@barbudreadmon - That’s great news, thanks! I look forward to how it turns out. I use AdvMAME mainly for vector games. I think the current version has some regression issue(s) and it runs slow with Retropie. This might be an opportunity to drop the core and stick with m3plus & FBNeo for retro gaming.

Especially since AdvMAME isn't an RA core and thus, doesn't benefit from RA's unified interface and configuration. At least that's my main reason to prefer m3plus & fbneo, with no clear preference for one over the other.

the drawing algorythm somehow expect the PAR (pixel aspect ratio) to be 1:1, setting DAR (display aspect ratio) to width:height

Sorry to step in here, but out of curiousity(!): How is a PAR (or SAR) value for a vector based rom, or better to say display width/height information, obtainable? The FBNeo xml structure is AFAIK nearly omitting all valuable information in those regards and with mame.xml datfiles the display/video entry for screen == vector roms have no width/height information, though the orientation of the display (horizontal/vertical) is included. So my assumption so far was that vector games comply to the DAR == 4/3 or 3/4 rule of thumb (see last bullet point in: LAY File Basics - Part I)? Have I missed something, or am i just interpreting your words beyond or wrongly within their scope?

That’s true it’s missing the Libretro benefits and features. Though it is a strong, stable, flexible core that’s matured.

I know some use it as a primary core. Hopefully they figure out the “slowness” issue at some point as it’s one of the more well rounded solid alternatives to play and test with. Backdrops and overlays are solid but in regards to shaders, AdvMAME falls short, it’s hard to beat crt-pi and zfast on these low end boards.

In RetroArch, you can get all those informations by enabling statistics in on-screen display settings

It seems to have been the assumption when writing those drivers in FBNeo too, however the width:height doesn't always match that ratio, meaning you end up with a PAR different from 1:1, which i think is the only PAR making sense for a vector game (width and height of a point should be the same).

Work still continues on with regards to the MAME2003+ core but i wont rabbit on about the new game support or the many
fixes and improvements here as that is what the changelog and the whatsnew build files are for, but i thought it worth a mention
that you can now play three classic Sega games which due to the usual drama and politics will not be supported in the
official MAME releases.

They wont set the heather on fire right enough but if your a fan of the genre or Sega games in general you might wanna give em a whirl...

Head On Channel

Oo Parts

Sega Sonic Bros

Also some of you might be aware a long lost game turned up recently which was meant to be Midway's attempt at creating
a NBA Jam like version of a baseball game, it didn't really pan out and it's release into the Arcades was cancelled
but now you can also play this curio in MAME2003+

Power Up Baseball

Just lemmie know sometime if you think the trackball inputs need some tweaking as per the pitch and batting speeds.

Thanks! Could you elaborate a little about MAME? (just curious)

iirc those rarities were dumped for the sake of preservation but not added to MAME because the group that dumped them forbade it (something along the lines of "if you add those games to MAME, we won't dump anything anymore for you"). those dumps were leaked anonymously some time ago. they were added to HBMAME though so i don't understand the logic.

Clyde

@barbudreadmon Thanks. Whatever the reasons of the dumping group were. As for HBMAME, maybe its developers just did it anyway and the group either didn't care or didn't go through with their announced consequences.

edit: typo corrected (devekopers)

dankcushions

i was curious so did some research: http://forum.arcadecontrols.com/index.php?topic=159689.0 - see haze's (mame dev) reply. i'm not sure how the end result is that it is not within official mame, but it sounds like the dumps had the potential to burn some bridges so for the sake maintaining their japanese contacts, i guess they chose to exclude these (crappy?) games.

ie what @barbudreadmon said :D

arcadez2003

There are two sides to every story so as a "former" member of the dumping union here is my "opinion" :)

The return of Team Jadump several years ago required that the MAME guru the man responsible for dumping 80%
of your favorite arcade games the man who single handily has done more to further the preservation of classic arcade
games than all the rest of us put together needed to be sidelined, This is due in no small part to several members of team
Jadump having an issue personally with him.

Some people myself included consider Team Jadump to be nothing more than a pcb hoarding collective, sure they'll throw
MAME dev the odd bone like say a Japanese version of a game there is already multiple dumps available for or some lame
prototype no one cares about, any good stuff they have will require that the DU, MAME DEV and or general users all have to club
together and raise something like 5K so they will dump it like we seen with Hang-Zo for example.

What MAME and the DU fail to realise is this only helps to fill their pockets and they'll use that money to secure yet another
rare arcade game which disappear into their private collection never to see the light of day again, so in the long run
MAME DEV and the DU are only cutting their own throats here.

And i guess they fail to remember that team Jadump sat on a copy of a rare game called Monkey Magic, they knew the DU
was going to bid big money to try and secure the game and did not inform them they already had a copy of it which could
have been dumped and shared with the DU for free, but no they let the DU waste thousands of pounds securing another
version of that rare game when that money could have been better spent elsewhere not exactly DU friendly behaviour IMO.

