So I got a bluetooth controller as a gift but as I was looking for keymappers, either they were not free or they aren't working as i would like them. And I would really like to use it for some games that do not have "built-in" controller support, but because they don't have that much buttons they would be easily mappable. Thank for the replies in advance!

Tap Tap, is a a great app for people who love games to share their thoughts on games and their gameplay learn tricks and participate in game tests. Now, when you open the feed, it's just pictures of  sexualized characters and bunch of losers fantasizing and jerking off. Tap Tap should address the issue and make it stop, we come here to get info about games and stuff, not to look at naked anime girls and comments like "🥵🥵 I wish she was my gf".
