www.youtube.com/watch?v=MEK1... Here's some raw footage of how Hyper NeoGeo 64 will sound in the next MAME release. Some games fare better than others with the recent improvements, with Buriki, Beast Busters, Fatal Fury and Road's Edge improving the most.

MAME avoided it for a while due to the MPEG stuff, but beyond that, lack of interest from anybody capable of implementing it.

a PCB for the Sega / Coreland game '119' turned up. Probably has colour PROMs that still need dumping.

Hardware seems to have roots in Galaxian type designs (sprite RAM looks very Galaxian-like but isn't hooked up yet)

While not identical, the Soccer game in the PDC200 and the Backyard Soccer in the Atari/Hasbro Backyard Baseball+Soccer Plug and Play feel very similar.

David 'MameHaze' Haywood @mamehaze.bsky.social · Aug 5

I've noticed in some of these cheap crappy handhelds the Mega Man 3 pause / selection menu is broken.

David 'MameHaze' Haywood @mamehaze.bsky.social · Aug 1

(it might sound illogical, but MAME tends to be best tested after a release as more eyes are on it, so without a monthly release little regressions, like the SEEPROM issue which broke a bunch of stuff, can creep in unnoticed, so longer cycles tend to result in buggier builds)

David 'MameHaze' Haywood @mamehaze.bsky.social · Aug 1

New MAME is out 0.279 www.mamedev.org?p=553
www.mamedev.org/releases/wha...

Not a huge amount of new working stuff from me in here this time.

A few important bugs with the new sound system were fixed, so worth upgrading from 0.278 as due to the 2 month cycle that wasn't the most stable of builds.

these ones are almost certainly different though, as they're different in ways other than the colour externally, and are different PCBs

No idea if these Punirunes will have the same ROM as each other (or the same ROM as the one you can buy in the UK) as they're all the same generation, but the stripes on the SPI ROMs do seem to have slight tints of the unit colours, so....

ahh, I didn't try reattaching them, that's actually kinda smart, I didn't think it would be able to tell.

David 'MameHaze' Haywood @mamehaze.bsky.social · Jul 30

.. it boots to a Takara splash screen and the menus are in Japanese.

also the plastic stuff is turning into sticky goo, this is disgusting.

David 'MameHaze' Haywood @mamehaze.bsky.social · Jul 30

Takara distributed one of the earlier PDC models (2006 version) in Japan

I expected it to probably just be the same software in a different box but...

I'm also not allowed to disassemble it unless I'm a professional... (we all know I'm going to anyway)

This 'H6' VT based Famiclone really wants to be a Switch. You hade to slide the controllers off to use them. They also require their own power source as a result, which is not great.
Obviously it doesn't really contain 1000 games either.

Twitter is pretty awful, but if they resist doing this it becomes the more functional platform.

It's also the one where I have a more established audience, which is why I've not been able to shut it down completely already.

David 'MameHaze' Haywood @mamehaze.bsky.social · Jul 29

I got an 'F1 game' handheld and an 'F5 game' handheld. Both seem to be running the same software, although I have a feeling this software was originally designed for the F1 unit, which is actually shaped like a car.
Bit disappointing as I thought the F5 would be different.

Since there's now a workaround for the creepy personal data demand on here I've reactivated the account for now.

If the workaround stops working the account will be disabled again, as I don't wish people to think they can chat to me only for those messages to drop into a black hole.

Gotta love it when your parcel tracking gives you jump scares.
Tuesday I got a notification of "Destroyed according to sender's instruction" for one of my parcels from Japan.

Yesterday the parcel arrived just fine. Magically undestroyed, in perfect condition.

David 'MameHaze' Haywood @mamehaze.bsky.social · Jul 22

They're not part of the team, that's independent research, as you'll notice a lot of it is earlier (80s, early 90s) units, as even they can't process the later ones. I'm not aware of them being on Bluesky.

David 'MameHaze' Haywood @mamehaze.bsky.social · Jul 22

I wonder if these K10 handhelds run on different SoCs, Rush'n Attack has raster timings glitches on the blue unit, but not the green one. (also these handhelds don't have a select button, which is problematic, likewise X and A map to A and B, not A and B. Y and B are turbo buttons I think)

and even beyond that, there's no guarantee that even with lab grade skills and tools anything could be done.

there are commercial operations that charge thousands of dollars per hour to look at things like this, it makes the money being spent on these other handhelds look like nothing.

David 'MameHaze' Haywood @mamehaze.bsky.social · Jul 22

In that sense I'm not really sure what you expect us to do. I could buy them, but every single one would simply be destroyed with no result.

If the tools needed to deal with them can't be bought (or don't exist) as they're lab grade, and require lab grade skills it's pointless.
