Do you mean just the insert? The way these are printed at the factory is offset print process which is very expensive and only works for runs in the tens of thousands, however I can probably get close using a film in my inkjet printer although it's quite reflective. It wouldn't cost £20 for one print

A laser print doesn't look quite right either as it produces a weird sheen and you basically get what CEX does with their shitty replacement inlays.
My Epson is brand new, it's more down to how you handle the digital process than the printer really, but it does matter. I have just bought an absolute gooseberry fool tonne of Epson papers including semi gloss and gloss papers.
I could do one on a range of papers and just choose your preference. I'm afraid the colours are never going to be exact because the factory prints are set up using a very specific colour calibration workflow and they may also use spot colours probably something called Pantone inks (Pantone matching system or PMS) which is not possible for one print (I can't do it anyway but I can print a CMYK that is close as I have the correct values for this). For example the Nintendo red is almost certainly a Pantone spot colour.
I do however have coated FOGRA certified proofing paper which while matte, should produce accurate colours if the colour profile is correct (it probably isn't).
If the artwork you want to print isn't 300-1200dpi I can't magic the detail into there but I can use an deep learning based resampling algorithm to make it look sharp without pixelation. Just find the highest resolution file you can and I'll print it off for you for whatever you are happy to pay plus 60p or whatever for a hard backed card envelope.
The markings you refer to are crop markings. It's literally my job for 5 years to slice material so that is no problem at all. I do it by hand using a scalpel and straight edge. If I wasn't good at that I'd have given up a very long time ago. If it was a larger run I'd do it by machine but there's no point for just a square.
I suggest you buy the instant download copy and I will manage the print and cut as accurately as possible.
