New WOZ 75th anniversary edition owner here for the past couple of months and loving it!

I keep seeing recommendations to get the munchkinland protector but playing the game I just don't see it. I was planning to get the scoops and kickouts protectors and skip the rollovers/magnets and the munchkinland one. Can you help me understand what the munchkinland protector protects? My balls don't seem to be hitting the edge of the upper playfield if that's the purpose of it.

Thanks

PS: I have another issue with the left flipper that I'll be posting for help if I don't first see a solution to it in the forums (weak flipper that simply collapses when the ball hits the edge - kind of like the weak flipper mode but happening when I'm not even in that mode).

Looking closer I *think* I see a slight chip on the edge right next to the ramp. I'd have to pull off the glass to verify but it does look like it is chipping there I wasn't looking forward to taking the upper pf off.

Thanks for pointing this out! I wouldn't have known until it got progressively bad, or even worse in the other portions of the upper pf as others are saying.

This is a dumb question but the software version on my WoZ is 6.10. The JJP support site has a delta update going to 6.61 from 6.06. Can I still upgrade from 6.10 to 6.61? Or will I need to install 6.06 and then go to 6.61?

Another question is the USB stick that I'm using. It's a Sandisk Cruzer and it has a folder containing 2 PDF's and an executable. Will these interfere with the update? I've seen posts from others having issues with the update and some were attributed to the stick not being entirely empty.

Thanks!
