mame2003-plus: hundreds of new games, improved input, features, new bugs - now with runahead support
-
Unfortunately due to code incompatibilities we cannot support the latest Taito C-Chip dumps in this core, but the next best thing is to add a damn good simulation of it
this brings us nicely to Operation Wolf which now has C-Chip sim code in MAME2003+, what does this mean exactly.?? for the unversed the C-Chip is a protection
device that Taito used for certain games in the late 80's but apart from that it also sends commands that handle certain gameplay mechanics.With alotta the games it was minor stuff but Bonze Adventure, Operation Wolf, and Rainbow Islands made extensive use of it to trigger certain level events
the sim code is more or less perfect for Rainbow Islands same with Bonze Adventure although with the latter you sometimes get that respawn error on later
levels, in this core Op Wolf had no sim code until now which meant the following was missing................End of level 2 boss
The enemy has located you random level which can trigger anytime before level 5
The enemy counter keeps track of how many you have killed in each level and will trigger certain events when you hit it, like on level two loads of paratroopers will start
to parachute en masse into the level or on level 4 and 5 the screen will scroll up and you'll have extra helicopters to kill before the level will end.Obviously i'd like to support the proper C-Chip dumps in this core for the above games so they'll be perfect but since it's not possible at least we now have a decent sim for
Op Wolf created by studying the unprotected prototype which means we get lots of extra game content which was missing beforehand.0.176: Bryan McPhail fixed all the Operation Wolf gameplay problems by improving the C-Chip protection simulation. Gameplay should be a true 100% match to original now.
Put extensive notes in the machine file about what has changed. Fixed bug in 68K->C-Chip simulation that could lead to level 2 boss not appearing after first run.0.98u1: Nicola Salmoria fixed crash in Operation Wolf due to improper timer usage.
0.97u1: Bryan McPhail added proper C-Chip emulation to Operation Wolf (machine\opwolf.c). Added 2nd sound channel. Removed Z80 CPU3 and cpu3 rom.

Everything bigman :) seriously so much of the code in the drivers the machine and the UPD7810 CPU from MAME is so not compatible with this ole core i'd rather
jump off a pier than attempt it ha ha, dink tells me to look at how they added it to FBNeo as a guide rather than how it was done in MAME we'll see i guess -
haha i hear you sometimes it better to see the rabbit hole before you go down it matey!

Aye i hear what your saying, but hey the Op Wolf sim is a good one as it was created by firstly checking the reads and writes of the bootleg and then
the unprotected prototype, so it's as good as we're gonna get short of having the proper C-Chip hooked up you'd not notice the difference really. -
Did a little graft on the NMK16 driver fixing up the sound balance in the games that use the NMK004 to drive the music and Sfx, i also fixed up some
graphical problems with level 5 and after you kill a boss in GunNail, as of today MAME2003+ now supports the location test version of GunNail
which is totally different..............https://mamedev.emulab.it/haze/2019/12/31/nailgun/
Proto's or location test versions can be hit or miss in the sense they might only have two working levels or no sound, this one is worth having as it's complete
more or less and plays like a totally different game hence i thought it worth supporting here, you may want to check my comments on the original commit
for additional info. -
Well we've had a good run these past few years with regards to MAME2003+ lots of fixes and improvements backported, a bucketload of new games playable
and many others with emulation improvements, i think the time is right now for me to bring down the curtain finally with regards to active dev on this core.I've enjoyed working on this and all the banter with the guys who helped along the way i hope you've enjoyed using it as much as we did working on it.
Happy new year folks!!!

Well I wish you the best big yean never say never might be another update at some point you created it and done a damn good job. I would appeal for you not to give it up completely you one of the few sane devs i know thats down to earth the choice really is yours though im 100% behind you choice matter what happens the core is in a good place . Happy new year bud. Thats half the problem i was looking at the ost stuff and ended up paying games instead cant help myself sometimes :(.

It's just logically i think we've taken this core as far as it can go. sure i'd like to update and add all the Sega 16, 18, 24, 32, Hangon, Outrun, X and Y-board drivers some real
classic games we're missing which let this core down a little, then there's the Seibuspi games Raiden Fighters and Viper Phase 1, i have the code ready to go for all of these
and more and would love to add it all but my hands are tied by the MAME78 codebase and input handling.So having ran outta stuff to add im snookered more or less :)

@arcadez2003 Dude, thanks for all your work on it. It's almost the only core I use on my cab right now (few exceptions use 2010) and I am very grateful for your wizardry.
-
@arcadez2003 I just registered to thank you (and do some suggestions with encrypted system18 stuff) but it looks like I'll be adding those myself sometime in the future. Thank you again for all the backporting man!
-
How do you know the names for the samples for a game with samples support? I'm trying to set up Teki Paki.
By the way, thank you @arcadez2003 for such a great work. You can be proud, it's an excellent work.

What are your suggestions with regards to Sega System18.??

Usually the samples are named the same as the game rom eg for example dkong for both, Teki Paki is a special case as you wont find the sample on twistys site,
im not sure if we can link to samples on here otherwise i'd just link you to a site that hosts the ThunderMAME Toaplan samples or send it your way myself.Arcade Addict

@arcadez2003 - Thanks for all the hard work you, @grant2258, @markwkidd and others put into this core. It's my main core for arcade gaming with some FBNeo and AdvMAME thrown into the mix also. Hopefully the Libretro folks will keep it running as the RA frontend advances.
You know the fun doesn't have to end. There's always "newer" cores more suited for grafting code, if I remember correctly, that would run excellent on these low powered devices! ;) Nah, so many games and so little time!
But you know whenever someone says they are done there's always one more game, on a lazy afternoon that looks easy enough to throw into the mix! :)
@REK607 - If it helps the current list of games that require samples for m3plus:
armora.zip astrob.zip astrof.zip battles.zip berzerk.zip blockade.zip boothill.zip bosco.zip buckrog.zip carnival.zip circus.zip congo.zip cosmica.zip cosmicg.zip depthch.zip dkong.zip dkongjr.zip elim2.zip fantasy.zip frogs.zip galaga.zip ghox.zip gorf.zip gridlee.zip invaders.zip invinco.zip main.txt mario.zip monsterb.zip natodef.zip panic.zip polepos.zip pulsar.zip qbert.zip rallyx.zip reactor.zip ripoff.zip samples.txt sasuke.zip seawolf.zip sharkatt.zip solarq.zip spacefb.zip spaceod.zip spacewar.zip spacfury.zip starcas.zip starcrus.zip startrek.zip subroc3d.zip sundance.zip tacscan.zip tankbatt.zip targ.zip tekipaki.zip thehand.zip thief.zip turbo.zip vanguard.zip warrior.zip wow.zip xevious.zip zaxxon.zip zektor.zip -
@arcadez2003 that would be great. I have been able to put the sound to work but not fully, it's exiting the game suddenly after a few minutes of playing it.

@REK607 - I'm not sure what platform you running on but with RetroPie 4.5.1 on the Pi 3 Teki Paki runs well. I'm not very good at it but I had no crashes up to around level 20 or so. I played a few games. Any Tetris style game I was just never very good. =/
-
@arcadez2003 Thanks for all your work. This is really an awesome 2003!
-
@Asure i'd be interested to hear back from ya with regards to Sega System 18 and your plans around supporting more games by using the decrypted romsets.
-
@Riverstorm as I see it, my problem is the music is in a very high quality and it's closing the game after a few minutes. I can have sound effects but no music. I run RetroPie 4.5.1 on a Pi 3B. Tetris is a hard game indeed!
