GroovyArcade live-CD 2020
Calamity:
Try reducing horizontal front porch and vertical back porch. I'll use the -dpi trick, thanks. Btw, is dkong stii wide screen?
NightSprinter:
I intentionally set it to 3:4 aspect for widescreen in the setup from the LiveCD. So I actually have it so all vertical games are put into that ratio (with my spine as bad as it is, I'm not about to attempt to rotate a CRT that's 1.5x my body weight every time). I've also added additional modelines, as games like Kobo Deluxe have multiple resolutions (so if someone else playing it on this game wanted another resolution, they could switch to it). I do think in the past on the previous version of GA, just using the steps you mentioned did not work for playing Rom Check Fail in fullscreen mode. Anyways, here's the verbose output from dkong. As mentioned, even when I have XRandR switch the desktop to the default 648x480 interlaced resolution, the display seems to be forced to the left considerably. It's definitely not a default issue with the emulators, from what I can tell.
[Edit]
Okay, so it seems this happens on ALL modelines that run at 15KHz and not just instances like Donkey Kong or the default resolution set up for X. Maybe a bug or something with the kms driver?
mamenewb100:
Few bugs and updates for you. I found the same bug I had before with GA not loading properly in grub.conf using 640x480. I found using 800x600 as my bootup works for some reason. So that's not an issue but good to note. Could be a conflict with my monitor.
Internet through network cable works but wireless does not. I put in my correct wireless ID and password.
The default Makvision 2929D monitor setting does not work on my display. I can use the default setting for 31K and it works fine.
Scanlines do not work in VESA mode but I'm using an ATI card and you were saying it might only work in NVIDIA.
Main problem I noticed is that GA is ignoring my crt_specs0 line in mame.ini. I was trying to change the horizontal frequency to 32K since my monitor has issues with games like MK on default 31.4K. It keeps using 31.4K even when I change it in Mame.ini.
NightSprinter:
Seems to be similar to some of my issues. Do as I did, and post some logs in .txt format. Do the same with your mame.ini/ume.ini files in .txt for the authors. If you need to, do this:
--- Code: --- groovymame mk -monitor arcade_31 -verbose -log > mk.txt
--- End code ---
For my issue, I have lowered the horizontal front and back porch to try and move it. It seems to result in the same thing mamenewb100 has noticed. Also, ves, Ansa89, Calamity, whether tonight in the next hour or tomorrow after work would you guys like me to pop in the old X300 in place of the 6700 I'm using to compare how things are between XP and Linux on what MAME is doing?
mamenewb100:
I was able to fix the problem by changing the monitor setting to "custom". Now it reads my mame.ini and even better.. the 120Hz mode actually works much to my shock! My monitor can't get over 80Hz in 31K mode but as others have pointed out, 320x240@120Hz essentially the same as 640x480@60Hz.
The original settings warped my screen because the issue my monitor has with low horizontal frequency settings. I had to bump up the horizontal frequency a little bit and get almost full screen scanline awesomeness now. I've noticed that the games don't have perfect doubling of the refresh and are off by about a frame causing slight jitter when their is scrolling. I'm thinking that may be a side effect of doubling the refresh.
