Moo Mesa should be alright now - I fixed the sometimes missing sand layer infront of the monolith in the intro & added a filter for opposing joystick directions.

Howz it looking for these three badboys..?? ....SPRITE GAPS THE BANE OF MY PAIN...!!: :mad:

Sometimes the "separation lines" as sprites expand/reduce (scaling effect*) are normal. Let me clarify: often it's intrinsic in the "approximation" of the emulation (maybe a more accurate emulation could be solve the issue, but it's a very complex task). I'm pretty sure that it's the case of Konami's The Simpsons (the "bug" happens both FBN and MAME) and, probably, it's also the case of "TMNT Turtle in Time" and "Bucky O'Hare".

* especially when the scaling is asymmetric, different zoom-factor between the axis X and the axis Y.

Probably in future this and other "limitations" (emulation side) will be overcome, but now it's impossibile to know when it happens! :)

If these 3 remaining titles get fixed - konami emulation will be more or less complete on fba...!! It'll be another feather in the cap and i'll be celebrating like a madman. :biggrin: :biggrin:

I'm sorry to dampen the enthusiasm, but for now it's basically impossible to solve the issue (zooming/line-bug):
all the greatest minds in emulation couldn't fix the sprite zooming/line-bug over the past 20 (or more) years, and it probably won't be fixed any time soon. For now the only way to solve the "issue" it's to buy the real pcb's! ;)

many many days went into perfecting the emulation of this one.  Big thanks to Gab75 for super-playtesting and bug finding and iq_132 for emulating it and doing his usual nice optimizations and stuff. 
The steering alone took almost a week to get right, with about 10 revisions :)

Is it possible you could record a movie file (input recording) and do this move, because I can't play these types of games.
Recording inputs is easy:
click "Game -> Replay -> Record Input" after you get the game going
perform the move(s), after it glitches do "Game -> Replay -> Stop Replay/Record"

play the recording back using "Game -> Replay -> Replay Input" to make sure it replays back with the glitch, then attach the file from recordings\romsetname.fr

thanks and best regards,

for barbudreadmon: we'll probably have to emulate the dmastatus register for this.  I've been thinking about it every so often:  pretty sure I've come up with a way we can do that now without causing much of a performance hit. (or probably none at all)
