First of all, yes it's a hentai game. You can believe it's for my girlfriend or not.
I asked her if she'd like a Steam Deck and she said it fits how she'd probably play games, but she wants to play a bunch of games she got off MangaGamer and she wants to make sure they'd work on the Deck.
I have a thinkpad running Fedora so we installed one through WINE to try it out. Everything is working but all the text are these squares for missing characters.
Is there any easy way to install fonts and characters for WINE, or will we need to look at something like the ROG Ally instead?
Looks like you need winetricks to install CJK_fonts.
This is what fixed it, thank you. It must be that although the game is in English, it's using the English characters from a Japanese font and character pack. Now I know what the issue is, playing these games on the Deck is more possible
