Stop worrying about files, because it's normal for a game from this period not to copy all the files, only the necessary ones. The question is: does the game run?

But it would not install the game right. What does it mean "not right"? Does it install but doesn't work, asking for CD? Open Registry Editor (regedit.exe), go to HKEY_LOCAL_MACHINE\SOFTWARE\lucasarts entertainment company\jediknight\1.0 and set the following values pointing to your CD-ROM drive …

Re: How does an x86 CPU swtich from 16 to 32bit mode?
Posted on 2017-01-15, 18:30
So does that mean that I have to manually write 256 pieces of code (one for each interrupt, as any one could be called at any time, without warning, by the underlying system), Technically yes, but most of them could be simple stubs, and one piece of code can be shared by multiple interrupts. and …
Re: Has anyone ever made a soundfont (.sf2) in Vienna ?
Posted on 2017-01-15, 18:21
In the old days, having only AWE64 Value (and no possibility to find memory upgrade for it) I used to make an .sf2 for every MIDI file that I liked - using ROM bank as a base but adding particular instruments (mostly) from 4 MB bank making sure it still fits within limited memory of AWE64 Value (was …
Re: Questions about Turbo C and far pointers
Posted on 2017-01-11, 12:43
unsigned char far *FarPointerToByte = MK_FP(segment,offset); FarPointerToByte=FarPointerToByte+1; What about incrementing the offset, and doing MK_FP again? This may (or may not) have performance penalty, though. But try it.
Re: Why is 32bit Protected Mode not working in DOS Box?
Posted on 2017-01-11, 11:38
;Switch into 32bit protected mode by doing a far jump jmp 0x0008:FinalizeProtMode Shouldn't it be jmp dword 8:FinalizeProtMode ? If I remember correctly, you need to fill all 32 bits of EIP, so the jump instruction should have 0x65 prefix to force 32-bit addressing. Otherwise you're writing only to …
Re: How does an x86 CPU swtich from 16 to 32bit mode?

But how to you set the mode? Protected vs Real Mode is set by a specific bit in CR0 control register, then by a far jump to the new code. 16-bit protected mode vs 32-bit protected mode is set by a specific bit in segment descriptor. You switch the "bitness" by doing far jump (that is, with selector …
Re: dgVoodoo 2 for DirectX 11
Posted on 2017-01-05, 16:38
The only solution would be trying to add a fix in dgVoodoo, if possible (I didn't check that game yet, so I don't know). I think it might work if dgVoodoo allowed to specify different scaling modes for different resolutions. Jedi Knight uses hardcoded 640x480 in menus (where the mouse problem …

Why is the screen in Jedi Knight always stretched to the whole screen (16:10) instead of 4:3? Without dg the screen is correctly pillarboxed which is what I want. In other words, why doesn't dg respect the setting in display drivers? I'd like to play in 1280x960 without any resolution magic or …

fullresolution=1024x768 Most probably your monitor stretches 1024x768 to its native wide-screen resolution, which is not what you want most of the time. You may be able to change that in your gfx driver configuration.

4Mhz vs 266Mhz Speed can be adjustable. ISA only vs VLB vs PCI No real slots are needed. no FPU vs FPU vs MMX Of course FPU + MMX. Those won't hurt any non-FPU and non-MMX game.

You can check the header to see if it's 16bit 32 and 64-bit EXE and DLL files have almost invariably this text near the beginning: This program cannot be run in DOS mode. and the letters PE shortly thereafter. 16-bit ones typically had: This program requires Microsoft Windows. and letters NE .

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 …
