and used Alcohol and even used Nero to burn it...NG. Also there is no sound on any of the games is that normal? I just used my Dreamshell disk

There a Lupin the 3rd game on there it's a rail Shooter. Surprise that wasn't on there?

They've been running dreamshell from the serial port in CD for several years it does have lots of flaws. Some cases it's better to have a working Dreamcast and then one that is modded because those CD drives suck anyways SD card device you're reviewing with dreamshell it does have issues we're doesn't play certain games or the transfer rate of data is too slow

the site Gofile doesn't have the files to put in the CD and it only said this *"This upload does not exist"*what can I do to get it?

no one has a loading time video :(

Does dolphin blue get past the 3rd stage yet?

It's just better to get the Gd emu and then have a second Dreamcast that plays the discs as the GD ROMs are very problematic

So this mod requires me to have a cd ? I was gonna try to burn my games but i read that the (j) Japanese dreamcast does not support that

I get a preset error ISO cannot be mounted.

Download the link ? which link ?

Where can I download these games?

The best Sega is the Master system .

I'd use this to finally get the Genesis emulator to run on it. Years ago I attempted to get it going on my Dreamcast via a CD image I was given, but it never booted.

But i believe the games run slower thats the difference

Yes but the games run slower

Some games drop frames using this method.
