UPDATE: went into deck performance settings and at the bottom hit reset to default, fixed all slowdown issues. No individual setting changed in the performance tab so idk why it fixed it but it did. If anyone was facing similar slowdown issues like myself give that a try.

Every title runs slower than original clock speed. Noticably slower with the audio glitching the entire time.
works out of the box.
saves are good, the controller works perfectly, no issues were found.
Everything is good. Only caveat is the main menu's audio player. You won't get any sound. Same with Proton an GE 7.38.

Perfect using Proton Experimental flatpak community build 7.0-20221012
All 4 games work flawlessly on Steam Deck with no tweaks or edits. Consider awarding Plat status.
Possible controller issues, but otherwise all 4 games work great.
Steam Controller worked without issues, but using my Logitech F310 the game would frequently just start reading right on D-Pad for no reason.
Seems to run just fine so far
1.5 hours into CotM
Loaded my Circle of the Moon save from PC and ran around the castle. Nothing looked out of place and ran great.
Runs just how you'd expect, with no issues at all.

Proton-6.20-GE-1 GloriousEggroll
Proton-6.20-GE-1 Note the fix for Castlevania Advance Collection was only merged recently so this is the first version that includes it. Before this, it was only available in a fork of Proton-GE

Proton-GE-CVA-FIX GloriousEggroll
Needed to create a small patch to bypass file issue, patch and compiled release (based off proton-ge-6.19) below
Release: https://github.com/Raptor85/proton-ge-custom/releases/tag/Proton-GE-CVA-FIX
Audio player on main menu does not change song, in-game audio works fine.
Error: No space available

Game won't work on either official Proton or Glorious Eggroll (unlike what's said below)
I've been able to launch the game through Lutris (Wine Steam) though. Enable Esync & Reduse PulseAudio Latency through Lutris' options to fix audio glitches.

Same result as almost everyone else
Basically a popup that complains about no space being available.
Tested with 6.18-GloriousEggroll-2 and Proton 6.3

Games won't launch but menu works
Whenever a game is launched a popup that says "NoticeMsg__CONFIRM_NO_SPACE_STORAGE” appears.

The game executable starts up, but the moment the window is generated, it is forcibly closed and does not work at all.
I tried changing PROTON_USE_WINED3D, PROTON_NO_FSYNC, PROTON_NO_ESYNC and other possible options, as well as Proton version Experimental/6.3-6/5.13-6/etc... but the behavior was the same.


Games don't launch due to autosave feature
infinite error dialogs: "!NoticeMsg__CONFIRM_NO_SPACE_STORAGE" & "!NoticeMsg__CONFIRM_SAVE_FAILED"

Unable to start game due to popup menus
Upon launch, I ran into two alternating popup menus with an error message. If you hit accept, the other one shows up instead. After quitting and re-starting, I was able to view the main menu, however trying to select a game led to the same infinite popup loop.

Can't play any of the games, can't write to disk.
whenever I try to start any of the games a messages showing "!NoticeMsg_CONFIRM_NOSPACE_STORAGE" shows up and I can't continue nor got back to the menu screen.
