The Binding Blade "Remake" is a Romhack that ports FE6 into the engine of FE8.

And it sucks.

I am not linking this Romhack in the video description as part of discouraging people from going there to leave nasty comments.

If you would like to find it regardless, it's called The Binding Blade "Remake" and is accessible on Fire Emblem Universe.

Please quarantine any criticisms about the Romhack within my comments section and kindly do not bring controversy to FEU. Thanks.
