I've measured the time (as displayed when pressing Tab), and there's only slight time dilation (about 2 seconds per minute) on Core i3-3110M with DOSBox (max speed). This is hardly noticeable during play. Are you experiencing faster speeds? I *may* be able to fix this and compile a new exe (based on …

Who knows? But bit 16 was later used for the WP (write-protect) flag in 486, so it certainly could be used for PG too.

It would be much easier writing your program in DOS than in Windows since you wouldn't have to deal with Windows API calls. I beg to differ. Programming sound and graphics in DirectX for example is easier than dealing with hardware directly on DOS. Plus the same game (when written correctly) will …

I don't know how to do it *easily*, but if you can run it in DOSBox, then having DOSBox source you have pretty much full control over what the program does (e.g. extend DOSBox to emulate that display)

Do games now have some sort of hybrid system where the less your video card is up to the job the more the CPU takes on, and the option is just not needed? No. In most modern games, if your card is not up to the job, you are "sorta out of luck". You may try running the game in lower resolution, turn …

More specifically, it's a set of patches to the sourcecode of original Microsoft NTVDM from NT4 in order to work on 64bit Windows. This is a serious problem. Eventually, all of Microsoft's code would have to be rewritten from scratch.

Yes. I don't even bother with those boot menus. I just have it always boot to DOS, and if I want Windows, I type "win". It's faster than selecting from the menu. :) Maybe, but you may want a really different configuration for DOS and Windows (e.g. CD-ROM driver, which you don't want to cripple your …

You need special cases for 1.0 and 0.0, so that 1.0 will give you full volume exactly (and not almost full due to rounding errors) and 0.0 will give you silence, instead of some theoretical -inf dB that may be still audible in practice.
