v1

How to use it:
-Use the latest melonDS version with the japanase version of pokemon black 2 (I didn't test white 2 but it should work)
-When the game is loaded start the "PokemonBW2TextHook.exe"
-Setup your windows like this:

-Just ctrl-v to the translator (or any other side) and combine with Yomitan to get kanji definitions.

Download this if the program does not open: https://dotnet.microsoft.com/es-es/download/dotnet/thank-you/runtime-desktop-8.0.13-windows-x64-installer

I added a version with UI. Both work the same, but one is prettier, although it weighs 32 MB:

Knowns bug:
Holomisor calls and the intro are not hooked (It's too many work, if someone want's to do it, open a issue and I will help)
