Re: vgaonly - 16-bit RGB?

16 bit must have been faster back in the day maybe? But seems like you waste a lot of time later during the blitter stage to convert it to 32bit again there.

Well dosbox used to include mame sources of dubious copyright legality and I thought why not just go for the freshest mame sources now that they changed their license. The mame implementation for the SN76496 contains all kinds of implementation with different noise tap inputs. I wonder if any of …

it seems like a nice enough kit to just try out for a bit. Wonder how many opl2 chips he has left 😀

Nice test suite, most stuff seems to pass except for the typical looping rotates, although I doubt that would cause any problems with programs. Nobody is bored enough to make task switching, security and vm86 tests I guess 😀
Re: DOSLIB Sound Blaster speed tests: What does the card *actually* do with the sample rate?
Posted on 2017-10-26, 07:04
oh that's a pretty nice way to measure things. sloooow samplerate to make it more obvious and maybe also time when an irq occurs.
Re: DOSLIB Sound Blaster speed tests: What does the card *actually* do with the sample rate?
Posted on 2017-10-23, 08:19
With such a large fifo you'd imagine it would start the IRQ while there's lots of data yet waiting to be played in the fifo. I always thought you'd have more noise from single cycle dma but you don't really notice is that much. Although the dsp will just keep playing the last sample as long as the …

Posted on 2017-10-23, 07:48
Slightly offtopic but seeing as you're doing sountblaster tests I've wondered about the amount of processing time and buffering the soundblaster DSP has. How soon after a sample is read through DMA does it appear on the output. Is there some small fifo in there to allow for a bit more output to …

Well I gave it a try and the engine works decent enough. But ofcourse there's not much to play and the controls feel a bit floaty, I'm also missing some sort of status bar but ofcourse limited resolution, maybe use 320x240 The character centering is a bit annoying as well with you walking too far to …
Re: Do you play games off of their CDs?
Posted on 2016-01-13, 07:21
Just tried it again and Daemon Tools works fine with cue/bin with Loom on my win 98 se with sb16, since that game only does cd audio without soundblaster. If games use regular soundblaster with cd audio you'd need an SB Live or something that could do soundblaster emulation and still have windows …

I think you can get a sata dvd emulator thing with usb for the xbox 360, ofcourse only to run your legal copies, but should try hooking it up to a pc sata port.

I hate the noise cd drives make so I'm pretty much only using cd images SHSUCDHD allows you to mount cdrom images under DOS, quite liking that on my old dos machine that just has a bunch of iso images on a secondary drive. Mounting images under win9x allows cd audio as well and that runs most of the …
