RTC Self Check Error

Lol....I agree if it works. There has to be a better way than dumping and burning these. I couldnt get the pcb to go into test via the dips before, Ill try it with code 1 dispatch since there are not any working dumps of the rtc.
Code 1 dispatch the rtc is specific to the pcb. That is the only Konami Viper to have that protection that I am aware of.
Hyper Bishi Bashi has protection of some sort too
 
Need a little help/confirmation guys,

I got 3 RTC's from mouser for JP3 (USA version). Flashed them all but used a couple different methods.

1) making a device profile in the GQ-4x burner that is based off a 4015. I found the info in a thread on the MCUMall forums

2) As a 2764 (in a socket with pin 1 lifted so it wouldn't get power.)

I gave them to the guy with the JP3 and the first one was no good. It failed on power-up at the RTC self-check. He is going to test the other 2 this afternoon, but in the meantime I have a question:

Is there something else that needs to be done like going into the menu of the game and "re-initializing" the RTC, or something like that?
 
The GQ-4X has the M48T58Y as a supported device... you do need to short two pins while writing it (pins 26 and 28 IIRC - it tells you when you select the chip). Then you should be able to verify the chip to make sure it wrote correctly (will fail at the very end due to the time changing, which is expected).

Thanks, the 2nd chip worked. Not sure if the first was bad or I did something wrong. At least the JP3 can go back on location.

Also, I found mention of holding down the "TEST" button upon powering up the game (in a thread about Mocap Boxing), but I am not sure if that helped.
