r/gameandwatch

Hey everyone, I made a game & watch inspired roguelike game in a Moomin theme and want to share it with you.

It was initially inspired by Nelsonic Zelda gameplay, but it went far from it.
In game A you have to make few days journey to the north, finding tents to sleep in the upper row of the map. Within few days you will cross a river and enter the moomin house.

Game B introduces hunger system, you have to forage mushrooms to survive. It might be a bit brutal and unfair, you learn by dying in this game.

You can play it here: https://usasha.itch.io/norrut

If anyone is interested in collaborating on graphics design for this game or has suggestions on how to further simplify mechanics (or save screen segments), please feel free to reach out.

You may have seen my previous post regarding my tropical fish game and watch and the strange dullness of the graphics at the bottom of the screen. (Included pic of working octopus unit for reference on how it should look) Thanks to Everyone’s advice I’ve tried cleaning all the parts of the system, as well as trying 3 different polarizers including one brand new, flipping them various ways. And trying new reflectors. The game works fine besides the screen being dull. I’m gonna live with it for the time being but at some point soon I’d like to get it fully operational. I’ve been told in the comments of the previous post that it’s likely a capacitor issue. If anyone has any advice on where to get/how to install new capacitors in these units. Or any other potential causes please let me know!!

Hi, I just bought a Snoopy Tennis on a flea market. I already had one and when I came home I noticed a difference between the 2. The one I just bought has Peanuts in the lower left corner. When I check pictures online I only see ones without Peanuts. Do you have info about it please?

Sorry if the pics arent any good, dont really know how to photograph stuff like this. It works and everything! I myself am a retro gaming collector, but i wouldnt mind selling this at a good price bcuz i have my eye on the funtasric jungle n64 and a gameboy color. If anybody here would mind estimating the price of this thing in this condition or if its worth grading that would be greatly appreciated!

So I just picked up this nice tropical fish game & watch. I put a new polarizer and reflector on and it looks great the problem is the screen only looks good from a certain viewing angle. Which is way lower then that of my other game and watches (put dkjr pic to show) and was wondering what I should do to fix this. Especially since I don’t want to mess around the zebra cable unless absolutely necessary

forgive my mediocre blender skills, this image came to me in a dream and i had to create it

So I want to repair these but have no idea what type of screwdriver I need to open them.

As gaming technology goes, it doesn't get much simpler than Nintendo's Game & Watch LCD handhelds. But emulating them accurately, and preserving them digitally, is such a challenge that Nintendo itself hasn't even entertained the [ide]. We meet the MAME benefactors who've devoted their time and talent to doing what nintendon't.

Retro Reversing → How MAME Emulates Game & Watch
Game & Watch emulation in MAME is hardware emulation, not game reimplementation. The actual machine code dumped from original Nintendo microcontroller chips runs unmodified. MAME replicates the Sharp SM5xx CPU, the LCD segment controller, multiplexed inputs, and piezo buzzer - the game logic follows automatically.
