Turbo Outrun (toutrun)

Minor gfx glitch when screen fades dark on high score table / title screen.
Vehicle shadow turns yellow.
The glitch can also be seen inside the top half of the speedometer

I have attached comparrison shots from FBNeo and MAME

(Out of interest, I also noticed that when flicking between the 2 images, the foreground elements (incl title) seem to offset by about 1-or-2 pixels.
The background layers stay consistent.)

retroFuture,
Thanks for your bug report, the shadows have been fixed.  I'm not too sure about the positioning, so I'll just leave that as-is for now

Ultimate mortal kombat 3

I have no idea if they have solved it in the most current versions of mame (I stayed in v0.220), but I have always noticed a sound error in umk3, to be more precise, in the scorpion power when it launches the harpoon.

It is supposed to say the phrase "get over her" or "come here" when he throws the power and catches the rival, however in the mame versions the phrase is not completed, remaining only in a simple "get ov.... or "come...".

And I'm sure that in the original board (I had the revision 1.2) it completed the phrase since I had it around 2006 and I sold it around 2009, and I got a lot of juice out of it... besides my fighter was scorpion.

Reading in internet, I knew that the original board (revision 1.0) had this problem but it was solved in the revisions 1.1 and 1.2, however in these last ones the bug is still in mame... at least in the 0.220. I haven't tested the last one since it goes to pedals in XP.

Ah, of course, the bug is also in FBN.

Greetings

Pelucon8, the problem here is that the dcs rom & program data for the adsp cpu core (which controls dcs) is the same for all umk3 versions, which most likely(probably) means that they dumped it from a first version board.  To get the fix, it would most likely need a dump of the dcs roms from a version 1.2 board.  If someone has more info about this, or cares to correct me, do chime in..

FWIW here are some video that alledgedly prove that the bug is present even on real hardware on version 1.2:

Well, if the pcb's in the videos show the same sound "error", then nothing to do. It must be like that.

Who knows, maybe I was lucky enough to have a pcb with some modification that fixed the scorpion sound. 

Thank you very much.

... Inspired by VS. From Below @ https://mhughson.itch.io/from-below

VS. Unisystem is added to the NES emulation

It supports VS. Unisystem roms in .nes format w/ NES v2.0 header, the v2.0 header can specify all of the important stuff the VS. games need to run properly.  Plus they are compatible with other NES emulators.
I've attached all the NES 2.0 headers, as I painstakingly configured each game, and -except for VS. From Below - VS. roms with perfect headers don't exist in the wild yet.

@ dink

VS. Unisystem added to NES emulation but in Arcade Games datafiles, right?

[dink]

JacKc, yes, it's an arcade machine   p.s. please see pm about a detail

Got major sound distortion playing Dead Angle with Low Pass on.

Hi JoelH,
Thanks for letting me know, though - this one was recently fixed, please update and give it a try

Great! Now also the coin-op version of NES/Famicom is emulated on FBN... 

[WILOWAR]

Playchoice 10 is another or similar to Vs
Arcade  Version  of Nes???

[dink]

WILOWAR,
Playchoice 10 is useless to emulate for FBNeo.  It just is a regular nes - which we already have, with a timer that counts down while you play the game which is controlled by the amount of coins you put in.  Please read about it.

Must not have flown down to libretro yet then. I'll keep trying.

EDIT: Ok I just found out something. When you get hit, the game's sound suddenly gets filled up by what could be best described as white noise. That might be the source of the problem.
