I was experimenting recently with running WB on Mister AGA with some higher resolution, but failed. The problem is that HD720 is running at 47Hz which is not accepted by my Samsung TV. Is there any way to tweak HighGFX40_6's HD720 to make it run at 60Hz? I presume it would be to high pixel clock for real AGA, but how about MiSTer AGA?

Keep in mind these modes are also Interlaced. You must send the VGA through the scaler...

MiSTer.INI:

Code: Select all

[MINIMIG]
vga_scaler=1   
video_mode=0

No way it will run HD720 on 60hz. Pixel clock is fixed to 28MHz. Even if your monitor could handle 47Hz, it wouldn't probably handle 720i resolution anyway. You need true multisync monitor from Commodore to display such resolution over VGA.
For MiSTer these resolutions are supposed to be output over HDMI through scaler.

If your Samsung is picky about displaying the feed from MiSTer, then you should experiment with MiSTer.ini

I have same issues :

https://www.youtube.com/watch?v=wBIbvwqs2d0

And Rygar AGA and Pinball Illusions 1.5 AGA don't works neither (these two now works both fine on Mist)

Maybe something needs to be fixed on Minimig for Mister

Just to clarify, the graphical corruption you mentioned is appearing as single-color horizontal lines?

Also, any idea on which release or when these issues might have started to surface? I'm just trying to narrow down the window for review.

Not OP but im getting this problem as well. Havent been able to use any of the cores since the clock speed was increased but it was fine before that and since its been decreased again it has this issue

Here's something you can try, includes the fix to tg68k from today.

Thank you very much, this evening will test it!

Mostly yes, in some games is more frequent, like the First monkey Island, in others is less presente. In Rygar remake it's all corrupted and the game freezer, don't know if it's related. Will try the test versione posted. Another strange behavior is that's impossible to create a configuration with kickstart 1.3 and no slow ram, It crash the core.

I've made some test with the testing version:

- PINBALL ILLUSIONS now works! Great! Tried ADF 1.5 and WHDLOAD versions, both work.

- Graphical glitches still present, it's more easy to see them in the whdload version of Monkey Island (i'm using the italian version), i've seen them also in pinball illusions whdload version.

- RYGAR AGA stiill not working good (final release) horrible graphical corruption or freeze.

- Trying to make a config with kick 1.3 and any amount of chip ram without slow ram not work, the kickstart not boot.

- Secret Of Monkey Island is a good test for some bugs: Trying a config like A600 with ADF version result in a crash during the intro with the music, tryng an A1200 config with ADF version corrupt the sound.

- These are others test that i do and fail in every release: ADF versions of Jim Power and Pang! crash when is expected to go in game instead. The AGA fixed versions (so the whdload too) ADF instead works correctly with a base A1200 config

Thanks for your time.

Same behaviour (or worse) on Monkey Island 1, i think that problem may be too much low clock used con SDRAM..

These glitches are due to overall core metastability problem. It's not related to bugs. You just happen to have de10 working less stable in that build. Other seed value may get better result. And of course cooling for de10 reduces such tolerances.
For me Rygar, Pinball Illusions, Monkey Island - all work fine without glitches.

Not sure to have understood (too technical for me, sorry), but more or less three version ago i've never had glitches or graphical artifacts, hope next versions i'll be more lucky :-D the other issues i've talked about, not related to graphical glitches, are bugs of the core? Thank you again.

Minimig doesn't emulate A500 in terms of speed. So if there are some old games expecting slow A500, then they may work incorrectly. One of the main reason of WHDLoad is to tune environment for picky games to make them work on later accelerated Amigas. So if there is a WHDLoad version - you have to prefer it for better results.

I have the Mister with the 32mb SDRAM module and I put back the Minimig Aga core dated 23 September 2019 and it works perfectly with Monkey Island 1 (not tried Rygar Aga or Pinball Illusions Aga yet), while a friend told me that on his Mister with 128mb sdram it Monkey Island 1 works perfectly and he is thinking that probably the lastest Minimig cores may has been tested with the most recent 128mb sdram module only, which apart from the amount of ram on board, is not technically identical to the 32 mb one.

Probably at this point the solutions could be either buy and install 128mb sdram module or continue to use the old 23 september core

I have 128MB RAM and both, the floppy version on an Amiga 500 config and the WHDLoad version on an Amiga 1200 look fine. I use the latest public version of all cores via updater script.

latest release use 57MHz for SDRAM, so any SDRAM even badly soldered (but working) will work. It's just generic timings problem in the core - mostly due to TG68K cpu.

I've noticed a little weirdness the other day. When I turn off the ICache in SysInfo, the reported frequency drops in half.

Sysinfo never detects correct clock in Minimig. By disabling the cache the performance drops a lot. So it may affect the clock detection.
