This mod disables the NES console Lockout Chip. The mod enables playing Import Japanese Famicom game carts in the NES with a adaptor that does not include the 10NES chip. A huge library of Japan only Nintendo games to discover. Another benefit is the reset flashing light boot errors is now fixed for NES carts.

As I understand it the adapter would have to include a 10NES, because the famicom boards used with them weren't modified in anyway and the console's 10NES has to connect to another 10NES to let the game run.
If the Nintendo adapters do include a 10NES chip then I wouldn't have to disable the console's 10NES to play import games.
Not that there aren't other reasons to disable the 10NES in the console. Blinking...grumble...grumble...resetting 'cause someone bumped the system...grumble...
After this mod is completed, you would need a 60 pin to 72 pin game cart adaptor.
There are adaptors to convert both the 60 pin Famicom and 72 pin NES game carts.
An inexpensive way is finding Import Adaptors already inside certain NES carts.

Game Genie
The notorious NES Toaster console contact killer. Since there is no "bend" due to an awkward angle game cart on the end, the Game Genie can fit the FC Mobile II. However, it is a little tight and can still bend the pins open too much. Looking closely, the Game Genie contacts have a thicker plastic on the PCB compared to a NES game cart. It does not bend the portable springs at an angle as in a NES Toaster, but still can cause permanent damage.

Dr Mario NES Cart Connector Thickness - .04"
Galoob Game Genie Connector Thickness - .07"
I never leave a game cart plugged into a console or portable. The system cart connector's spring contacts may retain memory and not pop back out for another game cart.
NES Disassembly
CRTGAMER wrote:To discharge any stray electricity in the capacitors, unplug the NES, press the power and reset buttons on and off a few times.
1. Flip the NES console upside down. Remove the five screws holding the two haves together. Turn rightside up and remove the upper shell.
2. Remove the the screws holding the upper RF Shield and remove the shield. You can now see the cart slot and how the push lock of game carts in the slot works. A closer inspection reveals why the pins eventually fail from the constant pushing up and down.
3. Remove the screws holding the cart slot and PCB. Note that two of the screws on the cart slot are longer, remember where they go. Don't forget the two lower screws by the RF modulator.
When lifting the PCB, be careful not to strain the electrical cables. The cart connector does not have to be removed from the PCB, lift out as one unit. If the cart connector is defective, it is an easy repair or replacement, just slide out. The Nintendo brand connector might be of a better quality metal over an aftermarket replacement. It is best to try to repair by slightly rebending the pins.
4. Carefully lift the PCB and flip over, watching the electrical cables. The blue connector can be removed, it might interfere with the lower RF shield. The smaller connector is fragile, avoid unplugging that one.
5. Identify which chip is the lockout chip. Various NES models have different numbers, look for a couple of features.
- "Nintendo" is stamped on the chip
- PCB has "U10" and "CIC" next to the chip
See the pic below, I have a small jewelers screwdriver pointing to the chip at the lower right.
