If ReactOS's NTVDM uses an emulated CPU core than how is it different from DOSBox? I have no problem with ReactOS's NTVDM, but I am curious. First of all, our NTVDM uses our own (well, Aleksandar Andrejevic's own :) ) emulated CPU (called "Fast486"), which is currently an interpreter-type CPU emula...

Okay, so I'm a programmer. How should I let people know my program is compatible with ReactOS? Should I use the major build, or the nightly build?

I think I was trying to get at that it will be just as good as Windows, if not better, but doesn't have the cost.

Will it's official, ReactOS is Windows without the cost or something... Not sure where I was going now.

I was thinking, some of the cheaper laptops and computers come with either FreeDOS or Linux due to them not having to pay a licensing fee to install it. Does anyone think that once version 1.0 comes out that ReactOS might have a similar use?

This is because ReactOS runs DOS applications on an emulated CPU core, rather than natively on the host CPU, and emulation has a lot of processor overhead. (Running it inside a VM is even slower, an emulator within an emulator.) For the vast majority of old DOS programs this is totally fine because...

DOS media player shouldn't require much RAM, and almost certainly not more than 16mb (the practical limit of DOS extenders of the day). But I've noticed that even for trivial tasks, ROS sometimes uses 100% of CPU and takes a long time to get past it, such as loading a file larger than about 32k int...

@MugenFighter: yes, WOW16 is related to NTVDM (with a bunch of wowexec.exe/wow32.dll stuff under Windows), but seems nobody is working on it yet (however if someone if willing to implement it, we accept patches :D) I can't implement it, but if anyone is willing to, here is some info on a Win16 emul...

QV Pro 2.61 (a MS-DOS/FreeDOS media player) starts up and attempted to play a video, but the result was that it skipped almost all frames and took a couple of seconds to update the frame. Basically a normal video ended up looking like a slide show of random frames. Minor win I guess. Edit: It might ...

ENIW Now in Windows

What about a Win16 subsystem? Or would that just be part of the NTVDM subsystem?

Edit: If ENIW gets finished, would it work with Windows XP?

ReactOS equivalent of WSL.

Sorry, I just googled it.

I just got C64 Forever and Amiga Forever to run with the same configuration (with CD/DVD images instead of floppies of course).

A couple of years ago I posted on the Epic Win Thread that FreeDOS 1.0 could boot up with ReactOS 0.3.9's NTVDM. Is it possible that such a feature could help the users or developers of ReactOS? Also should such a think be tested more?

Okay, thanks! Guess I'm only mostly an idiot [just kidding].
