Home Page Forums MAME MAME TMS-09xx/1xxx thread (was New Dumps)

https://github.com/mamedev/mame/pull/10264 needs proper inputs (I don't play Mahjong so I don't know what I'm looking for, currently just set to a bunch of switches you can toggle for debug)

I have the same thing here locally. ;o;
It's such an easy driver so I don't blame you for not saying you take dibs (also since I haven't said anything either).

I don't know where you're getting the 8000hz beeper from, copied from the other source code? Be mindful of the original copyright holder and GPL2 license.
It's a 1bit dac, directly controlled with d0.

Z80 is indeed 11.0592_MHz_XTAL / 4, and it matches the sound pitch here:

It is apparently from 1982.
I couldn't find other metadata, like which company manufactured it.

Here's my one: https://pastebin.com/153QVK6s
Looks like we both chose to use the tilemap system.

Well I tend to use 8000hz as a default as it's a common value in sound systems (this is also what the Monon DAC timer is hardcoded to right now for example) and assumed it was a beeper rather than proper DAC

I don't mind which driver you use, I knocked it together in about half an hour, I thought it was kinda obvious I was going to look at it when I said it was simple and made the comment about the rom loading (4 program ROMs is correct, 1 combined one is not)

Alright, well, change it to 1bit DAC.
"マイコン麻雀" is "Micom Mahjong" (transliterate, don't translate) - probably change filename too, which in your PR has an error (mame.lst and filename itself don't match)

And the 16 in your gfxdecode means 16 colors? It has 1.

I've just changed it to use your driver with the correctly split ROMs based on the information that was provided

Just in case you both haven't seen it, here is the blog with the photos of the system and list of parts, etc.:

Got it.
It also more or less confirms that the rom labels are ok. Since it's 1,2,3,4,[0x4000-0x4fff empty], and it happens to be an unpopulated pcb spot.

Whoa!!! You guys have already a driver working ? That was fast!!!

slmzy39 posted the link to my blog before i could, that's all the information concerning this game console i could find in 15 years of research.
And if you need the original eproms dumps (without renaming and/or merging), you can get them here:

Wish i could help more but i'm NO programmer, best to leave it to experts like you guys!

Thanks hap for the info, so until someone finds the proper information to emulate the chip, it's "on hold"....just curious, how many VFD games are dumped but can't
be emulated due to missing information ?

Dumped but not emulated?
See a couple of forum posts back about games that don't have an SVG screen yet.

*edit* Oh, maybe you misunderstood?
Astro Thunder is not dumped.
