Re: AO486 compatibility list

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

Re: eXoFlynn Top 300 DOS Pack Updates and Support

Thanks for this!

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

Re: Thermal management

Cyclone V datasheet: https://www.intel.com/content/dam/www/p ... _51002.pdf

Absolute min/max operating temperature is listed at -55 to 125 deg C.

That is for the FPGA chip itself. Other components on the DE10-Nano may not be so forgiving.

Re: A case for 5x vertical crop in 1080p mode.

I have an possible use case for custom cropping. The vertical scroller CPS1 games appear to be outputting a vertical resolution (per the mister video info OSD box) of 393x224 instead of the expected 384x224. If I could crop off those extra pixels, I could possibly get 2x integer scaling at 1366x768 ...

Re: Fan Supposed to be Running?

If the fan is finicky, it may need 5v to startup. Try the 5v jumper position if it is on 3.3v (or missing entirely).

Re: Vertical Scanlines for integer scaled 256x224?

If I understand the current screen resolution logic correctly, I think integer scaling is only based on the vertical resolution, with horizontal resolution being calculated per the aspect ratio. I think you would probably need an option for the integer scaling to be based on the horizontal resolutio...

Would one also need something like Legaxy Pixels' MIDI board to be able to hookup to the PI-MIDI (hypothetically at least)? Despite owning a number of aftermarket sound cards over the years, ...

Re: Scale Filters - Possible to add more?

This may be something worth doing on an external upscaler such as OSSC, rather than MiSTer. It's a pretty niche need and it could benefit other retro devices, so it may have a bigger audience there. OSSC Pro , perhaps. Depending on how close of a CRT look it could get, while still having low lag, w...

Re: Non-square pixels, is changing the PAR possible?

To borrow from Nvidia control panel settings, it sounds like you would be looking for "Full-screen" scaling, instead of "Aspect ratio". Or perhaps, the ability to specify what the aspect ratio of the target display is. Not sure if that would actually be different in this case (from a "Full-screen" s...
