Sure, but like...would it really be the end of the world if it got controller support? I'm far more comfortable on controller than I am on mouse and keyboard, largely because I work on mouse and keyboard all day.
It would be very difficult to control a game like Fallout 1 with a conventional controller, but if you really need it you can use DOSBox, which has controller support. The Retroarch core is probably the easiest to use and setup, I am not sure about the standalone version, but it is probably similar.
add it to steam as a non-steam game , if you use that for other games, and try to create a mapping with Steaminput. I have not done that for fallout, but that offers so many options that i am certain you'll be able to map everything to your controller you need.
If steam is not an option xpadder or joy2key might work for you, but i have not used them for ages.
You're best bet is doing that commentor's suggestion. Those games do not map to a controller that well and most likely will never officially receive that.
Without official support, I doubt they'll ever map that well at all, but I've got an ergonomic mouse in the meantime. Official support would still be better though. Games that only work on mouse and keyboard will be a smaller and smaller library as time goes on, if all goes well.
Steam Input lets you map the trackpads to a mouse and you can map the buttons to any keyboard button. You can even map a zoom button and force the game to a specific resolution. It’s doable if you believe in yourself haha.
What I need is a larger UI so I can fucking see what the hell I'm doing. I got like 6.25 glasses and astigmatism, and I guess I should qualify as having a visual impairment because fallout 1 is unplayable
Well support might not be an option but have you considered/tried something like xpadder? I had to use it to map keyboard buttons to a controller for gameboy emulators a couple years ago. Might do the trick.
