I tested four different carts all had the exact same text in the flash, I also don't know the history of this console to answer that, but it most definitely had all the tabs soldered
unfortunately I haven't found another 2906...yet, and thanks for the img
yes I tried the reset button on all four carts but to no avail
thank you here's the STIC
and thank you all for your help and suggestions I'll keep you updated as this all moves (hopefully) forward
