I've just been reading about the Bandai Playdia. It was released in Japan in 1994 and reminds me of the Casio Loopy from 1995. Both are were for kids, and both have great content for girls.

Is anyone aware of a driver being worked on for this or of an emulator elsewhere?

Here is a video on the Playdia:

We know about it. I don't know what's known about the internals though.

There's a PR open with some CD dumps: https://github.com/mamedev/mame/pull/3189 , but without a driver it doesn't make much sense to merge it.

Here's a PCB pic (credit: incog): https://imgur.com/a/1LO1QKo

According to Robbbert there are at least 2 chips with internal ROM:

uPD78214GC = CPU with 16K of ROM and 512 bytes of RAM, various i/o, uart, timers, etc

TMP87C800F = CPU with 8k ROM and 256 bytes of RAM, various i/o, timers, etc

We emulate both of those CPU architectures, if not those specific chips (78K-2 and TLCS-870). Presumably at least whichever is the main CPU could be trojaned, but I'm not volunteering :-)

I'm not sure there's any external code on the disc, unless I'm thinking of a different platform, so trojans might be more difficult than you'd think.

I just went on Ebay to see if I could buy one to send to whoever wants to trojan it, but it's far more expensive than I thought. I just wasn't expecting it to be a collector's item... I thought the system wasn't supposed to be very fun.

Neither was the Philips CD-i, but prices are through the roof on players there, too. The retro market's pricing is sadly extortionate these days.

Everything is a collectors item these days unfortunately, prices have skyrocketed during the last couple of years and show no signs of dropping back.

Ebay is not a good place to buy something like rhis thjough, you'll find much better deals on Japanese auction sites like yahoo, rakuten, etc.

here's a message to those "collectors" who just sell their shit for "money": STOP CHARGING HIGHER PRICES!!! THEY'RE ALL INACCESSIBLE!!! VALUE DOES NOT EQUAL MONEY!!! NO ONE CARES IF YOU NEED MONEY!!! GO HOME AND TAKE YOUR GREED WITH YOU NOT SPREAD IT TO OTHERS LIKE IT'S SOME SORT OF VIRUS!!!

Same price hikes as we're now seeing for a lot of the 'crap' we picked up when I was buying random bits and pieces.

I'm glad we picked up what we could while it was still available for cheap as I hate to think of the struggle we'd be facing if we'd waited another 10 years.

People charge high prices because collectors actually pay those prices, otherwise they wouldn't go up. It's simple economy, demand vs offer.

That's true, but unfortunately there's still a lot of stuff that needs to be preserved and with most collectors having a hoarder attitude it's getting harder and harder to get things done unless you have really deep pockets. I think community donation pools towards specific items should probably be the way to go in the future otherwise preservation will struggle.

"simple economy", fuck that shit, just put collectors accountable for their greedy attitude or something.
we don't have to rely on community-made crowdfunding scams effortsso we can "preserve" old hardware that's going to die out anyway, especially at the mercy of these fucking assholes.
the only way to do it soon would be to put them at an uncomfortable position where they have to be selfless so the emulation and preservation scene can thrive.
remind them of their and other countries' economical situation and ask them if pursuing a selfish attitude for the sake of "having everything" is a healthy one in the long turn.
that way, they will be forced to offer cheaper prices with the aim to make them realize that there won't be any one buyer willing to deal with their bullshit.

I've been doing this for near 25 years. At this point I'm at the point I'd rather just see things lost than give in to the ridiculous market demands.

It's not even *fair* to ask for donations at this point, which is why I've refused when people have asked me to do donation drives recently.

Chucked Team Europe something like £100 of my own money, but with all that's going on in the world the last thing I feel comfortable with is asking anybody for money.

I'm with Haze on this.
I gave up collecting arcade boards for MAME a long time ago, fundamentally because of diminishing returns.

Financially, it's not worth it, but your efforts did get boards preserved and into Mame. I donate or buy things when I can just for Mame. I think I'm more interesting now though in handhelds and obscure consoles being preserved than arcade boards.

then you should be more than careful about it.
the retro gaming market is about to get pricier and i'm all in for seeing the consequences of having that market dry up due to all the bullshit that comes with it.
in fact i'm more than looking forward to seeing it happen.
the people involved deserve a lot of scrutiny for their actions.
have their actions bite them back in the ass, to put it in layman's terms.

just like what happened within one week of Elon Musk having full control of twitter.

