the_maq will you post a savestate file at this point in the game?
"Game -> Save States -> Save State", then use the "Attach:" function while writing a message.

the_maq, thanks for the infos & state files, I'm working hard to get xmen6p as close to pcb as possible as far as video goes, I've got nearly all the video bugs except stage 5 fixed so far.
I'll also take a look at the 4p version to see what's happening there.

best regards,

Dear friends & fans of FBNeo,
We have a (theoretically) pcb-perfect xmen 6p now.  woohoo \o/

All of the video bugs - at least, the ones I know of - are fixed now.  It will be up to you guys to find any remaining bugs so we can have an even more perfect xmen 6p. :)

The stage 5 bug was tricky!  I'll try to get a fix for the 4p xmen continue issue in there before I put the new code on git, .. expect it by Friday night if things go well!  Thanks for finding those bugs, the_maq.

best regards,
- dink

image notes:
everything except st5: fixed linescrolling (raster-like effect) on second screen
st5: fixed tilemap selector

xmen 6p fix is in, as well as a fix for the 4p 'continue' diagnostic/romtest screen.  The game actually partially crashes when all start buttons are pressed at the exact same time during a single frame @ the continue screen.  One could actually cause different crashes by holding different combinations of the start buttons.  Anyhow, a little work-around was added so causing that problem is no longer possible.

I'm not sure about the black box "floating" in the water, it's in every playthrough video I can find of the game, although I'm not 100% sure any of the videos are real pcb or not.  Would someone care to try to find a pcb-recording at that point so we will know for sure? :)

p.s. the black bars as the elevator scrolls down in level 5 on the far sides of the screen is normal and not an emulation bug - at least, I'm pretty confident is isn't.

I found a recording of a real cabinet (6p version) and there isn't any "black box" floating in the water (at least I can't see it)...
look at min 14:45: https://www.youtube.com/watch?v=RnbZgcRtVCA

NB: the "problem" is that the "black box" appears only for a while (excactly for 8 frames), so it's difficult to notice it in a video of poor quality.
Moreover I have a question... the savestate (xmenu 2.fs) starts from the last three seconds of "ocean cut-scene", so I ask, is the "X-Jet sprite" visible during the entire cut-scene?

Gab75, the black box is in the 4p version, the 6p version it might be fixed (I'm not sure if it is, but the continue crash-bug doesn't exist in the 6p version - I'd assume they worked a little harder on the 6p version)

It turns out the black box _is_ in the actual PCB.  Here's a pcb recording: https://youtu.be/qt0j7mPBUB0?t=617
it's Konami's fault this time :)

Wild west cowboys intro bug - the ground goes missing then bounces back later on, kinda on and off like a radio (capture 1 and 2) also a lever error pops up during gameplay in capture 3..??

the_maq,
"Lever Error" will display when you press 2 opposing buttons at the same time (left+right or up+down).  Fun fact: a lot of games will actually crash when 2 opposing buttons are pressed, so we put a filter on them to ignore opposing presses.

The missing "sand" layer happens somewhat randomly during the attract sequence - sometimes the game disables this layer, the reason for this is not yet understood.  I'll try to revisit it to see if I can come up with anything.

best regards
