@quicksilver I ended up installing a fresh image and it worked thanks for the replies or I’d still be stuck

@MDtar7 Im running out of ideas, but try enabling SMB 1.0 support on your PC.
Its in Control Panel, Programs and Features, Turn Windows Feature On or Off and select SMB 1.0/CIFS File Sharing Support. Restart your computer and try it again.

@stonemp What did you have to install to get the Atari800 emulation working? I don't care about 5200 but they seemed to get mentioned together. I downloaded RetroPie 4.3 a few weeks ago and followed directions but no-go. Granted, the directions & video I saw were for the 3.7 version of RetroPie.
I have all of the Atari ROMS and a bunch of game images (because I emulate atari800 on my Windows PC).
Is there more to the installation then copying ROMs and program image files?
I've visited a ton of links...there's a sea of information out there I'm drowning in.
What part am I missing?
