If you are a lover of the most classic console games such as the Game Boy Advance, Super Nintendo, Mega Drive and others, you are going to hallucinate what we bring you today. You may have already played one of these consoles using downloaded emulators on your PC, but what if you didn't need to install anything to play? Today we bring you a compilation of the best online emulators to play retro games from the browser.
Emulators + ROMs, how do they work?

If this is the first time you hear about emulators or ROMs, the first thing is that you know what they are about and what are the key points of this system to play games. We could say that, to carry out this process, we have two different parts:
- emulator or kernel: The first member of this equation is in charge, as its own name indicates, of acting as the console. It is an "app" that will emulate any old game console you can imagine such as the SNES, Amstrad, Neo Geo Pocket, Spectrum and many more. Some are endowed with certain advantages such as autosave, stability improvements, speed and many other details.
- ROMs or games: this second part is easy to understand. ROMs are the games themselves in a compatible extension that allows emulators to play them and start playing.
So, in order to play any title that you played (or wanted to play) in your childhood, you will need to find both elements, that is, the game and the emulator of the corresponding console.
For our part, we cannot instruct or encourage you to use the ROMs. But it is completely legal for us to talk to you about emulators and where to find them and, for the rest, it will depend on what each user wants to do under their own responsibility. But, as you already know, the internet is very wise and surely has a solution for this.
Online emulators: the most comfortable system
However, although the most common way was to look for both pieces, currently there are many options for web which, in your code, include the emulator itself.
Therefore, the only thing that we would have to do is own the ROM in question that we want to play, load it / upload it to the web and start playing. Or, there are even websites that directly include classic games within their code. Although of course, these may stop working in the future if they do not legalize and pay all the necessary rights.
That being said, here is a list classified by consoles of the different emulators available and the ROM extensions with which they are compatible. And, in the case of incorporating the games, we will also indicate it to you.
Nintendo Entertainment System NES

The best websites with an emulator that allows us to play titles of NES are:
- NESBOX: It is an emulator that will link directly (as a directory for the games) with our Onedrive account.
- tripletsandus: here the games are already included in the page itself. We will only have to search for our favorite titles and click on “Play Now”.
- 8BBIT: same as above. A list of titles with a search engine among which you can locate and play NES games simply by clicking on them.
