Suppose you had two Sound Blaster cards, one 8-bit (Sound Blaster Pro 2.0) and one 16-bit (Sound Blaster AWE64 Gold) in the same system, would they work correctly? Here are the resources used by the 8-bit card: I/O 220, IRQ 7, DMA 1 Here are the resources used by the 16-bit card: I/O 240, I/O 330, …

a) Many PC games "screwed up" the sounds of the Roland synth. Or more precisely, some games didn't initialize it properly when you run them. This meant that many games would sound completely wrong with LAPC-1 if you had played some other game just before it. The only way to cure that was to switch …

Is this a general request or would you like to try out the patch? What patch was that? How does it work? I have a Sound Blaster 1.5 with CMS upgrade sitting in my rig just waiting for that happy day.

I'd be happy if DOSBox would allow me to use true OPL & CMS chips. Could you dump the s3 bios? I got several non-s3 ones working in dosbox (elpin, nvidia, vgabios, phoenix iirc) but never found "the real thing". I dumped IBM's VGA BIOS, mainly because the card used an EPROM and I wanted the option …

As far as the MT32 goes, after mucking around with MEGAEM back in the day and Munt more recently, I decided to get the real thing. I can't see much point to an LAPC or real MPU401 though. Once you go native MT-32, you generally don't go back. However, those few who only have an LAPC-I would not …

Actually, I prefer video emulation from a quality standpoint if you are using a good LCD monitor with a proper resolution and DVI-D input. Voodoo 1 Glice, which generally used a 640x480 resolution, looks much better pixel-doubled to a 1280x960 resolution within a 1280x1024 LCD display and digital …

One of the things I am trying to do is to close the 16/32bit Windows hole. This includes games that will not run on 2000/XP, either because the hardware is too fast or the operating system is incompatible with the game. On the other hand, the game is too demanding for DOSBox or requires/supports …

The cunning plan here is to build a system that can properly run all DOS and Windows up to Windows 98SE/ME but not including 2000/XP/Vista. Naturally, give the huge differences in games that ran early in DOS's lifespan and games that ran later in Win 9x's lifespan, high end hardware will be required …

One of the best features of DOSBox is that its CPU emulation is so flexible, you can always find a right speed for the game you are using, (unless it demands a 4.77MHz 8088.) What I would do is to transfer only the CPU emulation to Windows 9x as a slowdown method. It should be able to easily reach …

Sometimes I wish for less emulation from DOSBox. For example, if you have a true Sound Blaster, Gravis Ultrasound or Roland MPU-401 unit inside your computer, it would be wonderful if DOSBox could utilize them directly rather than through emulation. The same goes for a good video, compatible video …

Suppose for a moment that you have system. This system has real ISA slots, uses real Sound Blaster, Ultrasound and Roland MPU-401 cards, has a fast, compatible 2D PCI card like the S3 Savage with a 3dfx Voodoo accelerator in reserve to a Geforce Ti 4600 (for hardware T & L.) The case has a real PC …

Actually, DosBox does nothing to help and only a little to hinder the output of MIDI bytes to the host operating system while in UART mode. Therefore anyone with a rev00 MT-32 Roland synth (ROM version 1.0x) will have buffer overflow or checksum errors unless the particular application, game or …

I wonder whether any consumer based computing product can truly boast 64-bit addressing space. That is 16 exabytes of memory addressing space, a truly gargantuan number. Just remember it took at least 15 years for the 32-bit addressing space, first introduced (1985) in consumer-level hardware in the …

Actually, in the DOS world, there are two forms of 16-bit digitized sound, those devices that process the sound in stereo, which include the PAS16, SB16, WSS, ESS, and the GUS, which mixes multiple channels in hardware. 16-bit @ 44.1kHz is the best audio output that you will receive from any ISA …

I am thinking that it is irrelevant for games whether an ISA card supports 16-bit digitized audio. No DOS game would have the space for 16-bit digitized sound unless it came on a CD. A DOS game that supports redbook CD-Audio does not need the help of a sound card to output 16-bit digitized audio. …
