Hacking and Flashing Game&Watch (Zelda, linux VM)
Рет қаралды 14,497
In This video I'm (again) going back to hacking and flashing Game&Watch - and this time it's Zelda variant. Just as in my most recent video I'll be using linux VM as I think it's a faster and more convenient.
Here are the links to my previous videos on Game and Watch hacking:
Mario variant, dual boot, linux VM: kzfaq.info/get/bejne/d5aEZZl1v9q8mqs.html
Mario variant, dual boot, RPi: kzfaq.info/get/bejne/h9iampqJ1LzXm6M.html
Zelda, retro-go only, RPi: kzfaq.info/get/bejne/eKyGocypkqqaYGQ.html
Here's a link to VM image I'm using. It contains all the tools you need, including a script I made to help with coverflow artwork.

Here's a link to ST-Link device I'm using (colors may vary but it's the same device):
amazon US: amzn.to/3ls1qXp
amazon UK: amzn.to/3XxCpYi
I'm using MX25U51245GZ4I00 chip. Full list of compatible chips is here: www.reddit.com/r/GameAndWatchMods/wiki/flash-upgrade/
Here's the link to the page where I sourced the pinouts from - it's a very well written and well worth reading page (note that it's not dual boot so you may need to follow the video if you want original games and retro-go):
community.element14.com/challenges-projects/project14/hacktheholidays/b/blog/posts/the-n-o-before-christmas-upgrade-time
Here are the commands I'm using in the video (Zelda):
--- Backup and unlock
./1_sanity_check.sh stlink zelda
./2_backup_flash.sh stlink zelda
./3_backup_internal_flash.sh stlink zelda
./4_unlock_device.sh stlink zelda
./5_restore.sh stlink zelda
--- Patching of original firmware
make PATCH_PARAMS="--device=zelda" LARGE_FLASH=1 ADAPTER=stlink flash_patched
--- Generating artwork
make_covers.sh nes
(repeat for each system you want to flash)
--- Build and flash retro-go
make romdef
make COVERFLOW=1 GNW_TARGET=zelda EXTFLASH_SIZE_MB=60 EXTFLASH_OFFSET=4194304 INTFLASH_BANK=2 flash
And here are the commands you can use if you have Mario variant (covered in previous video):
--- Backup and unlock
./1_sanity_check.sh stlink Mario
./2_backup_flash.sh stlink Mario
./3_backup_internal_flash.sh stlink Mario
./4_unlock_device.sh stlink Mario
./5_restore.sh stlink mario
--- Patching of original firmware
make PATCH_PARAMS="--device=mario" LARGE_FLASH=1 ADAPTER=stlink flash_patched
--- Generating artwork
make_covers.sh nes
(repeat for each system you want to flash)
--- Build and flash retro-go
make romdef
make COVERFLOW=1 GNW_TARGET=mario EXTFLASH_SIZE_MB=63 EXTFLASH_OFFSET=1048576 INTFLASH_BANK=2 flash

I just want to drop by to say thank you. Your video helped me to Jb my game and watch Zelda. It took me half a day because I lifted one of the pad on the motherboard when I tried to remove the original memory chip. However all is good now. I managed to save it.

In case of someone can't make VM image to work on windows 10 with vmware workstation (and trying for hours like me), there is a workaround about the issue that says that "this image is not compatible" etc. All you need to do is just load the image and don't run it yet. Then go to the upper bar and choose VM-> Manage-> Change hardware compatibility and just follow the steps from the window that will open. Then choose to fix the same vmx file and you are done. Now you can run the image successfully.

Ps: If ubuntu run sluggish, then go to VM -> Settings -> Display -> 3D graphics, and uncheck that box. Then ubuntu will run normally.

Thank you for your guide! Using the VM images you provided it went flowless till flashing retro go with also patched original software (25:20 minutes:seconds). Even keeping holding the power button, I have an endless loop with "state: FLASHAPP_INIT" that repeats over and over without ever stopping. Do you have any advice on how to do it? Flashing the original firmware, patched firmware or just retro go (without original software) is done without any problems. But if I try to flash retro go AFTER original patched for dual boot, I get this bootloop. A thousand thanks!

Is there a command that checks, if the total size of roms and covers, is within the limits of the 64mb ? That it warns you if you have too much data for the custom firmware ? It seems after the custom firmware build, it says something about the Capacity, Usage and Free space, but that's after the build, would be nice if it warns you before it starts building it.

@seanocansey2956 6 ай бұрын
Hopefully, this is not a stupid question.... but if every Zelda game and watch is shipped with the same firmware, why isn't there a generic backup file of the original flash content? Is it because of copyright laws, or does every device have a unique serial number?
@seanocansey2956 6 ай бұрын
Because if the microcontroller and flash chip are whipped, there would be no way for the mcu or flash to know the origin of the .bin files, so is it to protect yourself from copyright?

After successfully flashing a G&W Mario, I wanted to flash the Zelda version. Unfortunately I get this problem: Hash mismatch in FLASH. Flashing failed. Flashing chunk 14 failed... power cycle unit and retry? (y/n) Unfortunately it is not possible to continue. I have already created a new image, but without success. This error always occurs: Preparing chunk 15 / 64 in file /tmp/flash_chunk.SctPqW Flashing! . . . Starting flash process Please see the LCD for interactive status. State: FLASHAPP_CHECK_HASH_RAM Hash mismatch in FLASH. Flashing failed. Flashing chunk 14 failed... power cycle unit and retry?

I also had this error when recopying games. Start at the point where you restore the backups. After the process you should see something on the screen again
