Quoted from Pinballdad1961:I recently uploaded the new 1.21 code into my Munsters Pro and the game randomly stops playing. I suspect the flash drive is the problem so I downloaded onto a new flash drive, but the machine does not see “new” code when it starts up. I tried incorrectly uploading Premium code, but it doesn’t see that code either. Other than getting a SD card writer, how can I reload the 1.21 code into the game?
It should go into code update mode when you boot with a thumb drive, no matter the version of code on the drive. I'd try the other port first and then try wiggling the drive a bit in the port to see if you get a better connection. Had an issue recently where the port wasn't recognizing the wifi adapter, but playing with the positioning fixed it.
