Game & Watch Core

[LamerDeluxe]

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

On the Github page, there is a link to the ROMs.
https://github.com/MiSTer-devel/GnW_MiSTer

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

Only games that use a SM-510 MCU can be converted at the moment. You can use ROMs and artwork from the MAME G&W rom set. I'm working on adding readme information to the repository, explaining how to create bin files using the generator tool.

Hi to all,
same issue here via HDMI. I run the core and load bin files I got from the torrent but I get just blank screens (except for Tropical fish and Turtle bridge, but games does not start anyway).

Massive thank you to Pierco for this and indeed Tonton for getting a few ROMs compiled too...

While not exactly a direction I ever expected Mister to take, I'm still very impressed by the results.

@ vitopod
As I mentioned it later on it all started to work, I did not even restart my MISTer. Today I just started my MISTer, started the core and all roms load fine.

Dumb question... I cannot seem to get the right directory name to put the Roms in... I've tried "GnW", "Game&Watch" and "GameWatch"...

Could not find this info in the GitHub page...

Any pointers here? Thanks in advance.

The folder has to be named "Game & Watch".

When in a core menu look on the left side in the vertical white band: it is the name to use. Exception Minimig -> Amiga.

Here's all the CPU cores for G&W and the number of games supported:
-ATmega169PV: 1 game
-SM510: 18 games
-SM511: 23 games
-SM512: 4 games
-SM5A: 15 games

Currently, the SM510 is the only one of these CPUs implemented. 10 ROMs have been created for this core. However, 8 haven't been done yet. Here's instructions on how to generate the ROMs: https://github.com/MiSTer-devel/GnW_MiS ... 4da4d14578, and these are the missing games:
-Crab Grab
-Donkey Kong
-Lifeboat
-Manhole
-Mario Bros.
-Mickey & Donald
-Rain Shower
-Spitball Sparky

This page on MAME's GitHub was one of my resources: https://github.com/mamedev/mame/blob/ma ... _sm510.cpp and it lists the R-Zone as a "child driver" of the Sharp SM5xx family of handhelds. Does this mean that this core could eventually support R-Zone games? Also, the Electronika IM-26 is a Russian bootleg hardware clone of the Game & Watch so those games could eventually be supported as well

Electronica handhelds run on complete clones of Sharp CPUs and I believe they have identical roms to Game & Watch originals, so I assume they should already work with SM510 roms when supplied with Soviet graphics.
There was however one unique Electronica game called Автослалом (Autoslalom) which had no Japanese original, but that game runs on a clone of SM5A CPU.

If anybody's looking for the missing SM510 games, search for "Game & Watch MiSTer FPGA" in the archive

Ace, thanks for doing those!

Looks like the remaining ones are:
-Crab Grab (doesn't seem to be artwork for this one, and is tall screen)
-Rain Shower (tall screen)
-Spitball Sparky (2 screens side by side)

A assuming these different screen layouts aren't supported yet, you can see the artwork for the games here:

I converted Rain Shower for an older version of the core, it worked fine. Spitball Sparky converted fine as well, but uses color tricks that can't currently be replicated on the core. Same thing with Crab Grab, I did find artwork for it.
EDIT: Turns out my Rain Shower conversion still works with the current version of the core.

Just to confirm: Game&Watch Core doesn't work on CRT via analog I/O, isn't?

[wark91]

Yes it is not working. It needs some updates to make it works

Happy to see this getting released. I experienced some graphical glitches in Donkey Kong Jr, like weird noisy ghosting effects. But that might be a problem with the ROM rather than the core.

This is caused by the anti-aliasing functionality. It can be turned off for now, when converting a game, by using a mask expansion value of zero.

As a test with non-Nintendo games, I've just converted Konami Top Gun and it works. Not sure what the time location parameter does, but it didn't have to be changed.

Confirmed with Konami - Double Dribble (handheld)

So Cool!! Thank you for testing the non-Nintendo games! I will have to update the readme

I'm currently working on the anti-aliasing problem with double-screen games. I need to rewrite a part of the generator but it will have no impact on the binary files so old generated games will remain compatible.

That is great news! Really looking forward to that update.

Is there a way to have independent controls on the Dual Screen Mario Bros Game. I had it as a child and each side had an independent Up down for the character. On the current version up/ down moves both brothers which makes the game much harder if not impossible as it was designed so that each brothers can be moved independently

[Pierco]

Yes, it is possible but I need to add more buttons on the FPGA side so we can map them in the generator. Currently only have left/down/up/right/A/B/Jump. I will open a GitHub issue about it.

See the post by MMarino4 in this Reddit thread for information about updated more complete background artwork.

Thanks for the update, moving the Loading of BIN to the top row is a really nice touch.
I renamed the games sudirectory updated MISTer, started the new core, loaded a BIN and ... the gremlins came back: black screen.
This time I went directly to what fixed the 1st time: I started the very old core, got a colorful messed up screen, started the new core, loaded a BIN and I got the display back.
I will delete all config files related to this core (may be something dating from the prehistoric core is making trouble with the config). I will see what happens on the next release.

both packs only provide 15 out of 18 between them unfortunately.

I wasn't able to convert Rain Shower unfortunately; the .svg's included in the MAME romset came out blank in the tool.

As for the other two omitted, those use a weird display format, sorry

The core is only going to improve from now on, so I guess we'll have to redo the conversions anyway

didnt realise this was your stuff, thanks for the ones you have done!

The Rainshower svg has the IDs reversed for the two layers. Open in notepad++ and find id=layer1 and id=layer2 and change them to the opposite.

Great find, thank you

As for the anti-aliasing bug with dual screen games, I suggest using:

Code: Select all

[GameNWatch]
vscale_mode=1

...in the .ini, and Interpolation (medium) as a filter for now.

Does Manhole work for anyone? All other games work for me but Manhole won't start for some reason. It loads the bin file and I see all the graphics but when I press the buttons on my controller the game won't start. Just wondering if I'm the only one with this problem
