The code request system is for requesting codes to be made, not for requesting codes to be added. That's what your thread is for.

How did I come up with this? Well, the NES has limited ram space, so most nes carts use mappers to swap pages. When you use a six digit nes genie code, the code edits the target byte on all pages. That's why there are 8 digit codes, that include a compare byte, so the code potentially only edits a byte on one page.

How do you find the compare byte without playing the game? You load you rom into my NESTool, then it tells you which bytes you have available as compare bytes. Considering this code is a "start with" code, it's most likely on page 0. They compare byte for page 0 is 0x00, which makes sense since you'd start with the lowest level bike normally. So, you throw 00 in the compare box, and you get a new game genie code that doesn't interfere with the rest of the game. Imagine that.

LEARN. Six-digit game genie codes are only good for games that are < 24k that have only 1 PRG page, e.g. SMB.
