I just recently had a leaked CR2032 inside a Mario Paint.
The PCB was covered in acid from the battery and was a pain to clean.
A friend of mine also had a battery explode in his hands while desoldering it.
Nothing happened though but the risk is there.
I'm changing them when their voltage is below 3V or if they look bad.
I mean they're 30 years old and probably would last another 10 years or so, but safety first.
Damn just saw this topic.
Recently became a huge Doctor Who fan as well since they're airing it on TV.
Watched all of the episodes with Capaldi, Tennant, Eccleston, Smith and Whittaker and from most to least favorite, here's my list:
1. Peter Capaldi
2. David Tennant
3. Matt Smith
4. Christopher Eccleston
5. Jodie Whittaker
Have yet to watch more episodes and other doctors to judge about them.
I hope they're bringing out more seasons of Doctor Who!
This is just a fix to keep SRAM voltage steady to avoid corrupted writes when power is off.
Usually 22uF decoupling caps are added between VCC and GND on the main board and also another 22uF between SRAM VCC and GND as seen on most boards that have SRAM.

Therefore, it's the US proto ROM with no expansion audio.
Besides, adding the circuit in a NES cart/console is more tricky since you will have to use 2 of the EXP pins, create the circuit using AY-3-8912 or 8910 and also mod your NES to play it properly.
Some collectors are just picky and I don't blame them with how many repro carts of the more expensive games are there lately.
Personally, if I have a cart with completely damaged label, I don't mind if it's remade.
Well, around 80-200 USD, depending on condition, completeness, etc.
It is convenient but one should ask themselves if they want to do it.
Just my two cents. In the end it's your decision and if you decide to go for it, good luck!
Is the game played in the proper region?
PAL game on PAL SNES
NTSC game on NTSC SNES
Have you tested another SNES, if you have one?
Looks like your SNES does not like the DSP registers which would be the CPU or PPU.
Might want to try get a Burn In Test Cart (a repro works fine) to test the registers.
