Castlevania Anniversary Collection

This consists of a series of scaling and aspect ratio mods for Castlevania Anniversary Collection. It doesn't have any 3D feature at the present time and it needs dgVoodoo to convert DX9 to DX11. Tested with "dgVoodoo2_62" version.


Features (all of them are optional, but some of them are enabled by default)
- Perfect 1:1 pixel aspect ratio.
- Optional 4:3 aspect ratio intended for the NES and SNES games. It is pixel perfect when the size multiplier is x6 (or multiples of x6). This is what you get with the F4 hotkey when your resolution is 1440p.
- Quick switching to the highest integer multiple that fits the screen vertically. This doesn't break menus and it detects automatically the native resolution of each game console.
- Point filtering or anisotropic filtering for the scaling feature. Point filtering by default, which provides clean and perfectly sharp pixels.
- Game size multipliers, from x1 to infinity, no matter if it fits the screen or not.
- Output size is always at 1920x1080 by default even if the desktop resolution is higher (you see black bars) or lower (cut content in the menus), with any aspect ratio. This is because all other resolutions in the Collection are either an upscale or a downscale and not really running at those resolutions. What I do keeps pixels clean and perfect.
- All the previously mentioned game size scaling features are done with an external shader that upscales the entire image, but it's only enabled under certain conditions (for example, when menus aren't visible).


Known issues
- My upscaling methods aren't prepared to deal with the filters you can choose ingame. Don't use them. Also keep in mind that it doesn't matter what aspect ratio you choose in the game, because my mod converts all of them to 1:1.


Installation
- Download this file and extract its contents in the "Castlevania Anniversary Collection" folder, where "game.exe" is.
- Download the latest version of dgVoodoo. I have tested the "dgVoodoo2_62" version. I can't ensure my mods will work with a different version.
- Copy the "D3D9.dll" file from the "MS\x86" dgVoodoo folder to the "Castlevania Anniversary Collection" folder.
- Open "dgVoodooCpl.exe" to configure the game like this (better not touch the texture filtering option):

- After applying the settings, it should have generated a "dgVoodoo.conf" file in the "Castlevania Anniversary Collection" folder.
- Launch the game.


Hotkeys
- F1: lower scaling multiple. x1 is the minimum. Overriden by the F4 hotkey if it's used.
- F2: higher scaling multiple. No limits. Overriden by the F4 hotkey if it's used.
- F3: unmodified emulated game size. It is modified to x1 size by default.
- F4: highest integer multiple emulated game size. Not enabled by default.
- F5: 4:3 aspect ratio, intended for the NES and SNES games. Not enabled by default. It can still affect the image if you use the F3 hotkey.
- F6: switch between point filtering (clean pixels) and anisotropic filtering (smooth and blurry pixels). Point filtering by default.
- 5 (not the numpad): this disables the corrected output size I made. Keep in mind that all the other hotkeys count on you leaving this setting untouched.

F10 resets all settings to their default state.
