@Lumpy Very strange, no other user has reported problems with the Atari 2600.
Are you using an original class 10 SD card?
In a clean install of the latest version of Recalbox, the Atari 2600 works well on all compatible devices.
@gamerz719 Burn the system image on a USB stick, and test it on another computer, if it works on another computer, it is some incompatibility of your computer's drivers.
If it doesn't work on any computer, you're doing something wrong when recording, or you're not waiting long enough at the first boot (the first boot is slower, the system creates the SHARE partition at the first boot, so the bigger the storage device, more time consuming)
