If so, could there be some kind of flag or indication it is not an official version perhaps ?
Practical example of this: Let's take a quick glance at The Hobbit , I want to mention I only grabbed this as I knew a little about it generally.
The listing states the following:
That's quite true however as they do exist but the concern here is the +4 version is not an official one, its been 'enthusiast built' from the C64 version. Nothing wrong with that, the conversion itself is actually excellent anyway. All AFAIK.Other platforms: Amstrad CPC , BBC Micro, Commodore 64 , Commodore Plus/4 , MSX
As a sidenote to this there's also an OricAtmos (48K machine not 16K) version of the above title too. I have it.
With the above in mind, what is the official take on this please ? I do want to add that I'm not actually fussy either way on it and can see various practicalities with marking down versions as being 'official' or not, not to mention the time taken to actually find out about them in the first place.
Also a few years back I did a few ports to the BBC Micro of a handful of Speccy games too (yes really) so I am not sure if you would like specifics on these to consider their "Other platforms:" status. One of them I even managed to get ahold of and get a positive response from the original author and obtain permission! The others ignored me.
