props to Kale and the Seibu hardware progress

No wip page update, but good to know some Seibu fixes here and there getting a couple more of the Seibu games running. (available for those that can compile own personal build) Likely won't be in official build till next month release.
If Seibu Cup Soccer can be emulated, consider that fortunate because I am guessing Zero Team is a ways off.
src/mame/drivers/legionna.cpp Seibu Cup Soccer
src/mame/drivers/raiden2.cpp Zero Team

Zero Team should be better emulated than it is. It runs on similar hardware to Raiden 2, but makes more thorough use of COP functions. However, New Zero Team and Zero Team 2000 use a less functional COP replacement and reimplement many of the COP functions in straightforward V30 code, so that has already been of some comparative utility. Specifically, I used it to improve the sprite-sorting DMA, though that also made the starting bikes disappear from Zero Team until I added sprite buffering as well. Zero Team still has some sprite priority bugs, though.

Hitbox and enemy movements i think are the main sticking points for Zero Team.?? but as you mentioned
at least we have Zero Team 2000 and New Zero Team in a good working state, as for Seibu Cup Soccer
there is a working bootleg Goal 92 to fall back on.

The hardware protection Seibu was using for some of their 1990s era games is all the more impressive that it has lasted longer to this day in still making a few of the Seibu games not yet fully playable. Have to give Seibu credit that their 1990s era hardware protection worked very well in preventing bootlegs from appearing back then.
If looking back about 8 to 9 years earlier, it was impressive that a whole bunch of Seibu pcb owners were working with Kale and Kale's test patches that were written to see how Seibu pcbs were running. A lot of work back then to get a lot of the hardware documented. Crossing fingers that there won't be a need to do that stuff again with remaining 1990s era Seibu games.

iirc years earlier someone had jokingly stated Seibu protected some of their earlier 1990s era games so well that they accidentally locked themselves out of the house. :-) It was likely either RB or OG that said that quote. Maybe why fewer functions were used when the newer games were released.

But if we talk too much about Seibu hardware progress, will Kale stop working on it?

It's only if the Seibu games fanbase started latching on to Kale like the monkeys do on first stage of Sega's Congo Bongo. If it comes to that and Kale has to jump up and down to shake off the Seibu fanbase kidz, then I can see it ending.

Jesus, dude, let me get some nails for that cross you keep nailing yourself up onto. You know what makes people stop working on things? Your fuckhead attitude. Shut the fuck up.

As a forum lurker and MAME user only (i.e. not a developer) allow me to say your bad tasted, tiring "jokes" also stink... big time!
I've never seen before someone so ungratefully receiving Konami M2 emulation after being a pester here about the topic for years. And you still keep going on.

I was finishing zero team after raiden2 when Haze changed all the fucking seibu code under my feet and blew all my tracing code. Since then I haven't touched that code and probably won't. But yes, comparing with zt2k works.
