Ah, thanks.
With 100% capture rate enabled, my DS parameters are:
VCount: 36
Timer0: 75A
GxStat: 6
VFrame: 15
With 100% capture rate and IV/EV check code enabled, they are:
VCount: 38
Timer0: 75A
GxStat: 6
VFrame: 15
Seems like my VCount was affected but not the rest. The difference in seconds I got were mainly 7 (one 6 out of four results). Soft resetting did not yield any results, so does that mean I must always load the game from DSTWO's menu for standard abuse? Also, since DSTWO's menu does not show the clock to the nearest second but minute, I'll have to sync my DS to an external clock down to the second, right? (Bond was the one who suggested that I buy a DSTWO out of all the flashcarts too, guess I really owe him a huge thanks now.)
Edit: Forgot to mention, the rom I'm using is the UK version (or EU?) and is played in English. Does this affect anything when using the RNGreporter or it doesn't as the language is still in English?
