hmmm, no TEXTUREBUFFER and COMBINE support. Well, yes. There are all sorts of undocumented obscure extensions. I don't know what are they for and how they works exactly. I have guesses but that is not enough to implement them. Maybe raking over Glide3 driver sources would help.

I've tried F22 TAW. It always crashed with stack overflow when I entered a single mission. This program has 64k stack. When I hacked the exe to raise the stack reserve/commit to 1MB, it seemed to worked fine, altough didn't experimented with it a lot.

As far as I know, buffer pointers remains unchanged on a Voodoo hardware, so pointer B is always points to the backbuffer (but I'm not 100% sure, should have a look into 3Dfx specs). In dgVoodoo however, I let the pointers get swapped because of optimization reasons except when a locked buffer is …

Ok, great! Tomorrow I will make a new build and send it to you. Release the code...? Hmm.... But then I would have to release all my libs dgVoodo relies on. 😁 I will deliberate on this. Edit: set -> send[/u]

Hi All! It's been a long time I posted here... :blush: (to be clear, I was trying to fix the problems mentioned in "Tips and known issues" from the dgVooodoo2 README - perhaps the stride limit needs to be removed from dgvoodoo?) Well, as far as I remember, I run into 2 problems with lfb access ( …

Hi Nil, I haven't tried dgvoodoo with Blood MapEdit, but dgVesa has support only for modes with linearly mapped memory (apart from VESA-banking). So that, all 16 color modes (4 bit, 10h, 11h, 12h and even 8 bit x-mode 13h) are out of its scope, unfortunately. I didn't take it as a big problem, as …

(and thanks to my ninja-like reflexes that allowed me to sc this thing...) :happy: Well, dgvoodoo for DOS can work in two modes: - VDD mode: don't care what it stands for, the point is, in this mode it's enough to have and use glide2x.ovl and glide2x.dll (and dgVesa if u use that) in a copy-and- …

Just a thought after a long silence... I don't really know what the situation is as to glide wappers nowadays. Are they still used by the retro gamer community, and would be cool to develop them, or, theirs era is getting over now with win Vista and 64bit systems? Speaking about dgVoodoo and having …

Well, VESA works with an emulator like dgVesa, VDMSound works from command prompt. Sapucdex doesn't work because MS have dropped the support of playing CD audio at IOCTL level. 😢

A veryveryvery late respond again, don't know if someone is reading this. :dead: So, I've just had a look into the source of dgvsetup and found that the vertical positions of those buttons (actually the window they reside on) are hardcoded. What I don't understand is that the main setup dialog is …

Sorry for the late respond, so: So in the end what do you think of the OR act ? Was that alpha tinkering ? Or is your explanation different ? Yes, I think it's a kind of tinkering. Maybe the original 3dfx hw worked in a similar way you tried for some reason (and it's not tinkering after all, but a …

but the shaky rationale for that would be, with an OR I will do no harm to the 24 bit part, if I set bits 24 through 31 maybe I'll have a makeshift 7f value for a in argb. I saw storms of 24 bit color values coming, what if I sorta append 7f to them and enjoy the show ? Hmm, now I'm getting the …

Well, here is how dgVoodoo handles TR1-problems: Missing shadow: When I first tried to get TR1 to work with the wrapper, I figured out that TR1 engine mostly drives the wrapper through the utility-function set, so that through the guXXX functions. All of the pixel-pipeline settings are done via …

Thanks, but I've found another solution. If I create a maximized window without border and caption then Windows treats the application as a fullscreen app and automatically hides the taskbar when that window is the active one. 😀 I'm going to build it in dgv.

A very minor issue is that any part of the taskbar which updates (e.g if a tray icon changes) shows through carmageddon in dgv when carmageddon is in a video or menu, but this is incredibly minor and not really a problem Though I believe if you were to disable Aero before running the game it …

if you use the WinXP video drivers for your graphics card in Vista 32 bit it can resume full screen capability. Could it be true then ? Would downgrading of the drivers be safe anyway, aside from effectiveness ? Yes, it's right, Vista can work with old XPDM-class drivers too, but you don't have DWM …

Well i thought even in long mode temporarily switching to that compatibility mode is possible I think theoretically it could be implemented in two steps: first switching from long mode to 'normal' mode, and then switching to v86 mode. Nevertheless it would cause too much performance overhead, would …

Do you think this (especially dgVesa and SolVBE) has any chance on 64bit systems? Unfortunately, not. Since a 64 bit processor can't execute any code in virtual x86 mode (from 'long' mode, due to * ** AMD :angry: ), I guess there isnt even any kind of ntvdm included in 64 bit windows. Must use …
