I have such an adaptor like iamatrackman so if anyone is interested I will sell it for the right price.

What is your "right price"?

No, not like that. A ribbon cable would have to connect those two parts together. I thought one end would look like a cartridge as well, otherwise it may fall out and blow the SFG-01 module.

The ribbon cable is what those two connectors are for, KiCAD doesn't let you make two separate board designs, so I had do panelize them. I can add the cartridge mounting holes to put it in a proper shell, but that's gonna have to wait a bit since I'm leaving for work while typing this.

I don't know exactly what kind of ribbon cable, how to insert it, or how to prevent it from falling out.

1. Standard 50p IDC
2. they're keyed so they only go in one way
3. friction

You still haven't answered the most important question? How much will you charge me for this adaptor?

Shipping will be the biggest issue, but the cost of the adapter after parts and manufacturing (since I'll have to put them together myself) should be about US$15.That's only a VERY rough guess, remember I haven't even finished the boards yet, and then I have to buy the connectors and cables.

I asked you how much would be the TOTAL amount you would charge me. You still haven't answered this question, so I'm waiting.

Well then, that's gonna have to wait until the adapters are made and I can ship them since shipping cost changes by country. I've no idea where you're located, but I'm assuming you're somewhere in Europe which hikes the shipping cost up quite a bit, since shipping from the US to Europe isn't cheap. Keep in mind, you're asking how much it's going to cost for something that doesn't exist yet to get to you. Anything I can give you is an extremely rough out-of-my-ass estimate, and I don't want to give an unrealistically low or high amount. If this has come off as rude, I didn't mean it to, but considering I only started to design the adapter last night and it was initially only going to be a one-off for myself, I feel it's still WAY too early to assume the final costs.
If I had them in my hands, ready to ship tomorrow via FedEx, to get them to London or Berlin in a week would be about $86 US, $99 for Stockholm or Oslo, and $101 for Amsterdam, PLUS the $15 cost per adapter, just as examples. To put it simply, I don't know.

EDIT: Does this seem to meet all the requirements? Two boards, ribbon connectors, cart shell mounting holes, front/back markings for proper insertion.

15$ for an adapter sounds reasonable. Shipment via courier is way too expensive. Why don't you use USPS? That will reduce the shipment price to 15$ or a bit more.

Also please make the part that goes into the 60 pin slot higher, so that there's enough grip to remove it. Otherwise people will be removing it by pulling the cable and that would eventually break the adapter.

Could you please show the other side of the board?

The other side of the board isn't exciting at all since it's just straight connections (solder mask layer removed).

I'll see how much longer I can make the SFG board while still keeping in the 100x100mm manufacturing limit before a massive price hike.

EDIT: As it's panelized right now, I only have 3mm to extend it, so it seems like some reworking is in order

If you check a few service manuals for Yamaha computers, some of the first pins in the 60 pin slot are connected. At least one is connected to Video, one to Audio and one to GND (ground). If you want to make a proper adapter, you need to check whether any of the hardware that uses the 60 pin slots actually make use of those signals. The Video signal is not present in the 50 pin slot, but Audio and GND are there.

For example the Yamaha SFG module definitely has one of the first pins connected to a component on the board:

In addition, you need to make the tracks that supply power (+5v, +12v and -12v) thicker than others.

These are the schematics I referenced. None of the first 10 pins have any connection going to them in the SFG, the rest are 1:1 with the MSX slot.
