Everytime im trying to patch either of these games no matter what the rom is or the patcher its giving me this error "An error has occurred: xdelta3: not a VCDIFF input: XD3_INVALID_INPUT" What does this mean and more importantly how would I fix it if someone could show me how that would also be appreciated

There are two flavours of xdelta and two main faults I would expect
New xdelta
http://xdelta.org/
Older xdelta that was used before the new one came back, and still used in some GUI programs
https://www.evanjones.ca/software/xdelta-win32.html

Neither are mutually compatible it seems.

Problems, assuming you have the right region and version (the pokecommunity one wants me to sign up so meh but the projectpokemon link's readme "First of all, this hack was done with an Spanish Version of the Pokemon White rom.", bonus here is it seems like it comes with the tools to patch it or at least I hope they included the stuff they used to make it)
1) Trimmed ROM. I have been seeing pretrimmed ROMs put out there on the internet. Simple test here is usually is the ROM a power of 2 size (should be 256 megabytes).
2) You got a redumped version, or maybe didn't and it expects the other.

This was earlier days of the DSi dumps (some people dumped as per normal DS games which makes a fine dump even on DS flash carts on the DSi but later the extras available to the DS were able to be dumped) so I have no idea what version the original hackers would have used here.
Two main versions, no idea which you might have or require right now (I could probably find out if the xdelta patch includes an initial hash of what it expects).
Pokemon_Edicion_Blanca_EUR_SPANISH_NDS_DSi-PUSSYCAT
Pokemon_Edicion_Blanca_SPA_iNTERNAL_NDS_DSi-WiKiLEAKS

Even if you randomly got it from another site it might still be the same version, or trimmed.

Not the 1st one unfortunately

Not the 1st one unfortunately

So both the first and second ones did not work?
