How to Emulate Sega Genesis Games
To use a Sega Genesis emulator, you will need to download and install the emulator software on your computer (or in this case external USB flash drive). Once you have installed the emulator, you will need to download the game ROMs (which are digital copies of the original game) from a trusted source.
It's important to note that while emulators themselves are legal, downloading copyrighted game ROMs is not. Only download Sega ROMs for games that you own or have purchased the rights to use. Once you have downloaded a few game ROMs, you load them into the emulator and start playing.
It's also worth noting that some games may not work perfectly on Gens, so you may need to experiment with different emulators to find one that works best for the games you want to play.
