Building a new Sega Neptune in 2024! Let's bring a canceled console back to life!

Thanks to PCBway for sponsoring this video! www.pcbway.com/ The Sega Neptune was a combined Sega Genesis/32x console that was canceled before it was released. Very few prototypes of the Sega Neptune were made, but thanks to modern 3d printing and the retro community, we can now build our own Sega Neptune! In this week's Fix it Friday, we will walk you through all the steps to build this console. Special thanks to Flashback Gaming ( / flashbackgaming1 ) and PCBway for their help with this project!

Oh no totally not fake, I saw Titos (Aka macho nacho) show on this Edit: aaaaaaand ironically both shows hard coded pcb way into the video 😂

I would buy one of those pre-built in a heartbeat as I remember seeing them in magazines but was bummed it got canceled. Nice work.

[@user-ff6pq1eg8x]

Hope someone builds an Atari Panther or an Atari Jaguar II which they themselves were cancelled systems.

[@GreyMatterShades]

The Neptune mod looks awesome, great job! I guess the next step would be for someone to design a case and mod for the Neptune build to fit in with a Sega CD (probably version 1?), for an all enclosed, single power sourced tower of power. I'd love to see that!

The next step would be to create a new donar pcb with the boards combined to transfer the ics to. The power circuits and video circuits could be merged somewhat saving space, a daughter board could be created if more space needed.

[@kameleongreen]

I've seen people do this mod a handful of times and i've always wondered why nobody has designed a new board to house all the components from the genesis and the 32x (plus whatever mods) so that you can just add the major donor components from the old systems, and just replace caps and stuff with new. It looks like just a 2 layer board, and im sure there are schematics online somewhere. Yeah, I know the soldering would be difficult though... one can dream!

[@rustymixer2886]

Fun fact, Sega had 5 to 6 32 bit systems 32x, Saturn, Jupiter, Pluto and Titan (Arcade) plus this planned Neptune...and that was the beginning of end 65% market share 1994 to 2001 0% !

[@LennyMill]

Jupiter and Pluto were never released either

[@rustymixer2886]

@LennyMill Pluto prototypes were made though

[@MarkThePulverizer]

​@@rustymixer2886no prototypes were ever made of the Jupiter as it was scrapped very early on. It was essentially The Saturn but it ran on cartridges. And the idea was they could sell a cd drive separately. But they went cd only instead. The Pluto was just a cost revised Saturn like the model 2 Megadrive was to the model 1. So they weren't different 32 bit systems they were just the Saturn.

I have been fixing game console for over 25 years.. I have plenty of skills. Do you know how much a 32x cost nowadays. They are not cheap compared to a Genesis Model 2. I can defiantly build one of these.. I am saying it would be kewl if Sega would release a mini version of it. I am a huge Sega Fan. I own many Sega Consoles. I don't want to tear down my stock 32X that I bought when it came out. If you are a Sega Fan/Collector you would understand this@@lucasrem

So krikzz the maker of everdrives has been working on a 32x cartridge adapter. Just plug and play. I'm going to wait for that to come out to do this mod. That way I don't have to cannibalize a 32x. But I do love this project overall.

[@hammerheadms]

Yeah, I gotta perform this mod for my 32X.

[@jsonic1045]

I forget if I mentioned this on Macho's video, but I recall a time when I was younger, finding out that 32X didn't play nice with Sonic & Knuckles lock-on. I had rented two copies of Sonic 3 and returned them, under the impression that something was wrong with them, because the game wouldn't run properly when loaded on top of Sonic & Knuckles which itself was loaded on top of the 32X. I think it would be an interesting little video if the Sega Neptune mod runs into this same issue or not. Maybe figuring out why.

[@dennj]

i recall this issue as well, if memory serves when you put sonic 3 on top of sonic and knuckles, you will just get the no way screen when doing this through the 32x. it been so long ago but i believe i ran into this problem as a kid as well

[@SilentNill]

Amazing 🎉

[@kirikinolatx]

I did also mess up with the LED bit when I ordered! Just because Tito did not mention it has to be transparent... so I had to reorder, hopefully that solves the issue when I receive it!

[@blueskies792]

[@dethfactor]

Hmm... I just got done installing / recapping my 1VA6 Genesis and adding Zaxour's 3BP to it. Wondering if the stock case has enough clearance to piggyback a 32x in there.. Also since I'm using his Genesis 2 Din with the 3BP piggybacked on its possible to use the little DIN boards to piggyback on top the 3BP or it needs to passthrough the 32x. I'm not to privvy to how the 32x outputs things but a V1 Trojan 32x might be neat if doable.

[@edoardolunghi3385]

Superlative!

[@Clancydaenlightened]

Now add a Sega cd and either run a custom scd bios that allows 32x co support Or allow 32x to load in custom bios And just throw 2 epm570t and a esp32 With a few megs of sram and a nor/nand flash on a 32x cartridge Now you get 32x support and acceleration but wit dat cd loading and extra coprocessing from sega cd With sprite manipulation, and 3d render from 32x, with the sega Genesis cpu just doing the basic bus and io management

[@youkai05]

That looks really sweet!!! How did you do the decal? Is it waterslide?

What type of resin was selected on the PCBWay website?

[@retrobear9367]

id like to see someone create some sort of adapter that allows the 32x work on the Nomad. My Nomad is triple bypassed. Either that, or make an Everdrive that doesn't require the 32x hardware to run roms. OH! Question. My Nomad has an TFT upgrade. Would it be possible to upgrade it further to the rgb lcd?

[@LIRetroGaming]

Yes, it’s totally possible to remove the tft on your nomad and replace it with an LCDDRV. I did that to mine and it’s a big improvement!

This is so cool. I hate the ribbon cables in the 32X as I can't find any replacements for mine that I kinda mangled. If I had an extra 32X I'd def try to make my own neptune.

-You can make those cables up. Just buy a larger one and trim it. I've been doing flex cables replacements and extensions like that since I can remember for Ps2 specially, Saturn DReamcast, PSx, Ps3, Ps4 and Xbox disc drives use the same kind... etc. Just grab an exacto, a rule, a multimeter for continuity checking and some patience, and you can make any of those white flexes: if you have the right type just trim it. it doesn't matter the number of traces. You can deal with that, and remember to add the blue plastic, though it it's replaceable too. Just be resourceful when and while you can. Cheers!
