Game & Watch Core

[LamerDeluxe]

[...] it would indeed be great if the LCD sprites could cast shadows as well, though that might be tricky to do well in fpga.

Not to mention simulating liquid crystal "ripples" if you push too hard on the screen

Yet it will have to be done for preservation purposes

Great to have a complete G&W SM-510 pack. I also prefer backgrounds with shadows and it would indeed be great if the LCD sprites could cast shadows as well, though that might be tricky to do well in fpga.

I noticed Gameboy has an option for all the sprites casting a shadow. I'm wondering if that could be done for GNW core as well?

I think that might be possible.

Game Boy renders in a square pixel grid, hence the particular mask filter producing that "drop shadow" effect has been possible (that's why it requires both horizontal and vertical integer scaling for it to work).

I highly doubt something similar can be tailored to the GnW core from a computation budget standpoint (no "pixels" per se here), but hey, with MiSTer genius devs, I've learned to never say never

I certainly believe one day it may be in-game.

Wish I could have learned to program, I'd love to work on some unloved systems myself and bring them to the MiSTer, but I sucked a programming classes and self-taught never got me very far, always had questions and nobody to answer them.

Update 3: vector graphics, heard of them, never worked with them. Not sure if shadows of a lighter color could be added to the SVG file directly.

It's easy to edit SVG graphics in Inkscape, and adding a drop shadow is simple.
I did some tinkering and found that it looks great, but the core does not show the shadows once compiled. I think the rom file is looking for specific elements in the SVG and adding the drop shadow layer breaks it.

Sounds like you're close. Hopefully there's a solution.

I was able to get it to display shadows in MiSTer after compiling, but it looks terrible. There is pixel corruption everywhere.
Also, the LCD shadows being in front of the background png completely spoils the effect.

We will have to be satisfied with only the background png containing shadows, not the lcd graphics in the svg file. The core would need to be updated to handle this stuff, possibly the rom files too.

Thank you to all for adding GnW to MiSTer! Now I think if the MiSTer Handheld gets released, i doubt ill wanna play any other core then! lol

[scrdcow]

I also really love the core! Not sure about any limitations. But it would be neat with a border/frame on/off option. So you can choose to show the full unit if you want.

Hello, could you please suggest me some good INI Settings with VGA Scaler to output G&W on my CRT?

[eLLuiGi]

You need first the beta vga output core available on discord

Has anyone configured the original two screen Donkey Kong to work on this core ?

Many thanks.

I can't seem to figure this core out. When I load up any game, it just shows all sprites on screen, kind of like when you pop a new battery into the real thing. I cannot get past this, no matter what button I press on the keyboard.

'A' button should start game A and 'B' button game B, once you've mapped the buttons in the 'Define GameNWatch buttons' section.

MANY MANY THANKS !

Honestly - really apprichated and happy as a pig in poo playing this !

I think this only works when using a USB controller. Mapping the buttons to the keyboard doesn't work for me.

Damn this plays soo well.

I play a few games in this video, not just Donkey Kong - but some of these are bloody hard...

Yeah you're right, sorry about that.
It lets you define the buttons but cant get the KB to behave as controller 1. I Couldnt get the 'KBD TOGGLE' feature working.

Has anyone had any luck getting other non G&W LCD games built and working with the core?

[breiztiger]

hi no one to complet this great core (SM5A for Octopus ...) ?

[LamerDeluxe]

I hope Pierco will find some time again at some point to continue development on it, as it is a really cool core.

[Jegriva]

Hi,

I am using a CRT via RGB Scart, what .ini settings should I use to play the G&W?

[hitm4n]

+1 on this. My sister and I had Octopus and Parachute back in 1981 i think. Mine was Octopus and after playing all the others i still think its one of the best. 2 screen Donkey Kong is brilliant though, and Marios Cement Factory, Mario Bros.... Hell they're all great

[Newsdee]

I'd love to see Super Mario Bros and the Zelda G&W games on this core... although no idea what kind of hardware it would need on top of what already exists

[LamerDeluxe]

This new alternative Game and Watch core is really good, nice resolution and it currently supports more games: https://github.com/agg23/fpga-gameandwatch

There's a recent pack for it at the archive.

[LamerDeluxe]

It really looks fantastic on my iPad display. I'm currently discussing options to reduce the black borders with horizontal double-screen and single screen games with the developer.

it's a great core, i love the double screens, you're right about the borders though..

[LamerDeluxe]

I've suggested a resolution of 720 x 540 instead of 720 x 720 for the single-screen and horizontal dual-screen games. That should allow the scaler to fully scale up to a 4:3 display aspect ratio.

Hopefully syncing to the MiSTer clock, LCD shadows and high score saving could be added at some point. Bezels showing the handhelds themselves would be great as well.
