No probs. I know what it’s like with young kids. It gets a little bit easier when the youngest (in your case both ) gets about 3 - 4. But indeed even then with work and other stuff going on it’s hard to really spend late night hours (and hours…) on this stuff. (Other than risking your relation/marriage in the proces…).
That said here’s one vote up for looking into the MAME lag, and one vote down for the Snes9X2002 lag!
