Over the last few days I’ve been looking at a variant of the Seibu protection, the ‘333’ MCU used by the later re-releases.
While the Raiden re-release on this hardware is infamous for the terrible sound hardware (a single M6295) and basically seems like an official bootleg the other game that was re-released, Zero Team, didn’t suffer such a terrible fate.
There are 2 versions of Zero Team on the revised platform, New Zero Team and Zero Team 2000. New Zero Team has the first and 3rd levels swapped for no good reason, Zero Team 2000 has the level order restored and an EEPROM that saves high scores.
The V33 platform protection actually turned out to be weaker than the regular cop protection, with many features moved from being part of the COP to being done by the main CPU, including, most importantly, the hitbox protection.
The regular Zero Team has issues with collision detection due to imperfect emulation of the hitbox protection (done by the COP) as New Zero Team and Zero Team 2000 lack this protection they actually now appear to function correctly.
In the end Olivier Galibert identified the protection on these, it’s mostly just angle calculations (a small fraction of what the original COP could do) and with his implementation of that, and my general work on the driver I think we can declare these clones as working.
I’ll cover the Raiden game later, there are some interesting talking points.
Amazing !!!! MAME0.155 is a magnificent version !!
ok now give us ‘EX4’
just curious if this could give us an insight into how things work on COP2-X…
I agreed with that.
Thanks Haze and Devs.
Just compiled, Zero team 2000 works well, thanks Haze. Any chance of getting the missing obj2.725 from r2dx_v33.zip on a.b.e.m.?. Cheers.
Thanks Haze / OG / Kale !
Awesome work! keep it up :)
It’s amazing – someone always makes a demand for more. Is wasn’t even an ask it was a demand. Instead of saying “thank you” or “nice job” it’s “gimme gimme gimme”. No wonder why the DEVs get annoyed so easily. Now I see why.
Good to see new Arcade Machines ported for MAME!!!
When we will see Prohibition on MAME?
That’s a good question to ask I think.
sur une pcb que je possède le circuit cop2x je l’ais dessoudé et mis sur un support .quand je retire ce circuit ma pcb est fonctionel est ce normal?

Finally the wait is over, Thanks Haze to this magnific work, you made my day! awesome!
With the actual release, Raiden II new only has graphics and lots colors incorrects
Only crossing the fingers for fix (in this year) Seibu cup soccer and the leggionaire driver games
This is awe awe awesome!!!! >_< seriously i'm can't speak this this is amazing work on mame unbelieveble!!!
this means get my dollar men get my dollar here to you dev!!!!!
Thank you for your efforts and pay!
you seem confused about what emulation is…
Guys am I missing something here – I’m using MAME 0.154ex3 and I can’t get Zero Team 2000 to work. I get a ‘This game has no sound’ message before the game starts, I press 5 to add a credit and hear the ‘coin’ noise but then the screen goes black and nothing happens. If I just leave the game on the attract screen as soon as the game logo disappears the same thing happens and the screen goes black. Is there a newer version as someone before mentioned MAME0.155 ??
Thanks in advance and thanks to Haze & devs for all their hard work :)
nice job Haze !!!
Thanks also to OG and Kale for raiden 2 & raiden DX improvements…Waiting to see your help for FBA port…
ex3 was released before the Zero Team 2000 progress
if you compile your own build from current SVN code you’ll have the progress, some other people do this, but I’m not going to link / recommend such builds as often they are badly compiled or contain other undisclosed hacks that might impact how well they work
best option is to wait for an official 0.155 (no idea when that will be released) or an ex4 build, which I might post after giving the game a full run through, looking for missing blending etc. It’s possible there will be other improvements by that point too. Just keep your eyes peeled!
What a surprise !!!!!! New Zero Team playable :)
As always thanks for your effort Haze.
I have this game on the original PCB.
Not if you may have noticed but the screen does not display complete. The bottom of the screen is cut off.
I am attaching a video I made long ago for youtube.

Good job!!!
join object roms 2+4 from a regular Raiden DX
ok, thanks, I’ve fixed the resolution
wow! this is a nice update! thx Haze and Devs!
Haze, thank you for fixed the resolution.
Now, I´m very happy.
Regards.
thx for the tip.
Thank you.
Just curious as to how the Zero Team games in the
raiden2 driver perform currantly as i seen two commits
related to game collisions on the SVN
Reason i ask is one of the commits said collision fixing
i wondered if that meant the hitbox has been improved
now in those versions of ZT
apparently not yet perfect, still use some commands that aren’t 100% understood.
Haze, thank you for fixed the resolution.
Now, I´m very happy.
Regards.
How strange this people is obssesed about “demanding” words…
Do you realize what game you need to get fixed and is still not done yet for you?
Let’s calculate the desired people.
They are humans with feelings, not monsters from other planet…
Hopefully nmk games are now sound. Oh, about “Zero Team” i never figured was “inspired” in “The A Team” TV series, mmm… that black van whit small red lines across beginning stage 1…
zeroteam is still missing alpha table for ‘1st boss spear shadow’
