I have read on this forum that three games are known to require a working lockout chip in a front-loading NES console to work correctly. These are Super Spike V'Ball/Nintendo World Cup, and Super Mario Bros./Tetris/Nintendo World Cup and Nintendo World Championships 1990.
I recall reading that if there is an issue with the NWC and its lockout chip, it may only rear its ugly head when you reset the console. I tried resetting my SSVB/WC cart again and again in my AV Famicom with a pin converter and I could not get it to glitch, so I'm not sure that it really matters.
The lockout chip in the cart uses four pins : data out, data in, reset and clock. I read the basic description how of it works on the wiki. The lock sends the reset and initialization data to the key and the key returns the correct response. If the correct response is not sent and received, the lock will continuously reset the console.
Even assuming it does not get the data it expects from the cart, the lockout chip in the cartridge should still send the appropriate reset signal to the key and the lockout chip clock will still be present. This may be sufficient to allow NWC to work, at least for the first time you play through the game.
One gentleman got his real NWC cart to work on NintendoAge in a Blinking Light Win modified Sharp NES TV. Another user reports no difficulties with either of the common multi-carts in his lockout chip-disabled front loader. I wondered whether the BLW would cause issues with these carts because it has a CIClone that acts as a key for the lock chip inside the front loader.
