The resistors are fine. Just get the battery out, wash and brush the
area and you'll be surprised.
The silver cylinder is a crystal, and that is glue around it's base to
secure it from vibrating. That one is ok don't try to clean that glue
too much.
Doesn't look too bad really but you didn't show all the electrolytic
caps. The larger ones can have corrosion on the traces even though the
cap may look fine at first glace. They don't get the green copper oxide
all over like the battery, they get an invisible film that spreads all
around the area around each one. Yo look real close and you see the
traces may be corroded underneath the soldermask.
Or maybe all fine. First obviously just get the battery out and clean
the area, and then you'll be able to see if any traces need work with
the surface crud out of the way.
Doesn't look too bad though. Should come back fine without too much
trouble. You don't usually have to actually repair traces, just add a
wire from point to point to replace where the trace went. Wrapping wire
is handy for that. Or single strands from some stranded wire.

Okay, a few years have passed. I get it. Things happen. Bought my first
100 in 2020 from eBay - instantly had problems that still exist today
but I've recently identified a solution. Soon after, my second 100 came
to me as an inexpensive 'for parts' unit that ultimately worked fine -
the seller didn't have the memory switch set to 'on' and thought it was
dead. The thing works like it's fresh out of the factory. Guys, I
learned that I made a big mistake. Got my 200 from this list soon after
getting my 100's and made that my daily driver from then on. 100s found
a home in the closet next to the board games.
I decided today to register them all with Web8201 and cracked her open
for the first time. I wasn't thinking too much about the insides, stupid
me, and opened it to get the necessary numbers to provide good
registration info. As I was screwing her back together, I decided to
inspect it for problems. Looked at the battery and, on initial
inspection, it looked okay. Then I looked closer and found residue on
the side, then residue on a number of via's where the nearby resistors
are soldered in.
I should have inspected it two years ago but it just sat on my closet
and I can't help but think maybe it only leaked after i got the device.
Again, I turn it on and it's splendid. I just wish I wasn't so stupid as
to ignore the inspection two years ago. Or, at least, I wish I had at
least removed the internal battery when I got it. Just stupidity here. BONK
So now I have some soldering and cleanup to do. I assume the resistors
should be replaced? I went ahead and excised the motherboard from the
shell for deep inspection. As you can see, there are some leaking caps,
residue, and some impacted traces so... I have some restoration work to
do. And I have some components to order. I also have to learn how to
restore traces.

From yall's experience, is this real bad or not too bad?
