issues with some Neptunia games

[ahjolinna]

Hyperdimension Neptunia U: Action Unleashed
is opening but you only get black or/and warning window, apparently this has worked with poorly with proton 3.7-3 (for me it doesn't open / launch with older version that I have)

Megadimension Neptunia VII
there is opening cut scene that wont play but you can skip it by pressing the blankscreen at least.
For me the game doesn't seem to be working but it should be not 100% if you need those (32bit) wineprefix for the gameplay or just video

Megadimension Neptunia VIIR
(the VR version the previous game)
apparently audio hasn't been working before but it's here...so not all bad news
except that viewing the intro video doesn't still have audio...for some reason that is the only thing I don't get audio
