Castlevania II: Belmont's Revenge (Autoboot + Speed + Improved Controls) (Hack) GBC ROM

Takes the game from Konami Collection Vol. 4 and makes it a stand alone game. Also slightly increases running and jumping speed to make it less painful, thanks to a separate hack by Silver X.
Once you try this version you'll never want to go back to the original!

README:

I admit the naming is confusing, even to me (Spike). I uploaded them all as they were created by the author. I will put down here part of the readme that explains the hacks and I will do my best to  explain IN MY OPINION what each one does. I emulated all of them and tested them and I'm pretty sure I'm right. So here you go:

This is what the readme says about them:

This hack adjusts Christopher Belmont's control scheme to be more like Mega Man or Symphony of the Night.

1. Belmont can now turn around and stop in mid-air.
2. Belmont regains control during knockback.
3. (`vcancel` patches only!) When the jump button is released, Belmont immediately starts falling again; this allows the player to make smaller hops if desired.
4. (`inertia` patches only!) When adjusting velocity in mid-air, Belmont only accelerates slowly (rather than changing direction instantaneously).
5. Additionally, a `vcancel-only` patch is provided which makes only the `vcancel` change and no other change.

So from that I understand the following:

• [Vcancel] Contains features 1, 2 and 3.
• [VCancel Only] Contains only 3.
• [NoVcancel] Contains features 1 and 2.
• [Inertia+Vcancel] Contains features 1, 2, 3 and 4.
• [Inertia+NoVcancel] Contains features 1, 2 and 4.
