StoneAge Gamer still sells them in their own BitBox packaging and Krikzz still sells them on his site, however, most of the color variants are StoneAge Gamer exclusive.
Would I be able to change the homebrew to the correct category and have it approved?
I added a new entry here https://vgcollect.com/item/270150 Hopefully this is okay as this is what I would be doing going forward
Yes you can change them away from Homebrew to Unofficial Release.
For your entry, the description is wrong. We do not make any entry for an item that can contain multiple different things. What you would have to do is make an entry for each variant. And in the description you do not mention the other versions. Also I do not see if the term "Deluxe Edition" is on the packaging. If it is on the packaging, then you should put it in box text. If it is not on the packaging then that term can be put into alt-name.
Entry examples (that use the following presumptions)
1. That Deluxe Edition is not printed on the box
2. That the "Base" term for the cartridge is either on the box or in the manual
3. Base not being a valid color option
Stone Age Gamer Everdrive GG (Horizon)
Stone Age Gamer Everdrive GG (X7 Black)
Need to know what "Base" means in context of a color. It would not appear that Base = Black, since X7 has both.
PS: The retailer name should be Stone Age Gamer (with the spaces)
