We noticed a recent OS update meant the game stopped working on Steam Deck, and now Ray’z Arcade Chronology is working again, we launching a fix for Darius Cozmic Collection via a beta branch until January 8th.
There's also a test running for G-Darius HD too!
If you have a Steam Deck and would like to participate, the details are below.
Right-click on Darius Cozmic Collection from the library page and select "Properties", then select the "BETAS" tab, and enter the password "FATTYGLUTTON".
We've checked all 4 titles, with no WARNINGS, so brave Silverhawk pilots can safely fly into next zone, but if you notice anything, please let us know here!
