I'm guessing you're looking for the coefficients, not the constants. I don't think the wOBA formula changes from year to year in OOTP like it does IRL. So far as I can tell, the formula for wOBA in OOTP is:

wOBA = (.625*BB + .677*HP + .842*1B + 1.222*2B + 1.408*3B + 1.965*HR) / (AB + BB - IBB + SF + HP)

I arrived at that formula using some data from my online league. I transformed wOBA using the denominator in the formula on the website you provided:

wOBA_t = wOBA * (AB + BB - IBB + SF + HP)

I then used linear regression to predict wOBA_t using BB, HP, 1B, 2B, 3B, and HR with the intercept fixed at zero. The R^2 for the model was .9997, so nearly a perfect fit.
