Lord of the Sword - 4
Shinobi 2
So 36 with all the other games, if shipping doesn't increase.
In terms of shipping, you're close to the 1000g (1kg limit). You're sitting at 904g without the envelope (I'll find out how much those weigh today).
I have the cases for all the games you want except for Mega Man 2, and all the cases weigh about 100g. So, it might happen that not taking a case or 2 might save some shipping. It's something to think about.
EDIT: If I use a bubble-wrap envelope, shipping will not increase.
