TOSECs are a pain to go through, that's right. The only time I used a TOSEC was for the C64, as that's still one of my favorite systems, childhood memories and stuff, so I wanted to be sure to go through everything and not missing out a game I didn't know so far. But pain it was indeed. Once it was done though, I felt like a king ?
Just to mention, I didn't keep every single game though, just the ones I want, still talking about around 2.000 games.
