Re: Problem with using SDRAM in my Pentium MMX machine

What motherboard do you have? If it's 430VX or TX based, then you might need older DIMMs, usually 32MB PC66 do the trick.
Re: recommend a CPU upgrade for my 486 (and RAM)

As an owner of a Cyrix 5x86... I'd recommend the AMD 5x86 133. The Cyrix part can be faster than the AMD part, but it requires some luck to overclock the 100MHz part to 120MHz, compatible boards (which you have) and perhaps more importantly, some degree of tweaking to enable features and registers …

Re: Windows 95 lag spikes using sd to ide adapter
Posted on 2021-04-11, 17:07
Are you sure this is an issue with the SD card or adapter? Is DMA enabled for the controller in the device manager? Have you given "Cacheman" a try? I find version 4.1 to work pretty well for Win9x.
Re: Ultima IX issue - Lag on loading books
Posted on 2021-04-10, 09:28
I've had this exact issue on countless systems when trying to run Ultima IX. I'm afraid there ain't much of a solution, it seems to be tied to the Direct3D renderer. Perhaps you could try a Glide Wrapper such as the original dgVoodoo, I remember the problem going away when using a 3dfx card.

Well, that took a while. Sorry about the delay, didn't really have the willpower to work on this for a few days, but today I decided give it another go. I went ahead and tried something different, L1 enabled, but L2 disabled and guess what, system seems stable, I couldn't get it to hang! I pulled …

Concerning Windows 3.1x and WfW 3.11 usage, I wonder if Glenn Slayden's " TI486 VDMAD " driver could potentially be helpful? TI486 VDMAD - Version of the virtual DMA device (VxD) for Windows 3.1 or Windows for Workgroups 3.11 which, in order to preserve external cache coherency, controls the 8K on- …
Re: 486DLC cache coherency blues and headaches

Interesting. Any thoughts as to what could be going on? I'm fairly certain all issues and freezes disappear as soon as I disable both caches or perhaps I haven't been able to make it hang just yet. The exact same issues also manifest when L1 is off and L2 is on. I use DOS Navigator as a Norton …

Messed around with it for a few hours and while I can get DOS to be mostly stable, Windows 3.11 is a lot more volatile. I tried the FLUSH switch, going to take a look at the BARB one next. What an annoying thing 🙁

Hi, thanks for the in-depth post. Unfortunately, I tried what feipoa suggested as a general rule of thumb in that thread and it didn't really help any. I was perhaps looking for some more deliberate/targeted tips and suggestions, maybe from someone that has experience using said chip on this chipset …
Re: Voodoo 1, 2, and 5 questions
Posted on 2021-03-27, 01:01
It was slow, but we just accepted it at the time because we didn't really know better and our idea of smooth gameplay was very different from today. Videocards were actually fast enough, it was mostly CPUs that were holding those games back. Pair a single Voodoo2 with a fast CPU and run games from …

That 2nd pic was everywhere at the time, I remember seeing it in a magazine article pitting the GeForce2 GTS against Voodoo5 5500, but it's actually a promo shot from the cancelled Ultima Online 2.

Greetings! 2020 was a very rough year. However, if there's one positive aspect of it that I can find is that I got infected by the retro virus once again. Well, my wallet would have a different saying on that, but the free time/boredom chart showed a definite rise to unprecedented levels. In October …

I can attest to that, it has been discussed multiple times here, Deus Ex really needs a much faster processor than stated in the system requirements.

Are you using SMARTDRV when booting to DOS? Perhaps it could alleviate this stutter.
Re: Trying to find a particular NES game
Posted on 2021-03-21, 23:08
Ignoring some parts of the description, it bears some resemblance to Altered Beast which did have a (crappy) port on the NES. Perhaps he's misremembering the system and it was actually on the MegaDrive?

This is not something I have tried. Any particular reason you'd want to run without the latest Service Pack?

I've had great success in the past using the USB driver linked in this blog post. Haven't tried them in a few years, but they worked well enough at the time as I recall.

Try these , I just set up NT4 on a Pentium Pro with a Live! Value (CT4830). I also further installed the latest update that can be found on Creative's website (sblwntup.exe). Works really great for me at the moment, the only issue I encountered was a conflict that was solved by switching PCI slots …
