Yeah I know how to make the cable. I was just wondering will a Dreamcast extension cable work instead of me ruining one of my good working DC controllers is what im saying. Because I tried to make a RJ-45 USB cable with a USB extension cord one time and It didn’t work. Which is why I wanna know if anyone has tried already before I buy.
There also pre-made Dreamcast RJ45 cables on the market.
Paradise Arcade and Focus Attack sells them.
Yeah, But I already have the material and equipment to make my own. Plus its like a million times cheaper to make one than to buy a premade one LOL!
Whats cheaper? Buying premade or ruining several existing Dreamcast cables to mod them with RJ45 connectors? Factor in your time, fustration, used up RJ45 connectors, the RJ45 crimped and any other materials.
That’s why Im trying to get some information from people if an extension cable is doable so I DON’T have to ruin a perfectly good working controller.
Bro, I can make any RJ-45 cable in like, less than 30 seconds…minimum. A premade RJ-45 to DC connector from focusattack is 13 dollars PLUS shipping. The extension cable Im trying to acquire information on only cost 5 dollars SHIPPED. I’m sure you’re smart enough to do the math and understand my method is the one that makes the most sense ROFL!
Anyway. I came here for information. Not to argue. If you cannot help me than by all means sir, have a nice day.
EDIT: rtdzign came thru and gave me all the answers I was looking for. I no longer need any help on this matter.
Dude you are the one arguing, I pointed you out to rtdzign’s first post in this very thread dealing with DC cables. And when you didn’t like that answer I provided you with other options.
If rtdzign already posted about something 4 years ago in a stickied thread, its going to work.

Curiously checking to see if it’s possible to make a db15 rj45 cable and if the the mc Cthulhu will support it. If so, what’s the pin out?

Having the same issue… anyone get past this?
For me PCE support has always been hit or miss. I chalk it up to there being about a dozen variants of the system and the way it behaves when you have a multitap plugged in.
I’ll be picking one up and will let you know what’s happening.
Behavior with the tap is the same 
I’ll be getting a Turbo Everdrive later this week so I can test with some US games as some people have stated that only JP HU Card games exhibit this issue.
Just got My turbo Everdrive, Tested a bunch of JP games and they work perfectly, even R-Type. Looks like the issue is only with JP HuCards 
Quick question for any who have successfully done this mod before. I just tried it myself over the weekend and am being met with bad/no results. Soldered a cat-5 cable to the Cthulhu with no mishaps, board isn’t fried or anything since I can still get the stick to play just fine with I hook it up to anything through the standard, on-board USB jack. I don’t have too much soldering experience, so this is the first thing I checked when finishing the mod.
After that I wanted to test out the ethernet jack itself, so I made two cables using the instructions here on the board: USB and PS2. I found the PS2 one somewhat difficult to make, so when I tried it on my PS2 and it didn’t work I wasn’t too surprised. I made the USB one next much more easily, but it still didn’t work on my PC or PS3.
So I can see two pretty obvious points of failure:
- My soldering of the CAT-5 cable to the PCB wasn’t great, so I’m not getting continuity somewhere in there.
- I botched both of those cables that I made.
I don’t have a lot of experience soldering or crimping cables, so either one is likely. However I feel like I’d like to rule out the soldering part first. I’m pretty new to electronics repair in general, but I definitely have the tools. So I’m going ask what is probably a really basic, dumb question: How exactly do I use my multimeter to check my soldering job and make sure I’m getting continuity? I definitely did my research before asking this here, but maybe I wasn’t searching for the right things. If someone could even point me to some online tutorial for a similar application to what I’ve talked about here, that would be just fine.
Thanks!
I just picked up a multimeter myself and am also wondering what setting/mode i need to have it on to test continuity. for instance, when showing the picture with the ps2 controller and all the colors to match the numbers, what’s going to show up on the multimeter that lets me know what wire goes where?
Is there a place that sells an RJ-45-ready McCthulhu (e.g., w/ an Ethernet port), with wire terminals (i.e., no soldering required to connect the wires)? Soldering and crimping is really out of my world… 
No, but sometimes a soldered one pops up in the trading outlet.
Anyone ever tried making a universal cable with interchangeable connector heads? Seems like most people just make sets of individual RJ-45 cables for each of their consoles, but it’d be nice to have one detachable cable for the arcade stick, with hot-swappable plugs/connector heads for the console ends.
I really like the Xbox 360 breakaway cable implementation, would love something similar for MC sticks where the breakaway end could double as both a trip guard and a hot-swap system for PSX, Dreamcast, OG Xbox, Gamecube, etc. terminals.
I’m not sure how many physical pins the 360 breakaway cable supports, if only the 4 standard USB pins then I’m guessing 360 cables couldn’t be hacked to work with older cables that use up to 7 pins like the PSX. But maybe there are breakaway mini-DIN 8 (or other) solutions that function similarly that could be used? Or are there any unnecessary pins on a PSX cable that can be left out to work with an OG Xbox/360 breakaway cable (OG Xbox supports up to 5 pins, 360 I believe 4 from looking at mine)? I think the Gamecube only has 3 necessary pins and the extras can be forgone to lose features like rumble, can something similar be done with PSX?
Obviously you could do this with something like a female to female RJ-45 adapter but that would be a really ugly and clumsy solution. It would probably only be worth doing with something more elegant like the OG Xbox/360 breakaway system.
I couldn’t find anything via search, not sure if this has already been done/discussed before.
EDIT: I found an old Radioshack PS2 breakaway extension cable, obviously with these being in short supply and $20+ each you definitely wouldn’t be hacking them, but surely we can find something similar that would work.
It’d actually be really nice if we could source a manufacturer that could produce both the terminal ends and the breakaway cables themselves so we could have something that looks professional and stock, using uniform colored shieldings and plug terminals. If we just bought the breakaway mouldings/connectors in bulk we’d have to use some type of heatshrink or sleeving, and all the plugs and wire shieldings would be in random colors. Be nice to shorten up the barrels to the breakaway plugs a bit too for something a little more compact, even the stock Xbox 360 breakaway units run a tad long at ~2.5" total, in my opinion.
