I've added a bunch more pictures to the 'MAME 2025' page mamedev.emulab.it/haze/2025-ti... This only really scratches the surface of things that have been done, as many of the more obscure things are difficult to cover. Not everything shown is playable as it's meant to represent progress.

So Atari's Jammin' prototype has been recovered from VAX tape backups by SynaMax, Dutchman2000. I've hooked it up in MAME, it runs on some kind of Donkey Kong kit hardware with extra YM2151.

Some different 666-in-1 NES/VT bootleg consoles were dumped.
The G6 only has Chinese/English
The G7 has Spanish/Chinese/English
The G9 (previously dumped) has Spanic/Chinese/English/Russian.
The G6/G7 also show G6/G7 in the menu background, didn't notice that before.

One thing I didn't realise when the first of these Tou ma Pet devices was dumped is there are different versions of them (different OK-xxx codes, different case stiles) which presumably have different software. Here are 3 of them.

The Wiii3 was dumped, although I don't have proper controls hooked up yet (this is one of those where the code to read the controls is messy and is going to take a bit of figuring out)

Another high effort XaviX game was Champiyon Pinball from Tomy

This again has some nice music with Ramacat's fixes, and I hadn't previously uploaded gameplay footage, only attract demo.

Another pair of XaviX highlights are the very obviously Sonic inspired Super Dash Ball and Gururin World, both from Epoch

Super Dash Ball uses trackball controllers, Gururin World is a tiny unicycle.
Sound is improved in both.

..and if you play only one XaviX based game, make sure it's Geigeki Go Go Shooting. This shmup doesn't deserve to be a plug and play exclusive. Satoshi Fujishima formerly of Compile was involved in the development. The new sound emulation does it justice. www.youtube.com/watch?v=PRAL...

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)

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.

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....

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.

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.

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.

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)

You might think it's pointless documenting some of these crappy handhelds, but talking to people who work in retail, where some of them get sold as 'impulse' purchases near checkouts etc. they must be flying off the shelves, likely outselling some modern commercial games. They're relevant.
