That may be so, but I'm thinking that with proper pins the 3d printed connector actually can work well. The construction of the pins is very important and using the wrong sort of material is going to cause the issues you're having. But if you search for something more suitable you may find an affordable and easy to purchase solution.
So I wouldn't give up on the idea so soon. Honestly using those component leads as pins for the connector is probably a terrible choice, but it was good enough for a very rough prototype. You need something else that is meant as a pin connector for anything beyond a very basic proof of concept. You could look at various connector pins, maybe some crimp type pins that you put into a housing might be adaptable to a 3D print.
One of the key goals being you want something that is very unlikely to damage the connector on the console. I feel pretty confident a solution can be found to make it work.

Weren't you using old capacitor or resistor leads as pins though? Using something more appropriate would solve that issue.

I'm not shocked that an unlicensed product would do such a thing. Especially the cloned versions.
The voltage divider might work but then you'd need a lot of them as you'd need one for each signal. Might make more sense to use a dedicated IC. But whatever works.

You might want to design a version that does do proper voltage level translation. Often things do work without shifting between 5v and 3.3v levels but it could be causing stress on internal components and if it's in a custom IC that's going to suck if it results in premature failure.
The 3D model looks cool. I suppose a 3D printed casing would follow. Then you've got your whole home made rom cart.

The serial data link is a nice idea. I think that PSIO supports a USB link though that could achieve something similar. I've not tried it out but it is an option for me.
I like the improvised EPROM programmer. I have some older Willem based ones that operate over the parallel port and require jumper settings. I'd really like to get a newer USB one someday.
Looking forward to seeing you put the connector and EPROM together. Then maybe the next step would be to design a PCB to go from the connector pins to a EPROM socket.

That's certainly a lot faster. With the small amount of development I've done I have always just built an ISO and loaded it up in an emulator for quick tests and then later used PS-IO for real hardware tests. I had thought about the serial cable option but I like being able to load data from CD. But it all depends on what sort of development you're doing.

Yeah, deforming pins/contacts in the console's connector is definitely not good.
Are you planning to just hookup a EPROM with a Action Replay or GameShark ROM? Or the NoCash BIOS?

Well hopefully you don't have any resistors burn up. =)
Looking forward to seeing an update when you get a ROM booting.

Be very careful not to short anything out! Seems like a very possible hazard with exposed metal everywhere. I hope you manage to get a ROM wired up successfully.

This is a pretty cool idea. 3D printing your own connector is a nice alternative if you can't source something suitable. Do you plan to design a PCB to use with it?
