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

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.

best regards,

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! ;)
