This command will delete any older kernels that aren't used anymore:

sudo apt autoremove

I wouldn't delete any files on /boot manually, as this can easily break your system.

How much space do you have free on your /boot partition and how large is the file you're trying to copy ? On a regular RetroPie install, the boot partition is 36M, with only 22M taken. A regular Linux kernel has less than 5M, so any driver should be able to fit into the 10M left.

@mitu Did the size of /boot change in Retropie since April 2018? Because the /boot partition of my stock Retropie 4.4 that I installed in April 2018 has a size of 57 MB.

$ df -h | grep boot
/dev/mmcblk0p1   57M   40M   18M  69% /boot

@Clyde Actually I was wrongly reading the numbers - 36M is the free space. So, indeed, the bootpartition is 57M (the Raspbian default), with only 22M taken - a whole 36M free on a default install.

@mitu Thanks for the clarification. There may be less free space on an regularly updated Retropie like mine. I wondered why my /boot has 40M used space although I cleaned it up with sudo apt autoremove. Apart from the kernel and the firmware files start*, the only files that are bigger than 1M are firmware files for the RPi 4 (start4*, see https://www.raspberrypi.org/documentation/configuration/boot_folder.md), which should be new since the RPi 4 didn't exist in 2018.

(I don't know what the overlays directory is doing there.)

Sorry for the digression while we're waiting for @artgamer2009's response. 😇 But maybe it can help him/her to know the contents of /boot in a Retropie installation that's running and updated for some time. I'll have to say though that I did compile some additional files from Github repos like WebtroPie, dispmanx_vnc, gunconf etc., so I don't know if that added something to my /boot that wouldn't be there otherwise.

@Clyde hey thanks for the help! I do not have my raspberry pi at my sight but when I do, I'm really going to tell how it was going again thx for the help!
