Their original RAM solution was to provide a ZRAM with a unreachable battery that could be placed.
Results is a Maverick that will not work.
The first solution to try was to connect an external battery to a RAM chip and plug that in.
The final solution was to replace the existing RAM chip with a FRAM chip. It requires no battery and runs for years emulating a battery assisted RAM.
Just plug it in, run a clear chip, put the game chip back in and turn on the game.
If the game won't boot it is usually because the small voltage control pot in front the power supply components is not adjusted properly.
Play with it till the game boots up.
WE have 10 spare FRAM chips that have been tested. we are willing to sell up to 4 FRAM chips, the rest we are keeping.
