How to add new pokemon to bw2 without overwriting existing ones

[fakudolan12345]

I saw the tutorial on how to do it on gba games but nothing on nds. I have twisted fatals stat editor and it doesnt have question marks underneath the last pokemon but i know there is extra space becuase there are only 549 pokemon but there is 708 mini narcs in the a016 pokemon stat narc. So can somebody tell me what tools i need, how to and how to add the new pokemon and add new sprites for them. The tools i have are

nitroexplorer2b

PPNFR narc replacer

Twisted fatal BW2 moveset editor

Twisted fatal BW2 stat editor

Ms Paint

Infranview

HxD hex editor

not only using that tool, you need edit ARM9 binary and some OVA is handle for pokemon thing... you can use IDA PRO, and search on this forum for some information about that.

About to look up that IDA Pro, but the same should go for HG/SS, correct??

I dont really understand what you mean. not only using what tool? and ida pro costs $500 so can i just use a regular hex editor? also what parts of arm9 binary and ova do i edit?