HAZE is spinning a yarn sticking to the company line that these games were stolen, certainly there is a leak in Japan otherwise
the Guru would not have obtained the dumps for these super rare prototype Sega C2 games from several different sources,
what he fails to mention however is several members of Team Jadump actually own the pcb's for these games so have a vested
interest when it comes to their inclusion into the official MAME project or not.

Well at least there is the upside that there are now three less games they can charge 5k to emulate :)

Ofcourse his argument around why these games are omitted from MAME kinda falls flat when you consider they support this stolen game............

https://arstechnica.com/gaming/2019/04/after-a-lost-atari-rom-leaks-retro-fans-ask-was-it-stolen/

A clear double standard here then i guess they only bother if the arcade pcbs which belong to "certain" people are released when they shouldn't be :)

Anyway if MAME dev want to bite the hand that constantly fed them for 20 years eg The Guru and side with a bunch of rom hoarders who
only see MAME as some sort of cash cow that can be milked constantly all in the vain hope they might share something half decent with them
down the road and not charge $$$$$$ in the process then that is their choice.

Personally i was always taught to choose your friends very carefully only time will tell if the DU and MAME DEV have made the correct decision.

I know ooparts is a nice variant of breakout, i never tried the 2 others.

It's a decent wee game if you like Arkanoid you'll love this one, it has some boss battles a nifty trick where if you slam your
paddle into the side of the screen it will shudder and shuffle the enemies around and change the pitch of the ball direction
it's got some smart powerups and nice graphical effects here and there you could do alot worse than to give it whirl.

I'll now review the others :)

Unless your a Sonic The Hedgehog fanatic then your not gonna really find too much worth when it comes to playing
Sega Sonic Bros as it's just puzzle dropper more or less, and well the Bust A Move games by Taito really are IMO the pinnacle
of that type of game.

Head On Channel is nothing more than an update to the Head On franchise which sits alongside Counter Run, but unlike those
games it doesn't take itself too seriously and it's chock full of japanese whackyness, so not a bad game not a good game it sits
somewhere in the middle and you'll likely never play it more than a few times.

But whether a game is crap or not the jist of it is a preservation society should seek to use dumps of any game which become
available rather than picking and choosing which ones to support in their project incase they upset certain people who as i've
already stated i think do not have the projects best interests in mind.

There is a divide also when it comes to two Atari prototypes namely Danger Express and Marble Madness II from what i can tell
most people in the DU want to see them emulated where as certain MAME dev's are sticking to a gentlemens agreement struck
years ago with collecters who are not on friendly terms with the project anyhow, and since there will be no future dumps
forthcoming from them there would in a sense be nothing to lose if the romsets are leaked anyway.

From reading my comments people can clearly see where i stand on this, MAME Dev are entitled to their viewpoint as well
the only difference being my "opinions" dont impact on others in the sense im not preventing you all from playing certain games.

HBMAME is maintained by a MAME Dev, Robbbert.

Yeah i know i just thought it sounds daft hence i call em Jadump :) i remember reading that thread years ago my thoughts at the time
being it was something which would further the preservation project, but now i think it was nothing more than a pure propaganda piece
and a big mistake was made by shutting the door on the Guru.

You'll notice anyone who dared to pipe up with an opinion which went against the mutual backslapping on display was quickly jumped on from all sides.
anyway i've nothing more to add really time will tell if the DU and all those MAMEDev's have backed the correct horse.

arcadez2003

MAME2003+ was always about taking the base MAME78 core and backporting new game support plus many fixes and improvements
from later MAME releases, the core sees many new commits everyday but i wanna focus on a couple of noteworthy happenings

Contra

A recent fix was just added where as the bullet and rolling mines now behave correctly on the 3D sections of the game
now rather than simply always ending up on the right of the screen regardless of where your character is they now
correctly target you directly as it would have been the case when playing it back in the day down your local.

It's harder now as a result but no gains without some pains :)

Turbo Out Run

You can now play Turbo Outrun in this core but however since MAME2003+ does not have a M68K CPU which can
decrypt the FD1094 Sega protection, we're hacking around this by making the original MAME78 Turbo Out Run
romsets use some pre-decrypted roms.

As a rule do the following and merge these romsets to create a working version a dat will help you right enough...........

toutrun.zip + toutrund = working
toutrun3.zip + toutrun3d = working

I've already added the Contra fix and another which sorts the missing road layer in Hang-On so it's now playable in
the MAME2003 core, but since those who deem themselves to be in charge of MAME2003 do not want to see the roms
changed then i'll just leave Turbo Out Run in a broken and non working state for that core.

REK607

Hello! Does Mame2003Plus have a 2 players version of Sunset Riders? I am using the 4 players one. I'm considering trying with a child 2 players rom I have for 0.78 if that works

dankcushions

@rek607 you're "considering trying"? why not just try? :)

yes it looks like it's supported: https://github.com/libretro/mame2003-plus-libretro/blob/755e64ed8c7f1fdc5d69e65084a3355c51107937/src/mame2003/frontend_list.h#L1894-L1901

Clyde

The mame2003-plus.xml also lists multiple 2P versions with driver status "good". Just make sure you use the right romset or build one yourself.