Nope. Often on eBay I see e.g. moonpriced 1980th home music keyboards rot for over a year without being sold. Beside hoping that an idiot with too much money (or band that immediately needs an intact one because theirs broke) buys them, the real reason often is that outside eBay they then sell other specimen (e.g. in a used goods shop) by only refering to that eBay offer while claiming that it would be the regular price, and selling theirs slightly cheaper but still severely moonpriced. So the customer thinks that a Casio VL-1 for 150€ from a local vendor would have been a bargain, after being shown one for 600€ on eBay and the scammer reduces his one from "only" 400€ to 300€ and finally ends at 150. Often they may even produce staged sales on eBay to make eBay record those events to later pretend a proof that they do sell for such a price.

With other collectables there may be people those pay extreme prices (typically singletons or prototypes or objects by manufacturers those later turned into luxury companies), but it takes only 2 fools to bid a price to any height, and nothing proofs that the item regularly sells for that. Hence an Apple 1 prototype for 1 mio € is not really comparable with other stuff.

While most of your conspiracy theories are ridiculous, yeah, that does happen, I've lurked in a few channels where they've been involved in that, getting others to bid on items they have no intention to buy just to drive the prices up etc. too.

The common knowledge that shops will try to match eBay prices is being used to manipulate sales all over the place. All the news about a copy of Mario being "worth" over a million etc. caused a lot of places to increase their own prices 3-4x and still claim you're getting a bargain.

The grading bullshit that's going on should be illegal IMHO, and anybody involved in it, even slightly needs locking up. The prices being thrown around, in no way reflect the value of the game to the regular market, not even a brand new copy frozen in time is worth close to that - the games making the news aren't even rare, it's just artificial market manipulation.

Yeah, I agree with both you and =CO=Windler. It's refreshing for something to be so cut-and-dried terrible that even people who I occasionally disagree with are aligned on the topic.

The ironic thing to me is the claims by collectors - hoarders, really - that emulating a system brings down the value of the physical hardware. Even 10 years ago there was ample evidence that that was a falsehood, and it's only been thrown into sharper relief over the past 5-10 years seeing the extortionate rise in prices the instant MAME even starts to take a sideways look at something.

The reality seems to be that emulating something objectively raises the value of a physical artifact, as the act of emulating it inherently means that more people become aware of it, and inevitably a subset of those people who become aware of it are going to end up having a desire for the physically tangible version of it.

For anyone without non-fatal craniofecal disorder (AKA shit for brains), simple supply/demand economics indicates that if the supply of a product is fixed (which it always is for retro hardware, if not actively decreasing due to hardware failure over time), then increased demand will lead to increased prices. It's such an obvious conclusion that I sometimes wonder if the collectors screeching like an angry sow about emulation devaluing "my preciousssss" aren't instead some hologram conjured up by a vindictive AI running out of a broom closet in Meta's data center.

In addition to grading games just being dumb in general, WATA has also graded Pokemon ROM hacks that someone put on real carts, and printed up fake boxes for. People are trying to sell those for hundreds to thousands now.

oh great, rom hacks are being sold for higher prices now.
oh you mean people are trying to sell it. that means it's going to fail miserably and people are forced to adjust the price of the thing they're selling to something more accessible! read: lower prices. many favor lower prices.
US$5 is acceptable for selling your physical copy of the game or console you accuse emudevs of "ruining" btw. just in case you sellers/collectors are reading this thread. you both are quite the same actually.

Come on, Pokémon Cock Version is an important cultural artefact. It provides a unique window into the minds of teenage boys who, despite knowing nothing about sex, are nonetheless obsessed with it.

You're underestimating how retro market goes these days: it's all random, do you know how much on YAJ last Baruusa no Fukushuu for x68k went?

130'000 JPY

Now you may ask: what the hell is Baruusa no Fukushuu? Well, that's the point.

Wasn’t that Zainsoft’s last game, right before they went out of business? That probably gives it some street cred.

Emulation does not ruin the value of a physical object. In the opposite it may raise the chance that it gets into the hands of genuine collectors, and not of hobbyists those only want e.g. to play their favorite arcade game again and trash the machine into e-waste when it breaks because they have no knowledge or interest in repair to preserve it as a historical artifact. Emulation even may help to prevent the original from wearing out by repeated use. Only sinister minds who intend to cause forced shortage by this in hope to increase value of their own copy may claim that emulation ruins the price (by keeping more original specimen intact), but this argument is pervert.

Returning to the original topic, I must correct R. Belmont: though I did add a uPD78214 disassembler to MAME, the present 78K/II CPU core is nothing more than a skeleton for ROM loading. (The NEC 78K family consists of several related but mostly binary-incompatible microarchitectures with a somewhat confusing history; none of them have been properly emulated yet.)
