Hi Darksoft, Thanks for replying, I've since said goodbye to the rr machine. I still have some parts. I didn't manage to get it going in the end, pity, I would have liked to change the ram and see if it sorted it.

I had a similar issue with mine when I bought it, I had to take out the cpu and re-seat it. Working fine since and a few years have passed.

Fan adapter Dreamcast pico psu mounting bracket Thanks for doing that

Thanks, it's my favourite colour combination. The only way I know how to measure the cpu temp would be with a temp gun and lift the usb gdrom off completely and check the steel plate underneath, it wouldn't be the most accurate but might give an idea

Can you check cpu temps aswell? Here's how it turned out Many thanks :thumbup:

I think the biggest heat problem is caused by the 12volts that's no longer used by the gdrom. I can feel the front left top of the dreamcast getting hot after a while playing, there are several variations of fixes for this but I didn't bother as I was interested to see if it would lead to a...

The cooling fan is pretty much open to drawing air from the atmosphere with the gdrom removed instead of drawing it through the air intake vents at the back. It can only help to draw air in the way it was designed.

I have a 3d printer myself so I'd only need the file if that's ok. I was thinking about flipping the usb but the usb gdrom are so expensive I wasn't going to mess with it, besides that, I'm ok with the external hdd too.

I have the original USB gd emu where the USB port went out the back of the dreamcast. Would you have a STL file with the same 3d model with the USB port closed up? :)

I've been testing that with various times and again the results vary a bit, sometimes it improves and then I go to far with the delay and strange results happen such as the reset relay activation happens the naomi resets, black screen, no game loads, relay activates again and again blank screen...

I have and I got the same results

Ok, I tried with another sun power supply and the results are the same, sometimes boots more often than not it wont, second or third selection of the same game and it will boot

I thought so too but I used the same power supply that I'm using on the naomi 2 that works fine. I have a spare powersupply that I can test later on just to be sure :thumbup:

Both boards have 4.01 fw, same multibios and security chip. I've tried both fans separately and together with a double relay. I don't know if Sega was working on one.

Using the same relay I've used on the other naomi. I've also swapped netdimm/pi3/relay from a working setup and got the same random loading/not loading

When i turn on the Naomi 2 and select a game it loads fine, the issue arises when i go to load another game, I select it and the relay resets the Naomi, then i (more often than not) get blank screen and everything sits there, I can see the network output trying to do something and i wait but...

Yup exactly like Darksoft said. Problem for me is that it still doesn't solve my hard reset/load game issue. Naomi 2 resets correctly everytime with no net dimm connected With net dimm connected the Naomi 2 begins resetting with screen going blank and at this stage it stays black and pi3 network...

OK, this is resetting my Naomi 2 Tested with and without resistor. Does this look ok?

Wow, this is making progress. If I can get my hands on a resistor later I will test to ground. Also, the signal strength on the pi3 wifi is incredible so I'd say you might be safe enough putting it in the case without having to do anything to it. Huge thanks to all for getting involved with...

Just to be clear on the issue, I have a dual channel relay that interrupts the feedback (yellow wire) from both gpu's. When I select a game using piforce web, the relays switch, opening the feedback wires on both gpu's, the Naomi screen goes blank and randomly stays blank and randomly reboots...
