Grats, that's amazing. Maybe you can make another one for me?

Just kidding
I don't think there are Amiga haters in Abandonia, don't worry.
In DOSBox press Ctrl+F1 for the mapper, this will allow you to map any joystick/gamepad button or direction to any key, or vice versa, as well as keyboard to keyboard.
Now the PC isn't probably the best platform for arcade-like games with simple controls as you must know, you'll likely want to set up some emulators for Sega, Nintendo etc. But looking at
my AB favorites for these kind of games (they'll have versions for other platforms so you can always choose other than PC if it's better):
- Budokan
- Crusader No Remorse, and No Regret. I'm not sure if arcade controls will be enough for these, but they may, look into it.
- Desert Strike, Jungle Strike, etc.
- Flashback, of course! Blackthorne, Prince of Persia 1, 2, etc., you name it. 2D action platformers can include some good PC exclusives.
- Why not 3D also? Tomb Raider series, etc.
- Relentless/Little Big Adventure/Twinsen's Odissey 1 and 2.
- Moonstone A Hard Day's Knight. Again not completely sure, but you can probably play it with arcade controls. Really nice game. There's an Amiga version.
- Stunts
- Tyrian 2000
- Wacky Wheels!!
And then in this kind of games you can always look at the "If you like this game, you will also like..." For example I just saw Abuse, I haven't played it a lot myself, but it's a really good arcade game. Or you can search Abandonia by tags, hotseat multiplayer... anything (see the "game filters" to the right):
