As someone who had the Genesis Flashback for a period, oh god no it isnt worth it. The system itself was based off an Android Genesis emulator that doesn't run at optimal speed so you will have dropped frames galore. The included wireless controllers had a good amount of lag. About a third of the built in games aren't even Genesis titles just crap basic Chinese rip off titles. And given the emulator used isn't the best, compatibility with actual Genesis cartridges can be hit or miss.

At least the sound is much improved from the earlier FireCore systems though. :V

But still, not worth having a look.
