Part of this has been the effect of having over 600 different carts already. When you've got that many, it gets very hard to find ones that you don't already have. I've picked over all the local shops and pretty much have all the games that they have.
Another reason though has been the fact that my local shops just haven't been getting much new in these days, at least as far as Famicom carts go.
Today though I was quite pleased to find a crate-full of newly arrived Famicom carts freshly displayed at Omocha Souko for me to go through!
On going through them, I was even more pleased to discover that they had some carts which I needed! Yay!
I ended up picking up 10 0f them, pictured above. Among the new haul were such luminaries as Mitsume Ga Tooru:





Anyway, with these new acquisitions I now have a grand total of 647 different Famicom games, 9 more than I had at New Year (the new Lode Runner doesn't count).
Incidentally this is how I keep track of my collection:

I'm so "analogue".
Edited to note:
I forgot to mention the best part! The price! These games were all just 100 yen (1$ US) each! Bargain!
