Hi - for folks who want to get ROMs, I think this is the safest (free) place to pick them up: https://www.pleasuredome.org.uk/
You need to sign up for the site, but I signed up many years ago, and have never been received an e-mail from them
Only issue is that I am not sure how easy it is just to get one or two ROMS - this is more of an all or nothing thing I think (best have a spare hard drive)
