Sega Retro:Todo/Magazine check

Crude but workable way of determining how magazines are being referenced on Sega Retro.

It takes a while to compute:

{{MagCheck|code=smf}}

Sega Master Force (UK) #1: "August 1993" (1993-06-24):

Sega Master Force (UK) #2: "September 1993" (1993-07-22):

Sega Master Force (UK) #3: "October 1993" (1993-08-19):

Sega Master Force (UK) #4: "Autumn 1993" (1993-09-16):

Sega Master Force (UK) #5: "November 1993" (1993-10-14):

Sega Master Force (UK) #6: "December 1993" (1993-11-11):

You can also specify a single issue:

{{MagCheck|code=mdag|issue=1}}

Sega Mega Drive Advanced Gaming (UK) #1: "September 1992" (1992-xx-xx):

The "gaps" are filled by any template that calls Template:MagStore: magazine article rows and print advert galleries. The idea is to fill in the empty squares.

Things it probably isn't handling properly:

• multi-page reviews
• reprints
• pages that cover multiple topics - e.g. if there's an advert for three games, it'll just show the one
• you'll get the occasional red square because it gets confused with some punctuation. The issue is fixed, but it might take some time for the wiki to update.
