I'm liking that they are using a joy-con battery to power it, as for storage, I guess it wouldn't be too difficult to just swap out the SPI chip for a slightly bigger one (granted your still pretty limited with it being an spi chip) but as long as the system is capable accepting a larger chip (I wouldn't imagine they didn't bother putting any hardware checks or anything in place) I would imagine you could make up a little 20 in 1 game system for novelties sake, but I guess the limited storage makes the system less appealing to people looking for a little emulation system, hopefully people figure out how to interface with it via usb and can reprogram it whenever they want to swap out games, would make it at least a little bit more useful, but overall its going to be limited to a novelty item rather than a fairly useful little device like the snes/nes mini consoles ended up being useful as a emulator box

based on stacksmashing’s explorations it doesn’t appear as if the USB-C port on the new Game & Watch is connected to the CPU or anything other than power wires. It seems it’s for charging the internal battery only, which means that anyone wanting to swap out the pre-loaded ROM files, or completely replace the firmware, is going to need to open up their device and use custom hardware to re-flash it.

but he sayed on twitter only this:

Didn’t solder a thing - but also didn’t use USB

couple of test clips were enough. Need to check whether USB actually goes to the CPU, didn’t look like it does

can be a bad news i dont now if this site has more infos about

yeah I guess there isn't much need for the game and watch to have a usable USB port, at least with the snes/nes mini they had the reasoning that there was more that could go wrong so they needed a quick recovery mode to recover faulty consoles if the settings or saves or something somehow got corrupted and somehow bricked the console, there isn't really any saving on smb1 to go wrong, I guess that seals its fate as a novelty/collectors item

wouldn't surprise me to see a couple of people refresh the console just for the sake of it, but its not going to be more than just enthusiasts doing it just to prove they can......could see people gutting them and trying to stick a pi-zero in the case or something with a full gb/gbc/nes romset

The process of the hack + some tools have been released.

interesting, so its similar to how we used to have to create xor pads for the 3DS to downgrade the firmware, the sad part is this only works for known data, so unless the entire un-encrypted flash chip is loaded up into ram at some point you would only be able to decrypt and re-encrypt the known areas, I guess the sprites and stuff for the clock would be possible if they figure out what format they're stored in and the roms should be fairly trivial, unfortunately the on the fly patching would probably mean flashing games that aren't SMB is out of the question

then again, if they are using their other systems emulators as a base for the game and watch emulator, you would probably find a nice simple ini file loaded up in the ram dump thats used for applying patches and with a bit of XOR'ing you could find the location its stored at in the encrypted flash image and patch out the patches entirely by simply dummying out the ini file

Looks like the fella has DOOM running on it now, exciting for those of us into these things

can it run crysis

Game and Watch got completely reverse engineerd.
People are also looking into a mod that integrates an ESP32 WiFi module, which could lead to things like wireless transfer of ROMs. Work has even begun on a full PCB replacement that includes an FPGA that can run a NES core.

I must pick one of these up soon.
