Gen 5 Romhacking -- Narc Repacking

[heritorofrain]

Is there a reliable tool for repacking narcs? I've extracted 0/0/8, added a new map to it, and am looking to repackage it, but narctool (the v0.1 nameless file patched) doesn't seem to want to run for me -- I've noticed a few others having issues with the same thing, so I was wondering what might be causing it, such as me not having a script or something installed, or if there's a reliable alternative I can use for Gen 5/B2W2. I have also tried Kiwi, but after creating the narc and reinserting it through nitroexplorer2b, opening the rom up in SDSME gives me an error and will only load the first 170 maps.

Nitroexplorer works thoroughly in reinserting a Narc into the game, and Kiwi works with repacking modified files into a Narc.
(I know this, because I had to do those things to make this happen)

If your game crashes, there's probably some other edit made to the game by some other program, or your tool that is writing to the modified narc isn't working as you intended. (or you just didn't modify the narc right).
