Re: Best CGA & Hercules games

By the way, do you agree that it's a shame that the developers of the HGC never bothered to implement a graphics mode that supported both brightness levels for individual pixels, like it did in text mode? I do agree. HGC already had 64 KB of RAM, enough for 720x348x2bpp, so implementing such a mode …

Re: PCI Bus Mastering in DOS

AvalonH wrote on 2020-03-24, 19:08: 1994 Mach 64 PCI - supports bus mastering 1993 Mach 32 PCI - supports bus mastering Interesting... Bus mastering is useful when the card pushes data to the host's memory, eg. in disk controllers, network adapters, frame grabbers... But why would bus mastering be …

Re: Best CGA & Hercules games

I don't think anyone mentioned Korean Dungeon Boy yet. Some of the cleanest, well drawn Hercules gfx you'll see this side of the Milky Way. Fun too! (kind of important I guess) That screenshot is 640x400 - so it must be using the undocumented 640x400 interlaced mode. Fascinating, I didn't know …

Re: Best CGA & Hercules games

Yes, Popcorn is very fun to play, in terms of gameplay it's one of the best Arkanoid variants ever. However, technically, there's nothing impressive about it - quite contrary, it pretty much requires 8088@4.77 and true CGA, which would be perfectly OK in 1983 - but this game is from 1988!

Re: Video playback on a 286? - here's how to do it

American Laser Games was banking on that back in the day. They've tuned their codec and data for 1x speed and 286s for their DOS ports. Most of the video kept being half-resolution in lots of chunks. It's noticeably visually worse than even other 1993 CD-ROM FMV games. You mean this, right? - …

There's also "8088 Domination" - 640x200x1bpp. Anyway, a 10 MHz 286 can play video pretty well, provided it's stored in some uncompressed format - https://www.youtube.com/watch?v=wraAawslLKs And the fastest 286 machines run at 25 MHz …

Re: SVGA minimum RAM?

I though 800x600 was only possible with 16 colors (256 KB) but I also though that 640x480 256 (512 KB) was possible, so I am wrong in one of them (or both). You may also be perfectly right. I've seen at least one 512 KB card that can't do 800x600x256. I'm not sure why - perhaps not enough video …

Re: SVGA minimum RAM?

Anonymous Coward wrote on 2020-03-09, 15:31: Let me guess...53Hz interlaced. According to my monitor, 29.3 kHz / 45 Hz. Definitely non-interlaced, and I even doubt that plain VGA can do interlace.

Re: SVGA minimum RAM?

Anonymous Coward wrote on 2020-03-09, 10:42: Can the PS/2 Display Adapter show 800x600? Yes, plain VGA can be tweaked into 800x600, but at some abnormally low refresh rate.

Re: SVGA minimum RAM?

I had a 256kb SVGA video card 800x600x16 was possible Also had a windows driver for 640x400x256 which I’m told is abit odd. Always wondered why more cards didn’t support that out of the box? Actually, many SVGA cards do support 640x400x256, via built-in BIOS mode. Even more can be made to support …
