Re: Why don't some cores support analog video?

If you're using a lot of PC cores, running on a CRT TV is just a losing battle. You can enable the scaler for 31KHZX cores to downscale to 240p and get it to work, but it doesn't look great. MS DOS games from ao486 are 1:1 and look fantastic on a 15khz consumer CRT TV when using modelines. Same for PC 8801 (which actually has native 15khz, just no...

Re: Why don't some cores support analog video?

Thanks for the replies. The x86000 *does* support analog video, however it supports its original multisync monitors that could handle 15khz, 24khz, and 31khz resolutions, with 24khz being an oddball resolution not really seen in the West outside of some arcade screens. From what I can tell, the D14H5U supports 15khz (240p/480i), 31khz (480p), 33khz...

Why don't some cores support analog video?

In a thread troubleshooting VGA -> composite video without scaling: https://www.atari-forum.com/viewtopic.php?t=35062 Sorgelig mentions: As for other cores - it depends. If your TV is NTSC-only then you will have problems with some cores. My own setup is VGA -> component on a BVM D14H5U (which also supports PAL signals). I noticed this is indeed th...

Re: PC98 Core

* Relying on VFIC seems prone to breaking in the future. Someone rewrote a couple conversion tools in Python: https://github.com/barbeque/pc98-disk-tools * We can't go directly from HDM to D88 using these tools. However, going from HDM to FDI then using pgimeno's FDI to D88 script (http://www.formauri.es/personal/pgimeno/misc/converters.php) might...

Re: PC98 Core

I'm a complete newbie to the PC98 and really to MiSTer in general. Here are some notes on the thread, and the setup that worked for me. I don't like BBCode so the notes are plaintext. ===== CORE SETUP ===== * I used Mr. Fusion for my SD setup: https://github.com/MiSTer-devel/mr-fusion * The root of the SD card contains a _Computer folder. This is w...
