@zakk4223, thanks so much, that worked. Any chance you (or somebody else) has a list of (arcade) cores that require 50hz video mode? No, I don't know of any. Maybe if you look at the list above and find the other cores that have similar horizontal and vertical refresh rates that might be a good start. It's some interaction between the core video t...

Yes, it will change for any game that uses the scramble core

Use a 50hz video mode with the scramble core (this doesn't cause it to run at a different refresh rate, it just allows it to calculate a working pixel clock)

put this in your ini, at the bottom.

[A.SCRMBL]
video_mode=9

Are you using vsync_adjust=2?

I suspect if none of the existing converters are capable of reading your images that if anyone decided to write support for Mister, they would also not work there.

You have to go into the in-game configuration menu and change it in the sound config.

:?: the mra refers to zerowing.rbf, not zerowing_ok.rbf. In any case I followed your suggestion and guess what ... it works :shock: It does not make sense but your suggestion is correct. What is going on with MISTer? I was under the impression that it somehow(?) scans all files for the internal core name, rather than the file name. And quite often...

After your first post I built the core, renamed my previous rbf to zerowing_ok.rbf and installed the newly built rbf but got the same results. In my experience, renaming does not help; you have to actually move it out of that folder. ... :?: the mra refers to zerowing.rbf, not zerowing_ok.rbf.

AO486 is already tight in both FPGA resources AND timing. It may just be that getting it in there was going to push things over the edge. That core is already in a state where it doesn't necessarily successfully compile every time. Almost any feature you think 'why doesn't ao486 do this?' the answer is FPGA resources/timing failures.

The mister code TRIES to detect if the image is writable before it opens it RW, but if you look at your mounted directory all the files are probably mode 0755, so that code ends up opening RW because the file is RW (but not really) If you look at the mount, it is likely has the options file_mode=0755 and dir_mode=0755 set. In theory those are fallb...

Double check the filename in the cue exactly matches the bin filename, especially case. The CIFS NAS may be case sensitive and the local file system is not. edit: there were also people that were having issues with permissions on the CIFS server because the PSX currently reuses the 'vhd mount' code path in MiSTer and that opens the bin file RW whic...

The original machine had a dip switch to change between 15khz or 24khz. Although I guess maybe 24khz is "weird" so who knows. I believe since this is a ported puu core, it is not yet outputting original video signals. Some of Puu's other cores have built in scalers that force 31khz (X68000 was the same way). It's on the todo list, per the...

There is no CHD support. Assuming no one adds it when they also deal with cue file parsing, I will look into doing so. But only after development has settled down a bit.

It looks like the PR removed one line from the MRA that is part of the high score saving system, so it's probably saving and restoring to bunk addresses.
I don't know if it was removed by accident, but it needs to be there. Restoring it should fix things

There are issues with MIDI, I believe Kitrinx said there are some unimplemented interrupts.

Some games work with it, others will just hang

It should work just like the old TDL system did, where the exodos converter created the bat file which contained commands to mount the cd images out of ao486/cd directory. I'm not sure if flynnsbit has converted commercial games over yet, but I can confirm my own hacking of exodos converter to create autorun.bat basically works unmodified with myme...

It kinda did. https://gamesx.com/wiki/doku.php?id=controls:x686button Basically a handful of games had support for more buttons but not the system in general. Those worked by strobing the select pin and reading the data "twice". And then there's this thing: https://gamesx.com/wiki/doku.php?id=x68000:cyber_stick I believe analog mode requi...

Thanks, I think I got the mras and I will test later. So at this time the new core and mras do not bring anything really new but just open the door for homebrew/hack. The strange thing is that when I did the update the mame/hbmame getters did not get anything new, I guess I will know more when I test it later in the day. It shouldn't need to downl...

?????

ao486 already supports shared folders just like Minimig.

The columns are one character wide. Just resize them

Works fine here. Delete /media/fat/config/SNES_scaler.cfg Set this in MiSTer.ini [SNES] vfilter_default=Composite Blend/Comp_Blend_H_100.txt Next time you load SNES core it should be using that filter, and that filter will be listed as the active filter in the OSD. Make sure the SNES section is after the main [MiSTer] section, especially if your Mi...

That parameter CAN be used core specific, but it requires you have no saved scaler settings for that core. In other words, if you have a /media/fat/config/SNES_scaler.cfg file, it will not load vfilter_default, but use the 'saved' one. Note that 'no filter' is still a 'saved' filter. edit: it looks like there is some condition where the file can ex...

Why did you link manuals for the FP731 when the poster probably means the BL702A?

Actually I lied. It's most in ide.cpp these days.

It's not actually complicated, x86.cpp uses defaults. 16 heads, 256 sectors per track, (file_size / (heads * spt * 512)) cylinders

All that stuff is done in Main_Mister. Look in support/x86/x86.cpp

Keep in mind the update script (the "old" one, not the new downloader) parses the wiki page for valid core links. So if you're going to edit that be careful how you do it.

It would be a good idea if this core was pushed into the official repo. I do not use the new downloader so the rbf and mras do not disappear from my MISTer but as the mra names differ from the official ones I have extra mras which are useless. Someone with a Twitter account should contact him in this regard. All his other work has ended up in offi...

I assume that's because the background music is CD Audio and the ao486 core doesn't currently handle that.

Friend, the public beta version is not the same as the Patreon version, meaning my version doesn't have the "Turbo" option The turbo enabled double dragon core is NOT patreon exclusive. It is 'beta' which you can enable in update_all. I do not have the proper patreon unlock rom at the moment, and the DD core works fine for me and has a t...

No one needs to share it with you, you get it with beta option enabled. The Double Dragon core isn't patreon only, it was a public beta release.
