MiSTer FPGA Forum

Yeah, I'm in the camp that a 5× with vertical crop mode would be more trouble than it's worth, at least at this stage. The MiSTer can always be connected to an OSSC in the meantime. I have had my mister connected to my ossc, and had much worse issues with having to fiddle with the ossc sampling options for mister than with original hardware (conso...

Very cool! Just curious, does it perform hue rotation (esp regarding the "interesting palette changes")?

I don't think we have any sort of custom cropping as a core mister feature at this time. Some cores have specific cropping for known common sizes, though, such as Neo Geo. If I understand the OSSC documentation correctly, I think your display has to "play along" with the OSSC to be able to resize the screen. Otherwise, I think you are at ...

Growing up, one of my neighbors had a SNES hooked up to a monitor (via composite) that may have been a Commodore 1901 or similar unit (going by internet pictures / my memory). It would reliably roll picture on (I think) Butter Bridge 2, in SMW, one of the brightest levels in the game. May have been similar behavior?

I don't think the updater updates mister.ini after the initial install. I usually grab the latest mister.ini and use a diffing tool to merge in any updates.

Caveat: My mister is a bit out of date and does not have the forced vga scaler change on most/all cores. I hooked up VGA on an LCD to see what video mode was being reported with vanilla mister.ini and forced_scandoubler=1. With that setting, the main mister menu, and all the console cores I tried, used 640x480@60. Computer cores were more varied, s...

Could I have two primary partition drives, for example. It should work. I vaguely remember having two IDE drives at one point, both with primary partitions (and both set as active), and, I think, depending on which one I had hooked up to IDE-0 was the drive that the computer used as the boot device. Pretty sure this was in the days before you coul...

I think extended partitions were only needed when the physical drive was larger than the max partition size.

To that end, I think using VHDs that fit into single partitions, and using primary partitions on all the drives would be simplest.

Some light reading on partitions: https://www.rigacci.org/docs/biblio/online/firmware/fdisk.htm https://www.win.tue.nl/~aeb/partitions/partition_types-1.html IIRC , DOS 3.3 could only have up to 32mb partitions (FAT16). For example, if you had a 80mb hdd, you could have a 32mb primary partition (C:), but then an extended partition for the rest of t...

Nice. I like the idea of the inward facing USB.

video_mode=1600,64,192,304,1200,1,3,46,162000 That matches the tinyvga.com listing. It might help to see the rest of your mister.ini. Still, not super good looking. Certainly not the poor-man's PVM that I have heard tales told about. I am sure it is my error and general in experience. Any advice is appreciated. When running at 31khz, I think you h...

I would be a bit surprised if the position was (scaler) video mode specific. For example, some (all?) of Jotego's cores have h-pos/v-pos adjustments for analog video output. That leads me to think any position adjustments for analog video might have to be in the core itself.

Timing info from cm751__superscan_751__19_crt_display.pdf, p.8. Video modes in mister use pixels/lines instead of us, however. Microprocessor-based preset functions can store 26 sets of geometry settings including the standard settings. The following industrial standard settings have been preprogrammed by the factory. No. Video Mode Name Horizontal...

Is this anything like some game gear devs leveraging its blurry screen? For example, the shield power up in sonic 1.

Tried out the core a few hours ago and played through level one of c&d, wof, and punisher. Had to retry a few times to get punisher to load, but that could have been the usual occasional weirdness of changing out cores. Noticed a bit of gfx glitches (sprite / background priority?), but nothing major.

My guess is that it would require tighter VGA timings before we could get Second Reality displayed at 60hz without any audio/video desync. I found a writeup of the code from 2013 here: https://fabiensanglard.net/second_reality/index.php The author mentions a bit about the demo using a simulated (Amiga) Copper in § Copper: https://fabiensanglard.net...

Went back and retried the demo with ao486 vsync set to variable and the audio/video are now synced.

Tested with core 20200922 and ms-dos 6.22 and got desynced audio and video.

There is a discussion on Freesync over here: viewtopic.php?f=33&t=1491

On a open source "game recreation" project I used to be involved with, Youtube videos were sometimes sourced for reference (source of truth). A quick search on Youtube, for xevious arcade and for galaga arcade, shows some videos of people playing on arcade cabs (possibly original h/w). It might be worth taking a quick look there for compa...

There is an option for a full size keyboard mentioned in the video: https://youtu.be/wmXbRdR733Q?t=1447

BVM F-Series look like 15khz (240p/480i) only.

If I understand correctly, you can use the video filters with vga scaler. An appropriate filter could possible improve the clarity of a downscaled image. So far, with fixed geometry screens anyway, I have gone with one of the gaussian sharp filters when I could not get integer scale to enable scanlines.

My hazy memory was my ISA sound blasters were all IRQ 7. So I was a bit surprised to see IRQ 5 for ao486.

The Domesday Duplicator / ld-decode projects may beg to differ.

Thanks for this!

Nit: King's Quest I (1990) was still EGA, although higher res than the original, unlike the other Sierra VGA remakes.
