Black screen on some arcade cores. Any idea how to fix?

[pbsk8]

I am running cps 1 and cps 1.5 normally but some other arcade games such 1941 and 1942 all I get is a screen like this:

for 1941 I see there is an option in the menu *load .rom:

I used update all to get all the roms. Something missing here?


Contra is the same, I get black screen and I see this:

for gun smoke, I get a black screen and I get audio in the background and then the sounds starts an annoying loop. And I cant do anything but reset the mister


Can somebody help me fix these issues? I just got my mister fpga kit.

Try changing the screen orientation. It is as often the vertical CPS games to show up horizontal or upside down. There are two methods using the core itself or the dip switches. Hope this helps.

I believe that's an issue with vsync (cores outputting an unsupported refresh rate signal to your monitor in a given resolution).

Try setting vsync_adjust=0 in 'Mister.ini' and then go from there with each core.

and what about contra and 1941? Do I need to create a folder for them? I thought that update all script would organize everything.

I found a mister_example.ini inside the microsd, and this vsync_adjust is equals to 0 already. I dont want to mess with it because it could change for everything else.

I thought every core had it's own ini file so this change could be made. The thing is, why is there an option to load the rom since I already ran the game?

Some Arcade cores have given me issues like that, one work around I found was dropping problematic Arcade cores down to 720p. I didn't want to give up latency by using V_Sync=0, so I dropped resolution instead and kept V_Sync=2 enabled.


Also, you might just want to delete your Arcade folder and start over.

can you run 1941 and contra? do you have a folder specific for them? I ran update all script again was successfull.

And still didn't create those folders and also didnt download the rom.

How can I set to 720p individually for a certain core? And settings also vsync_adjust to 2 individually for a core?

You have to be doing something wrong if its not pulling in the roms for Contra. Do you have everything enabled for Update All?

Contra and 1941 works fine for me, no issues. I don't do anything special, Update_All just works for me.

For custom resolutions You have to type it in manually in the ini settings.

For example I have Frogger set to 720p, so I type in

[Frogger]
video_mode_ntsc=0

I'm gonna test something. I'm going to remove all the necessary Contra files and run Update_All and see if it pulls everything properly, I'll report back.

[SegaSnatcher]

Ok, so I deleted all necessary Contra files, RBF, MRA and Rom. Then I ran Update_All and it worked just fine, so there is some user error on your end.

Also, don't worry about the load rom feature in Contra core, the game should auto boot.

[FoxbatStargazer]

core-specific settings go in the main .ini file. At the end of the file you need to start a block with the core name in brackets, where core name is whatever is displayed in the menu while using a core. Then just fill it up with as many options as you want before starting the next block. Example for AtariST and Amiga:

[AtariST]
vsync_adjust=1
vga_scaler=1

[Minimig]
vsync_adjust=2

that's odd. I ran update all script again and after checking everything it says it went successfull. See this image:

Could you show me a print screen of your folder section where is 1941 and contrae folders? I just want to make sure where to create these folders and maybe

For example, at first it didn't create a ao486 folder, it had an error during the BIOS GETTER. After I created this a0486 folder the script downloaded normally. I just wanna know where is this 1941 and contrae folders

and where is this main ini file? Is it the same mister_example.ini?

[FoxbatStargazer]

mister.ini at root, mister_example probably isn't doing anything with that title because its just an example.

The main MRAs will just be in the root of the Arcade folder.

I have used another 32gb kingston to install mr fusion and then update all script. Now 1942 works and gun smoke as well.

But 1941 and contra both have those video issues that I posted above and also saying missing directory

that's the structure of my arcade folder

could you give any idea where to create this folder? because update all shows that everything went successfully

[SegaSnatcher]

There is no folder to create. Make sure you have the mame roms in games folder.

Also, the fact you don't have a MiSTer ini is weird.

[FoxbatStargazer]

it might be generated by running the ini_settings script? hit f12 twice in the menu core and choose scripts, then ini_settings. Change your settings (or not) and be sure to save when done.

[pbsk8]

Now, out of the blue, 1941 and gunsmoke both are working without any issues, I didnt do anything.

And I realize Mercs has the same problem as contra, just black screen.

I will tru to run this ini settings and see if the ini file is generated.

I have found this thread here, other person having same problem with the mister ini not generated

Check if you don't have two folder mame !
/_Arcade/mame
/Games/mame

if you have two and the content is different..... It's better to have only one folder

there is only one folder mame and it is inside games folder.

On _Arcade there are only mra files and _alternatives, _organized and cores folder

the issue still is about the black screen for mercs and contra

And you have the mame files ? contrae.zip contra.zip mercs.zip
also check, if you don't have multiple versions of the same core

Try also in your mister.ini file:

[Contra]
vsync_adjust=1

I ran ini settings from scripts. And then the mister.ini was generated but then I have this on screen.

I am afraid to change here vsync and it changes for everything else and not only for contra and mercs

IMG-20210127-180332.jpg (3.14 MiB) Viewed 4186 times

So I opened it here on PC this mister.ini. My mister.ini is similar to mister_example.ini and in the end of the ini file I added

[Contra]
vsync_adjust=1


About the roms, I have only contra.zip inside mame folder, there isn't contrae.zip . There is also mercs.zip


Now mercs and contra are working!

But If I added only vsync adjust for contra, why did it change for mercs as well?? I am afraid now it will mess with every game on my sd this way

What is the difference between vsync adjust 1 and 2?

[tontonkaloun]

; Set to 1 for automatic HDMI VSync rate adjust to match original VSync.
; Set to 2 for low latency mode (single buffer).
; This option makes video butter smooth like on original emulated system.
; Adjusting is done by changing pixel clock. Not every display supports variable pixel clock.
; For proper adjusting and to reduce possible out of range pixel clock, use 60Hz HDMI video
; modes as a base even for 50Hz systems.



Everything works because you are in vsync_adjust= 0 for all your cores in your mister.ini file

I see, now that the ini file was created , it applies to everything

I know the description for vsync adjust you just posted,

but I mean what is the difference between 1 and 2 in layman terms. I have a fullhd 27'' 60hz monitor, will this option 2 be any different or decrease input lag?

[aberu]

2 will technically on some level reduce input lag by likely unnoticeable amounts if your monitor can take advantage of that, but it can increase the chance you will get display problems. The main advantage is the smooth scrolling, if your display doesn't have issues with it.

[Contra]
vsync_adjust=1

...

But If I added only vsync adjust for contra, why did it change for mercs as well?? I am afraid now it will mess with every game on my sd this way

What is the difference between vsync adjust 1 and 2?

I think you need to change this to:

Code: Select all

[jtcontra]
vsync_adjust=1

Since that is the core name, no?

For arcade games, not the core but the setname:

Ahhh, didn't realize that, my bad! I was confused at first lol

currently my mister.ini is like this vsync_adjust=0, this zero means what?

I even removed the [contra] in the end of the file and it and mercs keep working normally.

I think I will try vsync_adjust=2 and see if my monitor (27'' fullhd 60Hz 4ms) handles it well since it decreases the input lag, it would be better in this case.
