Games with ISSUES: report here!
Heian_Shodan:
Does anyone have any idea if there's a workaround to the Apocalypse/Onslaught Sprite problem on Xmen vs SF, Marvel vs SF, and Marvel vs Capcom? It started on Mame 145 and never got fixed. I dont know what they did to the Cps2 code that caused the issue. It was perfect before that version.
Here's a gif:

Hello,
I read the procedure to report a game issue but sadly I’m not in front of my cab, just texting on mobile.
Hope to not be ignored though...
The game I’m experimenting issue is moon cresta.
The problem is that strangely intended to be as a 768x224 @60.606061 while as far as I know the resolution should be 384x288 @60.606061
I got a monitor wit horizontal orientation and I rotate the vertical games without any problem keeping their right resolution and timing (I got a polo star 28” modeline 1) but with 768 lines of course my monitor goes to interlace giving the timing problem as the game runs at 25hz probably due to the windows interlacing bug.
Is there any way to let GM to handle moon cresta as the right resolution should be so 384x288?
As far as I concern. The problem should be present in Galaxian too as they share the same resolutions and refresh.
Thanks
Torkyo:
hello,
to fix the interlace problem I disabled interlace in mame.ini
anyway the problem remain as the switcher works handling a wrong resolution of 768 lines (rotated) instead of 384.
I'm wondering if is there a way to force the correct 384x288 resolution.
attachment follow with required details.
- mooncrst
- ATI RADEON HD 4350
- Hantarex polo star 28" tri-sync
- CRT Emudriver 2.0 (12.6) Windows 7 64bit
thanks

Hi Torkyo,
384x288 is not the correct resolution at all.
That game has indeed a resolution of 768x224. But because it's a vertical game, and you want to play it on a horizontal monitor, 768 becomes the height in lines, and that's not achievable for a 15 kHz monitor.
Older GM versions had a patch for those specific games that divided the 768 resolution value by 3, to 256, so they could be played on a horizontal monitor, using a resolution of e.g. 400x256 pixels. This hack was removed because it degraded the backgrounds' resolution for users that intended to play them on their original, legit orientation.
So since you're using super resolutions, the workaround could be forcing them to run on 2560x256 (create a fine named mooncrst.ini and put "resolution 2560x256" in it). However GM is not designed to downscale cleanly and you'll probably notice ugly artifacts when doing that.
Torkyo:
Thank you very much for your kind reply, Calamity.
my information about mooncresta resolution was wrong then!
luckily I got a monitor that accepts 15 25 and 31 kHz and the switcher changes resolution to 2560 x 496P 60.606Hz 31.515 kHz
the problem is that I notice a little glitch in the vertical scrolling, I think it is because of downscaling from 768 to 496.
Probably with such hi resolution (768 lines) it is the best possible way to display it in vertical over an horizontal monitor. I hoped to have the perfection like in all other vertical games I tested so far but probably such 768 resolution is too far.
If you have any other idea to improve the mooncresta picture I'll be glad to listen about that!
thanks again.
