Castlevania Advance Collection works on Steam Deck, despite what Konami say

Recently, Konami released an announcement on the Castlevania Advance Collection Steam store page to say it does not work on the Steam Deck. It does. Note: personal purchase.

The statement reads: "Before purchasing this software, please be advised that it cannot be played on Steam Deck as it does not support SteamOS.". Clearly then they don't understand how Linux, SteamOS, Proton or Steam Deck works. As usual, I'm here to clear things up — as it really works just fine.

Not only does it work completely out of the box with Proton 7.0-1 on my Linux desktop, it also works perfectly on the Steam Deck (Proton 7 is the default), as I shall demonstrate in the below video:

Checked this one out at many user requests.

Every game in the collection was tested working. Saving and loading with their in-built system also works, as does their fancy rewind feature. It even warns you with a silly screen to mention it doesn't support plugging in earphones / unplugging during gameplay. You should have seen my confused face when seeing that warning screen. That also works just fine.

I can see no reason to skip it if you were looking to buy it.
