6F49452BD0B343B1 is the BID of both v1.0.0 and v1.0.1, though (the game without the update is v1.0.0). You need to either find cheats for the updated version of the game (Even for v1.0.1, because sometimes even though the BID stays the same, memory still shifts around. The BID is arbitrarily set by the developer by using a random number generator using the TID as a seed, and it is up to the developer if they wish to reroll the RNG for a new BID when updating the main NSO; most do so, however), or (if the latest update is actually neither v1.0.0 nor v1.0.1 and no cheats are made for the latest version) keep using v1.0.0 or v1.0.1 and look for cheats for that actual version.
What's more likely is that v1.0.1 is an extremely minor update that rewrites just one function in order to fix a bug, so they treated it as still being v1.0.0 in-game, but cheats are different, and your cheat file is for v1.0.1. In this case, installing the update should indeed have the title screen say v1.0.0.0 instead of v1.0.1.0.
