is this a rom hack, or pokemon essentials?

Pokemon Essentials.

The link provided says your youtube has been terminated due to multiple or severe violations of YouTube's policies.

Whoopsie. Fixed now.

Is the game completed ?

The game is complete, yes.

It appears as if you have on-map enemies? That's interesting. I'll give it a look.

I have a problem with the game apparently it closes when I want to open it it tells me that the emulation has stopped and it closes immediately then I open it again and it tells me the same thing I do not know what it will be but I need help please

"Emulation" has stopped??
This isn't a rom.

Try decompressing the ZIP file and actually looking at what's inside.

Oh, just realized I have been playing the one from Twitter, which was version 1.02. You might want to update the links there. By the way, what are the differences between 1.02 and 1.10?
Got to say, I'm enjoying the game so far, love the tilesets as well as the minigame, it's pretty neat and fun! I haven't completed it yet, just got done with fighting Hasty and his Kyurem and something got me pretty curious about, is it possible to get Diancie anywhere? I'm a sucker for that Pokémon. :D

Main differences between 1.02 and 1.10 are some bugfixes. Nothing gamebreaking.
1.10 also nerfs a certain fight later on. The fight is still winnable if you want a challenge, but frustrating.
Diancie is not available in this chapter of the game, unfortunately. If you pass me your save file I could drop one into your PC for you, if you'd like.

Glad to hear you're enjoying it!

Okie dokie, just making sure. :3
I really appreciate that but don't worry about that, I prefer catching instead of being inserted in anyway. :D

You're welcome! <3

So, I'm pretty sure you're avoiding relic-castle and other communities because you blatantly ripped the maps from the Pokemon Infinity demo games. But, I hope you have fun lying to people going forward about how you made all of it, and didn't just recycle things you never got permission for using. ;3

Hey doofus, Pokemon Essentials is an open source platform. Maps and tilesets are inherently open source by association. Literally every Pokemon fangame is going to be "ripping things off" from Pokemon if you want to go all the way.

Not true. Those tilesets weren't made by pokemon itself. Some of them and the map orientation were custom made purposed for a single game project. You downright ripped the entire map structure from a demo game. Without the knowledge and/or permissions of the first developers.

You clearly assumed everything is open source, and nothing is done by people personally. I'm not the doofus here.

Its like you didn't even bother to look past what you needed.

It's not like I'm avoiding them. I am the one who must not be named. Try asking about me or my games on Relic Castle and see what happens.

I wonder why.

Ask and find out. Why make assumptions?

I got spoiled on the ending of Pokémon Infinity - it’s all just the coma dream of a kid in the “real” world - which utterly ruins it and makes me never want to play. So personally, I’m glad that I get to explore the same beautiful region, but in a much better-sounding game.

That's the spirit. It's not about who did it first, it's about who did it best.
Sorry to hear that Infinity screwed the pooch.
