Nice games. Wish I would have found those back in the day but no such luck.

Back in the 90's, NES clones were all the rage in Eastern Europe:

With ludicrous names like "Gold Leopard King" https://www.reddit.com/r/crappyoffbrands/comments/1ekwzx5/go...

Or mimicking a Sega Genesis package and console look, this is the one that was most popular in Romania and I had one too : https://gadget.ro/wp-content/uploads/2014/04/terminator2.jpg

There's still a ton of old cartridges for it on sale on the flea market: https://www.olx.ro/d/oferta/jocuri-clona-nes-dischete-casete...

Back in the 90's, buying such a cartridge was a big decision, since a single one would cost the allowance for several months. And with no Internet and YouTube to run a search for "Haunted Haloween 85 NES", the only criteria for evaluating such a game in the physical flea market was the poster on the cartridge. Which, unlike the OPs which at least seem to pose a resemblance to the actual game, it had almost nothing to do with how the game will look.

Consequently I almost never got the good games and was utter disappointed after trying them. Fortunately there were neighbors who also bought and we exchanged cartridges, and so I found the best game I ever remember playing on such a console, Mighty Final Fight: https://www.youtube.com/watch?v=hoUPvwCcUo8
