Atari 2600 - No launch

[ThaDoctor72]

I may be fighting a losing battle, but I have two RPi's, a model 3, and model B. The newer one works great, but the model B, when attempting to launch A2600 it just goes to a black screen for a few seconds, then back to the frontend.

Only heard of Recalbox 2 days ago, so certain levels of noobishness are accepted, I hope.
Thanks,
