Non-Volatile N64 memory pack

My personal favourite of all of Nintendo's systems is the Nintendo 64, but one of the draw backs is that on some muti-platform games such as Rayman 2 the great escape and Tony hawk's pro skater is that they require the N64's memory pack. I have a few of them however the batteries have died in them. It would be easy to replace the batteries (I have done it a few times before) but I'm just wondering is their any way to mod them to have a non-Volatile memory chip inside the memory pack? or even if their is a possible way to do it.

 

your memory pack need batteries ? I think that you refer to a rumble pack and memory pack combine together. these gadgets only uses batteries for the rumble pack inside. Concerning n64 memory packs, their virtual memories gets used over time and tends to erase its memory alone. what you should do ( as i did ) is just to buy some new memory packs on ebay ( sealed ) from 3rd party companies

 

I suggest buying a Performance brand memory card like this one :http://www.nesrepairshop.com/online_shopping/index.php?productID=744. They have a batter holder built in so when it dies you can replace it with a regular cr2032 battery no soldering. If you want to back up your cards on your computer and if you are using windows xp try a dexdrive.

 

As far as I know the production of Nintendo 64 accessories has stopped 10 years ago. Even if you buy a memory pack as 'new' the battery might be already empty. Here's a good repair guide (in German though):

The only secure solution would be flash based memory pack. Does anyone know if there are any available?

 

You can also back them up and restore them with a GameShark if you still have a PC with a parallel port and an older OS.

Can't find anything on replacing the SRAM chips with FLASH (guess you can be the first!) but there are the occational articles on modifying different kinds of rumble paks so they don't require batteries. Silly question though, but wouldn't EEPROM lifespan be an issue as well?

 

Yes but typically that figure is something like 10k-100k write cycles. You could effectively write once a day every day for 273.9 years before hitting 100k cycles - which means it is far more likely to fail for other reasons first.
