Makes me wonder if there will be Tate mode.

That looks absolutely fantastic! Really looking forward to trying this version.
Next up: MiSTer piezo speaker add-on

Another update for the Game & Watch core.




If you wish to help with testing the latest release of the Game & Watch core a pre-compiled RBF is available if you are a subscriber of Pierco's Patreon.

If you wish to compile and test the core yourself, Pierco has also pushed latest sources to the Game & Watch repository.

Absolutely loving the fast progress on this core. It almost looks as though it was filmed from an actual G&W display.

EDIT: I built the core, but I don't have bin files for it (the old dkjr.bin doesn't work on this version). I've been mucking around with the generator.html a bit, using MAME G&W ROMs and artwork. I have no idea which value to put in the time location parameter. Button settings would be trial and error.

The only thing I've achieved so far is a bin with the background being displayed with white LCD images that only remove the background.

EDIT 2:
Oh cool, now I'm getting proper black LCD graphics somehow. Seems like you might have to use bkg2 instead of 1. Game is not working though, probably because of the time location parameter.

EDIT 3:
Awesome! I got DKjr working! Buttons are incorrect, as expected. Time location parameter is the default 14 value.
Using BG2 and SVG1.

EDIT 4:
Got the correct buttons now, there's a bit of logic to them, if you realize that it is a matrix. Man this new core looks fantastic. Audio clearly still needs fixing.

Another update for this core has been pushed to GitHUb.

That is great, I was going to ask if that was possible and here it is already. Adding up-scaling filters already helped a bit.

I was able to convert some dual-screen games as well. The tool is not difficult to use once you get the hang of it. The only problem I have is that some games show white LCD graphics instead of black, for some reason.

EDIT: I converted Snoopy Tennis with the updated tool, it looks amazing, I don't see any pixels anymore. Also, it seems like the white LCD graphics problem is gone now.

EDIT 2: I'm getting a mix of black and white LCD graphics (with what looks like anti-aliasing pixels around them) with Mario Bros. Could be my source files.

EDIT 3: This also happens with games that converted correctly with the previous version, like Donkey Kong Jr., Donkey Kong 1 and 2. Mario Bros and Life Boat are also affected. The artifacts seem to be graphics that are triggered at the wrong time and look like only anti-aliasing pixels.

This is the first time I'm trying to compile a core. I'm getting a few errors. Can anyone help me out?

Same thing happened to me. I'll wait until it's release. Looking forward to this.

Okay, maybe it's the wrong version of Quartus... I'm re-downloading an try again.

I'm using 17.0.2

Hi LamerDeluxe!

I succumb to my inability to understand the use of tool. Here's what I'm trying with, Tropical Fish:


In this picture, I've already uploaded the (single) .svg from the MAME set on top of the background.png, but it won't show either as a preview, nor it would display when I load the exported .bin in the core. Not to mention the control settings (K1-K4 x S1-S6); I mean I get they represent a matrix, but in this particular example, there 're only two buttons directions: left and right

Could you please post an explanation of how you figured it out in layman's terms?

[edit] Hmm, I think I can see now as far as inputs are concerned; S1-S6 correspond to the number of available buttons, and K1-K4 correspond to the positioning of the LCD segments, right? err... no? Oh, it's the other way round, isn't it?

It's working fine with 17.0.0

If you are using Firefox, it doesn't work correctly with it, for some reason, giving this exact problem. I had problems with hanging scaling buttons in Chrome, right now the best bet is using Edge. Fuzz discovered all of that.

The correct button assignments can be looked up in the MAME G&W sourcecode: https://github.com/mamedev/mame/blob/ma ... _sm510.cpp
Search for the section of a game in the code, use the order the controls are set there, in reading order in the converter tool UI (left to right then up to down). Often occurring is 'time, game b, game a, alarm', in that order. Buttons are often named slightly differently in the code.

Right now there are problems with anti-aliasing pixels showing in the wrong places, with some of the games. To turn off anti-aliasing use 0 as the mask expansion setting.

For dual-screen games, use bg1 and bg2 plus svg1 and svg2, scale and place them by hand. It would be handy to have options to scale and place them with dedicated buttons (and then finetune by hand).

Analog video out?

I didn't get a signal out of it.

Oh Wow! Can't wait for this release! The MisTer community is amazing!

Thanks to your clear instructions, I've managed to convert every SM510 MCU game that's currently supported by the core!

You're right; quite some patience is needed to scale layers correctly, and the AA mask indeed produces artifacts on screen. I think using a median interpolation filter alleviates that problem.

I wish I'd be free to share the fruits of my labor here, but I don't want to be banned
NB: This is the core you want to assess input lag; try Oil Panic

Great to hear that! I was also able to convert all supported games. Scaling correctly takes time, though the real games weren't that precise either.

I don't know how AA is currently done, I'd personally just use supersampling. Not sure why the wrong graphics would get drawn with only AA pixels. The games that work well with AA look amazing though.

Today: update to the core but sadly black screen for me (HDMI).

I know and I got them before getting a black eye screen.

I don't know what happened:
After this test I loaded other cores to see if it was not a MISTer problem where sometimes the screen get screwed (although it does not seems to happen any longer), tried again still with no luck. I still had a very old GnW in my Unofficial folder just to see, it gave me a very colorful messed up screen (no surprise), went back to the latest release and now the roms display properly. I no point did I reboot MISTer. Go figure!

This core is fantastic, thanks so much.

It's great fun to play Tropical Fish. I'd love if someone could build Octopus, which is another of my favourites.

Great News! I was really looking forward to this release.

Great news! Many thanks for this new fantastic core!

Thanks so much to pierco for this release!

I'm having some visual glitches in the DKjr screen, where the borders of some sprites are activated by a different sprite. Is that a problem with the .bin file?

It is a problem with the anti-aliasing functionality. When converting a game yourself, set the mask expansion value of the generator tool to zero to remove the anti-aliasing.

I've just submitted a pull request for the readme file, explaining how to convert games yourself.

Nice, thanks!

only those 10 games are supported by now? Or can I get more roms from mame romset?
