mame2003-plus: hundreds of new games, improved input, features, new bugs - now with runahead support

Well it was Luca Elia who fixed this issue, i just backported the code into this core, kinda like copying the guy next to ya at school :) but still it's another happy ending at least.

@arcadez2003 You made me remember this quote from http://blog.wolfire.com:

We have opensource facial hair: if one guy has a big beard we all copy his code and get our own beards.

Thanks a lot all for your help last week :)
Now i have my full set MAME 2003 Plus <3
I began to try some games and your work is so fantastic :)

But i have one question for CHD games ...
Mine are CHD2 not v5, but i think it help because less compressed.
I try to use them on USB drive or directly on the MicroSD car.
I try Area51 and KI1 KI2 and all are slow, impossible to play them fine :(
On PI 3b+ ... is it normal ? Is there a trick to help ?
Because i remember on XBOX @arcadez2003 we can play KI1 and 2 without CHD and not with MAME, but at full speed on a low 700Mhz proc with 64Mo of RAM ... :(
Why not on PI who is a 4 core, 1400Mhz with 1Go of RAM !!?
Thanks

Most of the CHD games tend to big chunky 3D games which the xbox and many platforms that use this core will always struggle with, not being a fan of 1 vs 1
fighters preferring the ole scrolling beat em ups, i never bothered with the Killer Instinct games so im not 100% on this but im sure the xbox has a special
standalone emulator port which is heavily optimized for low spec hardware hence you could play em on a stock xbox.

SPPV is the current custodian of that project, maybe if you ask him nicely he might look at porting it across to the RA platforms sometime.

Right here's the thing "watching what i say here as the subject matter is adult in nature", after reading a story about big hairy beardy men who all lived in a house
together as pups and they all had a master who wanted them to inject a certain part of their anatomy with a substance which made said part of their anatomy grow
to a huge size so they could rub their faces against them kinda makes me prefer my copying your schoolmate analogy instead :)

Post Script

One of the pups died after the injection hence it made the newspapers and me hearing about a whole world i never knew existed :)

Me too i prefer Street of Rages, and CPS games ;)
But it's a CULT GAME, important in the Video Game history and it's why i wish found a solution to play with it.

Like i write i also try AREA 51, a fantastic shooting game !!!
I love it, and it is really slow too :(
Don't you have try it too ?

but im sure the xbox has a special ...

I don't use it from many years :p
The pi is life for me now ;)

Maybe, i can try ... but xbox gamers are always on xbox lol
They really evolve from many years ...

3D arcade games are generally impossible to run at full speed on current SBCs without a dedicated emulator, their original cpu+gpu put too much stress on the SBC's cpu, generally you'll need a dynarec to lower cpu usage, a 3D renderer to offload video processing, or both.

I doubt you'll ever see a dedicated emulator for arcade games based on jaguar, and while it might be possible to add this support to virtualjaguar, i doubt you'll find any developper interested in this (not that it would run full speed on a rpi3 anyway).

@arcadez2003 Thanks Luca Elia, for letting arcadez copy your homework!

I added support for Lethal Enforcers a while back however there was still a little bug with the background scrolling in the section with the cars on mission 1,
this also affected the highscore table minor stuff really but annoying none the less, anyway the fix to sort this was on the large side and touched a fair bit
of the code connected to all the 16 and 32bit Konami games.

But today while researching this issue i found a little hack by robiza which didn't make the MAME WIP, i guess it was done before he fixed things up proper like
this is good in the sense it was a simple addition to this core which saved me a ton of work and does not affect any of the other Konami games which means
i didn't have to test em all :)

The shops not scrolling correctly on mission 1 is now fixed, and for good measure i've went ahead and silenced some debug code which would throw out
an "unknown pri" popup message at various points in the game, so all in all a couple easy to add fixes make Lethal Enforcers look a lot sweeter in MAME2003+

A few bits n bobs............

