I used these settings in the mame.ini
arcade15khz preset
crt_range0 15734-15734, 59.90-60.00, 4.700, 4.700, 6.216, 0.191, 0.191, 0.953, 0, 0, 224, 224, 448, 448
crt_range1 15734-15734, 59.90-60.00, 4.047, 4.700, 5.449, 0.191, 0.191, 0.953, 0, 0, 232, 232, 464, 464
crt_range2 15625-16200, 59.90-60.00, 3.207, 4.700, 4.650, 0.191, 0.191, 0.953, 0, 0, 240, 240, 480, 480
Am I blocking out the ability to use 256p with these settings?
I thought the point of using the arcade preset would have been to allow me access to that range.
When I leave default settings 256p works, but as we both know we end up with a very ripply image. However when changing the range to 59.90~60 I loose 256p. I can understand that games in a low range such as MK and Irem games would not be able to switch, but for a game like Denjin Makai which runs at 61hz and 256p I thought it would work, but instead it reverts to 480i even if I leave 61hz max range purposely to see if I can get it in progressive scan. I'm confused as to why this happens.
As a separate question, I would like to separate 240p and 480p if possible. Is such a thing possible even?
I get a really nice noise free signal for progressive video when limiting the other range to 15734-15734 (59.90hz stops the water ripple effect but the other range seems to determine noise levels), however for some inexplicable reason in interlaced modes it's the reverse, I get more noise with that setting and I get less with a more flexible range (such as 15625-16200).
Here's what i tried to do to seperate the settings for 240p and 480i. I tried adding a range3 like this:
crt_range2 15734-15734, 59.90-60.00, 3.207, 4.700, 4.650, 0.191, 0.191, 0.953, 0, 0, 240, 240, 240, 240
crt_range3 15625-16200, 59.90-60.00, 3.207, 4.700, 4.650, 0.191, 0.191, 0.953, 0, 0, 480, 480, 480, 480
However when doing this 480i ends up in 464i which is worse, so for now I reverted to the settings show first in this post.
