so the European English version is identical to the US one, right down to the ESRB warning?

 

No it's not. US and UK-version appear to share the US-serial internally (not on the cart which always means different dumps on the DS!) but are different versions which was already the case with some Pokemons on the GBA. I guess it uses UK-english instead of american.

 

Is there any difference between these versions? like is the Euro any different from the US beside its sold in another region?

 

It is the European English version.

I tested with my own cart after reading about it (Rom Game serial shows USA):

My cart has NTR-ADAP-EUR as serial printed, but when you dump it (with Rudolphs dump tool) and run it through NDSHEADER 1.4 it says NTR-ADAE-USA as serial

BUT the CRC is different when you compare it to the USA dump
and NO ESRB warning

Same for the Pearl version

So it' not a nuke in my eyes.

 

not a nuke but pretty much pointless

 

It's possible you may need this to import Pokemon from the European GBA carts, or link with PAL Pokemon Battle Revolution however.

 

When does the version for people outside of Europe that speak Outside-of-Europe-and-North-America English come out?

 

Excuse my stupidity, but why does this carry the v.1.13 addage?
Obviously it means it is version 1.13, but is there a Euro' version 1.0?
