Restore with new 64 mb chip failed #29

Ch1n01 commented 2 years ago

Hello! I had 2 consoles, I backed up first console, unloked, changed the chip to 64 mb, restored the backup, recorded a bunch of games, everything is fine with this. Did all this in Ubuntu VMware under Mac OS. I also made a backup of the second console, hacked it, left the soldering of the chip for later, made a snapshot in VMware. Later I soldered the chip, and when I started to restore the firmware, I realized that I accidentally deleted the snapshot with the backup. So I decided to soldering stock chip back, made a backup, desoldering it and soldering 64mb chip again. After that when I trying to restore firmware on 64mb chip i am seeing this:

Can I something to do with this? Thanks!

I have created pull request https://github.com/ghidraninja/game-and-watch-backup/pull/34 to fix this.

I know this is a year old by now but could you try with the latest version ? Just prefix your restore command with LARGE_FLASH=1 and you should be good.

Hello Benjamin! Yes, of course, I can check as soon as I get back from vacation in a couple of weeks. Thanks for the answer!

Did it work ?

Ch1n01 commented 1 year ago

Hi, Benjamin! I had a problem with soldering the memory chip on this device, due to the fact that I changed the chips many times and tried to restore it. I will try to solve the problem, if there are results, I will definitely write an answer.
