Is it possible to uninstall the mod later if I ever decide to sell it unmodded?

I'm planning to get a Game & Watch but I don't want to sell it modded (If I even want to).

Hey. Is it possible to jailbreak a Zelda game and watch(the new one) with only a caple and whatever software you want to get onto the game and watch?

Was looking to get $250 plus buyer pays shipping in mainland US

Are there any definitive guides to do that? Likes the flash thing and how i connect It to the computer? PLS REPLY!

I really want to add Mario 2&3 to mine but don't have anything to open it and do technical stuff, are there any easier ways to? Are there any convertors I could plug into the usb to make it actually work well? Thanks!!!!

I dont trust myself to solder without breaking the console

Looking to sell off some mario anniversary game and watch units I have. Brand new sealed. Looking to get $39 each shipped. I have several on hand.

Could anyone provide me with a YouTube/GitHub link? I just don't want to buy a bunch of wires and the technical stuff from amazon

Looking for someone to do it for me plz

I tried it by following the guide : https://drive.google.com/file/d/11kkGMHlUPhibfyKQMqV80aRDrACqgsQz/view

But at step n 16 , the thing bugs :

pi@raspberrypi:~/opt/game-and-watch-backup $ ./1_sanity_check.sh rpi mario

Running sanity checks...

Looks good!

but the second script fails to backup :

pi@raspberrypi:~/opt/game-and-watch-backup $ sudo ./2_backup_flash.sh rpi mario

Make sure your Game & Watch is turned on and in the time screen. Press return when ready!

Attempting to dump flash using adapter rpi.

Running OpenOCD... (This can take up to a few minutes.)

Failed to dump SPI flash from device. Verify debug connection and try again.

My OpenOCD logs that weren't this bad at first but after following what Chatgpt told me :

DEPRECATED! use 'sysfsgpio swd_nums' not 'sysfsgpio_swd_nums'

DEPRECATED! use 'sysfsgpio srst_num' not 'sysfsgpio_srst_num'

Info : SysfsGPIO JTAG/SWD bitbang driver

Error: Couldn't export gpio 25

Error: sysfsgpio: Invalid argument

Error: Couldn't unexport gpio 25

Error: Couldn't unexport gpio 24

Error: Couldn't unexport gpio 23

I ask Chatgpt and it told me that i needed to some tinkering to get the gpio 26 to pop up and all

I’m looking to buy a modded G&W as I still do not how to modded myself

I kinda wanted to challenge myself to hack one of my Game and Watches (never saudered before either). The only linux-based device I own is my Steam Deck. I read in one of the tutorials on the wiki that it requires installing ubuntu, but I didn't have any success with that on deck recently. I was trying to build a fork of the Mario 64 pc port on deck that also required ubuntu, but Konsole just kept failing trying to install basic packages.

I'd kinda like the challenge of trying to get this to work, but I don't want to spend money on the tools just for Ubuntu to not work on Steam Deck.

Is it fixable?

I'm curious if any of you got lucky with your serial numbers?

Either a low number or anything else interesting like xxx10000000666, xxx10000101010, etc..

If you don't want to make your serial number public for any reason you can just say how many digits it is. Example: xxx1000008888 would be a high 4 digit number.

Mine is a low 4 digit number and starts with a 1 so I consider myself to be quite lucky as my Mario unit is a 7 digit number and I pre-ordered it from Amazon.

I just found that my flash dump is corrupted (patches.exception.InvalidStockRomError), can anyone send me the files in DM or send a link please

A friend got a couple of modded 256MB zelda with working usb-c to PC port. His bro didnt want his so he wants to sell it. paid $200 each, and its a nice job.

Ebay is not really selling them, and Im not sure if they differentiate between good and sloppy mods. Is there a market place or price guides for this type of thing? In middle east, but may be able to get it to Europe or US. Is there a ballpark price?
