Quoted from rubberducks:

The only big updates happening to 'old' games are Lyman and Lonnie. Contrast this with the only 'old' Dwight game that had an update .... Star Trek, which had a couple of lines of bug fixes which Lyman helped him with.
Unless he has a lot of assistance from the new hires, i wouldn't expect much for GB. ST and GoT both need bug fixes and general polish, and it seems unlikely it'll happen.
But to this code ... looks good. Can only imagine how much better the game's reputation and sales to collectors would have been if they'd come out with this two years ago.

Quoted from TKDalumni:

Try a different and slightly larger stick...

Quoted from SonicZone:

I've never seen an update screen on SPIKE that looks like your 2nd pic (with that size lettering/font type). It should finish with what's in Stones pic above: https://pinside.com/pinball/forum/topic/new-kiss-code-v1400-is-here/page/3#post-4714371
You'll probably need to give Stern a call, because even if you had the old 1.30 code, I'm not sure it's possible to "roll back" on SPIKE/SPIKE 2 boards. At least that's what I've read.

Quoted from SonicZone:

I've sometimes wondered if there's any reason why you couldn't remove the SD card from the SPIKE2 CPU board (powered off, of course), save its contents using one of the many cloning/imaging tools available for Windows and/or Linux and then put the unmodified SD back into the game? This way you'd have a backup you could get that SD card -- and hopefully, the machine itself -- back to in the unlikely event a code update craps on you and your game won't boot [properly] afterwards. Would something like that work (and, more importantly, would you still have a bootable game if the SD card was in and out of the game like that, unmodified or not)?
