The Soul Silver SID you gave me worked perfectly. Thanks! Haven't checked the Heart Gold one but will assume it's also pristine.
As for you Gengar, I don't have a Substitute or Focus Punch TM handy (made a few Brelooms lately), but the core will be complete. Here's his stat lines:
Male (So you can pass down precious TM's if you wish to make another build.)
IV's : 31/31/30/30/31/30
Hidden Power: Fire 70
No Ev's put into it, and not given Pokerus
I'll be able to trade it to you sometime around 6. Later!