Added the missing inputs for button 3 for Bonanza Bros

Fixed the music and sfx cutting out level 2 onwards in Super Spacefortress Macross II.

Attempted to get Scramble Spirits to work, please test it " using the latest rom from MAME" and lemmie know either way if it's playable now.

Riverstorm

@arcadez2003 - Thanks for the updates! I tested Scramble Spirits (sspirits.zip) from MAME 0.215. It starts to load fine and you see:

Sega
System-24
Now Loading...

after that it goes black though I can pull up the TAB menu, dip switch settings and exit the game, etc.

Thanks for trying it out i was hoping all it needed was the correct inputs and a better dump of the disc image, however it's likely gonna be
the big changes to the memory map handling in the system24 driver circa MAME79 which got the game working, too much graft
required to backport those changes to this core so Scramble Spirits will have to remain on the non working list.

Ya win some lose some :)

The exact same happens with Gain Ground, another Sega System 24 game. Is it the exact same issue?

Nope different problem as Crackdown, Gain Ground and a few other Sega System 24 games are protected via the Sega FD encryption that's why they dont boot,
this core would need an updated MAME90 version of the M68k cpu which supports decryption routines for these games so they would work.

Alternatively i've seen websites that boast of decrypting the Sega System 24 games so they run on a standard M68k rather than Sega's FD M68k variant
from what i can tell these are kits to use for arcade machine collectors and dont seem to be available as romsets for use in MAME like you get with the
Sega 16 / 18 games, this is a pity as our M68k CPU would have been fine for running a System24 game which has had the protection ripped out
it would have been interesting to see if they would have worked with our ole MAME2003+ System 24 driver.

A wee while back a super rare game on alotta MAME veterans wish list after a few false dawns was finally secured and dumped, however it was a conversion kit on Pacman
hardware rather than the proper dedicated Epos version, this created a problem for me as to get it up and running they had to rework more or less all the pacman
machine emulation code.

Sifting through 1000's of lines of code changes looking to pin down the parts required to get the game up and running in this core wasn't something i was gonna
ever do but as luck would have it another version of this game turned up on the proper hardware and well it dropped into our ancient Epos driver with no trouble
whatsoever.

Being a spooky haunted house deal i wanted to drop this on Halloween but the colour prom needed a redump and then i was busy with other stuff, so better late than never
here's a new game ya's can play or not :)

Eeekk!

You can check my original commit for something that might interest ya's ;)

@Darksavior has Ninja Baseball Bat Man improved at all? I find it pretty terrible on FBA using the latest version of Retropie.

Do you mean FBNeo ? I don't think there should be speed issues with irem m92 on a rpi3b+, but if there are you can try setting frameskip to 1 and/or underclocking the cpu in core options (no restart required, you can tinker with settings until you find it playable).

sirhenrythe5th

just for interest: Ninja Baseball Bat Man runs great using AdvanceMame.

Because of that i cannot talk about the performance of this game with FBNeo.
I use this Emulator for other games that run much better on FBNeo, i.e. "DoDonPachi II: Beestorm" ;)

arcadez2003

Some of the Irem M92 M107 games Ninja Baseball Batman being one use nifty graphical effects which fire on a raster irq line, it's these effects which can cause the games to
have performance issues on some of the lesser spec platforms like the Rpi, you can however disable said raster effects in the driver code and it'll speed the games up no end
but with the downside that some of em will have graphical niggles as a result, from memory im sure the shmupmame builds have done this.

Maybe that's why the games perform better in advancemame builds on the Rpi due the dev's turning off the raster update on the graphics.?? i'd need to check the
source code or see a short vid of someone playing Ninja Baseball Batman "the intro map before the first level starts" to know for sure.

BTW quite a few of the Irem games have speedhacks in the older MAME cores hence why some people might favor using em over FBN, Unfortunately Ninja Baseball Batman
is one the games they did not add a speedup for, which is a real pity as it so obviously could have done with a little kick in that dept.
