Yeah, for me the server is the show stopper. I also understand the reason why, but I don’t have the space for a (second) server besides the (Linux, but closed) NAS that I use. A Synology plug-in for EtherDFS (or NetWare) would be great, but I guess such a thing is infeasible.

I often find the monitors that support 70 HZ are often the lower resolution ones because they just have less pixels to push around. For anything above 1024x768 it becomes less likely to support more than 60 Hz (but they do exist). For me the most annoying thing about digital screens is that they …

I have a GeForce 2 MX and a ET6000 card working together in Windows 98 (if I want to). I do not use it like that unless I want to compare monitors. I can just boot normally with AGP but I think you do have to connect a monitor before you boot or Windows will not correctly detect the output. Back in …

To my eyes the response curves of most CRTs are different than modern displays that are all tuned to give benchmark perfect results. Also the primary colors on CRTs look different then modern calibrated displays. Not always for the better, but a good CRT with (still) good phosphors has a particular, …

But if I set the volume of my …

The problem with IRQ 11 is that some DOS extenders don’t like those high IRQs. Also, some audio libraries don’t play nice with IRQs > 7. For the GUSpnp there was a tool to patch games to play nice with IRQs > 7 but I don’t know if it also works for other GUSes.

I am also very glad with this patch. I use a GeForce 2 MX and it can’t do 15 bit video modes and lacks the low res modes 400x300 and 512x384. Now I don’t have to swap video cards when I want to use those resolutions. The only minor thing (but it was probably assumed) is that you have to register the …

To add a little to the great explanation of Tiido: you asked if a tracker just outputs PCM to the soundcard. Well, that is entirely up to the software and popular software from the early 90’s used the hardware of the GUS (and later AWE) to reproduce the music. That was in the early 90’s much higher …

Those black bars on Jazz Jackrabbit are normal. It uses square pixels because that video mode is based on a 320x240 video mode.

You need to create EMS memory, a lot of it, and free as much low memory as possible. So only load drivers that are needed for Impulse Tracker, because once you enable EMS the page frame will consume a lot of upper memory.

I have no need for this myself, because I have an original GUSpnp card, but are you aware that there is also a .mmx driver for the codec? If you CPU supports MMX it provides much higher quality mixing (the default mixer is not very good) and it supports the resonant filters of the .IT format.

Not 100% either. There were a few games that supported GUS natively and that card used PCM samples that are processed (pitch, volume, position) on the card. It did this together with MIDI playback. The AWE 32 was capable of the same, but I don’t know of any game that uses it to process sound effects …

Adlibtracker 2 doesn't even work with only the sound blaster in. It must need some fancy memory settings or something. I'll figure that out another time. Every other opl program works and everything to do with the gus works so the hardware on both cards is good :) Adlib Tracker 2 is very speed …

I grew up in analog PAL territory. Every brain cell that was sensitive for this flicker has already died off years ago 🤣 But I tend to use my CRT mostly for the 70 Hz low-res stuff as most 60 Hz modes display okay on my LCD monitor.

What IRQ is your GUS on? My GUSpnp has always been on 11 and FastDOOM doesn’t like that. If you have UNISOUND on your system, you can try set your GUSpnp to IRQ 7 by doing the following: SET ULTRASND=port,dma,dma,7,7 (the first 3 values you should copy from your AUTOEXEC.BAT) UNISOUND On my system …

Yes, and then it is OPL music. The underlying data is sometimes midi (not really with DOOM) but the better games had specific data for OPL and General MIDI or Sound Canvas (those referring to the SC-55) because they are so different that using one piece of data for both would lead to a compromise ( …

Interesting that you mentioned the IRQ… I forced my AWE64 temporary to IRQ 5 with UNISOUND (yes I use it too) and the bug doesn't happen with that. I have little knowledge about the Apogee Sound System, but it would be really, really user unfriendly if it only works with IRQ 5. There is very few …
