that would be very interesting to see.it'd be cool if someone built an RTC replacement around an ESP32, no battery and use the onboard wifi to get the current time on boot.
I hope someone can come up with a fix. These chips are costly to replace and are all dying so the battery mod works for now, but a permanent solution to bypass that check would be even better!it'd be cool if someone built an RTC replacement around an ESP32, no battery and use the onboard wifi to get the current time on boot.
Download the files from the game that are dumped in mame. Inside the zip will be file needed to be programed to the rtc. I can't remember though, some of the konami games can write to the rtc on boot if you hold test or somethingDoes anyone know what file I need to fix the RTC??
Looks like enough to solder to. If you look at my pic, the red wire is positive. So in your pic(since upside down) the left is positiveHow do I know what side is positive and what's ground? And is this enough to solder to??
Any idea why this is failing? Always fails to verify in the end by 1 or 2 differences.
The fact that it's failing means it's working, the clock is advancing.
This sounds like where it broke then.It was "successful" now
