Quoted from bonanza:Sorry if this is an idiot question but I have no electronics knowledge but doesn't changing to a NVRAM eliminate the need for all batteries? If so, why not just stick the $6 chip in that is being discussed in another thread in this forum and be done with the whole battery thing?
If batteries are removed and NVRAM is used the built-in clock on the WPC ASIC will not keep time when power is turned off. Some games have a "midnight madness" mode that depends on accurate timekeeping, which obviously will not pop up as expected. There are also hidden Easter eggs on some games that will display "happy birthday" messages and such on certain dates which will not work without a running clock.
If you can live without those features then NVRAM is a good solution to changing batteries every year.
