Recently I have been wondering where the "Emo Demo" game by Sintax came from. I know it is a demo for their Castlevania clone, but I don't remember ever seeing any demo carts for any Bootleg/Unlicensed games. That got me thinking that a thread for asking where some of these old pirate game ROMs came from could be a fun idea. I decided to put this in Pirate talk since there are probably a lot of games that people do not know the origin of for consoles that are not Gameboys.
Note: Yes, I am aware that Taizou once mentioned that the demo likely was made to show off to potential business partners. I am just using it as an example because much of its origin is still pretty mysterious (like whether or not a cart of it exists, what the cart looks like if it does exist, and whether or not more Sintax demo games exist)
