Hack description

These hacks converts the Konami GB Collection Vol.4 (Europe) game into standalones ROMs by autobooting straight into the games.

The games are:
- Antarctic Adventure
- Castlevania II: Belmont's Revenge (no speed hack, just the autobooting)
- Gradius II: The Return of the Hero (aka Gradius: The Interstellar Assault in America and Nemesis II: The Return of the Hero in Europe on their GB releases)
- Yie Ar Kung-Fu

You just have to use one ips patch depending on the game you want to autoboot into.

Created by reverse patching the dACE ( https://retrohackers.net/hack-details.php?id=2474/ ) and Silver X ( https://retrohackers.net/hack-details.php?id=213/ ) patches for Castlevania II, so credits to them too.

Known issue:
- Soft-resetting any of the patched games (A + B + Start + Select) will take you to the actual Konami GB Collection Vol.4 title screen.

Standalone Konami classics for GBC	Nokia3310	2021-12-01	Version 1.0
Great work. This is a better way of presenting these games than having them as part of a compilation cartridge rom. Sure, there are good business reasons why they were originally sold that way but playing them now means knowing which compilation they appeared on... or at least it did until this. I would suggest doing the same for the Japanese releases of this series (they were Super Game Boy versions instead of GBC) only the Super GB borders are wretched looking things that nobody really wants to see beyond being a curiosity into 90s graphic design. The only gain with having the original Super GB versions are custom palettes. I think it's best to leave those in the past as what they were. More to the point, Game Boy fans can now have these in their digital collection as the standalone games they deserve to be and it makes accessing them easier too. I'd guess that a lot of people don't know what the specific titles were or that these GBC versions exist.
