Super Real Darwin (World) srdarwin - sprite priority problem - dinosaur on left and bottom

I tested the MAME version and here the "dinosaur/big lizard" sprite priority is accurate... I also attached a savestate (FBA release) to help the check...

Megadrive emulation has improved a bit more, thanks to Pityesz for letting me know about this bug.
highlight/shadow needed to be implemented for the 2-cel vscroll tile mode, after that, the Trouble Shooter / Battle Mania intro looks much better...  See the before/after pics:

not for long.
I wonder what regressions you found, exactly. But I guess you gave the details to dink.

quizhuhu is a bit beyond repair, unfortunately.  That one should probably have been left out.  The others are very solid though.

The taito bootup logo is missing too.  quizhuhu kludge was more like a crapshoot, at least some text was shown (just like in mame .97)

Don't expect any consistency to be applied. Games being playable, but emulated completely incorrectly are preferable for MAME, despite the projects supposed intended mission.

This is why FB Alpha is ahead of MAME for CPS-1 bootlegs, even though most of my work has been ported across now.

I always avoided Nitro Ball because I thought it was a ball/sports game.   As it turns out, I was wrong... its really an awesome game sorta like Heavy Barrel!

As Gab75 pointed out the other day, Nitro Ball had some sprite priority issues, those were fixed.   Also translucent/alpha support was enabled.

The last picture shows how things were before the priority fix.

Excellent work! :)

PS: as dink wrote me, to enable the alpha compositing (translucent) effects it's necessary to set a full 32-bit "color depth" mode...

Recent news from my side..
Dataeast deco16 games all had their prot sims removed, and replaced with propler emulation.  This made it possible to port and play Double Wings without any issues.

Fixed raster effects in Ed Randy / The Cliffhanger, now the road and flying w/clouds scenes look alright :)

Tuned the sprite:tile priority in Nitroball, this leaves all but 2 sprite priority issues left, but that's not bad considering there were about 20 before I started :)  I think the only way to fix the remaining 2 issues is with a silly kludge.

Hello everyone, here's some fba-emu news for today:

Fixed lots of timing issues with Data East 16bit games when sound runs at 44100hz, among the improved games: Caveman Ninja, Robocop2, Desert Assault/Thunder Zone.

Fixed a banking issue in Boogie Wings, some pcm sounds (f.ex: rhythm section in music) were missing.   Along with all the other recent fixes/upgrades, deco16 games are very solid now. 

Lastly, Pitfall II on Sega System 1 was leaving a mess of sprites on the screen during transitions.

That's all for now...

best regards,
