Quick bit of background - one of my friends gave me a box of Super Famicom games - mostly loose carts, but with a few boxed ones. One of the boxed ones amused me because despite being 20 years old it looked like it came off the production line yesterday - not a dent or scratch anywhere on the box or the cart, manual was perfect and all the other stuff was there. Another of my friends collects CIB SFC stuff so I told him he could have it since it was in such great condition. Now is the (to me) strange bit - the game is Tengai Makyou Zero which, if you're not familiar with it, has a real-time clock inside the cart. Since the RTC takes a lot more current than just backing up SRAM does, the batteries in that game are generally completely dead, and this one was no exception. So I asked him if he wanted me to replace the battery with a new one - I have a stock of the exact style of Panasonic horizontal PCB mount CR2032 cells that Nintendo used. He said no, because with a replaced battery it wouldn't be "original" any more. Which is true - but in the state the cart is in, it's really unusable since it loses the save memory when you turn the console off. Are there many people that feel this way, or is my friend an extreme outlier?
