Here is a post about single player Q2 levels: https://www.quaddicted.com/forum/viewtopic.php?pid=1302#p1302. Many of them don't require a custom game dll file (typically win32), which is fortunate since I've yet to find one with accompanying source code. Some of these sites have a lot of files, but …

I agree. Those DXE_EXPORTs must be in one of the mods. I just ran a difference files against an older custom build and noted 3 exports which I didn't have, although the build was missing the expansion packs.

Attached a test patch to allow for a minimal q2dos build (USE_GAMESPY=USE_CURL=USE_OGG=0). Most of the lines in the file show code regions for potential placement of definition lines to make sure that gamespy/curl/ogg features do not interrupt the build process. Also, included some line changes …

I show a pagefault where the attached patch is applied (djgpp 204/gcc45), but there is no error otherwise. I wonder whether the array is read-only where placed outside the VID_MenuInit function, combined with compiler specific behavior (since only my version presumably has the issue).

Thanks! I'll definitely use the update and try out the static build.

Brilliant. At least the cause is known. It's nothing more than the mod is not meant for single player mode, or at least nothing apparent from another part of the code. Thank you, too, for debugging it! Edit: A new mTCP is available! (mTCP 2015-07-05) (new mTCP package)

That's very good of you. I am putting "abort()" commands in the init as you suggested, but probably avoiding the single player is the simplest, given your know-how. I would have to figure out the structure of loading more than I know at present. :) Edit: verified that the error occurs before "void …

It must have the video file named "ntro.cin". I wonder if my LFN support is not so good, as you noted! Edit: I changed ddayintro.con to ntro.cin and it showed video and no error. Edit2: I'll try the g_save.c method next since it showed the error after video.

That's very helpful, thanks again. I also just saw this post with a possible file (which I'd prefer to bypass altogether!): http://www.ddaydev.com/forum/viewtopic.php?f=7&t=8476.

I agree on the emulation. I mainly reported it for information only. I'll follow both your suggestions on the other thing. I also appreciate the updates to q2dos! I tried them today, including the mouse changes and such.

Thank you for the suggestion. If the video file doesn't fix it, then I'll definitely boot up VS6.

I think there is a hint to the issue in dday. I ran dosbox at very slow speed with "developer 25" (as you showed me earlier). The issue occurs before a msg about "video/ntro.cin" missing. I added an empty file by that name and it exits about a read error instead of a pagefault.

The aspect looks very good on all intended modes. I ran tests to determine the source of those fpu under/overflow errors in dosbox while "stress testing" q2dos and a custom test build (repeated game mod loading/unloading with maps). It's very likely that the fpu emulation of dosbox (given my …

The modex should be faster, aspect friendly, and as compatible with other video cards as 0x13? Also, it won't be any faster because it does have an extra 12800 pixels to draw. You can see this by setting 320x200 and 320x240 LFB if the card supports it. And with the planar modes Abrash came up with …

That's right, "The Guide -> DOS" was originally intended for all sorts of discussion of NTVDM compatibility hacks and game patches and whatnot, back in 2002. It was "PC Emulation" that was intended for actual emulator discussion. But after several years of having absorbed the DOSBox support forums, …

I didn't know that was available, the static build for Windows. I'll give that a run for sure. Thanks.

That's very good news. With all your work on q2dos, I think I'd run it on Windows, too, over any other port. Even if just for stability, given all the debugging work. That's interesting on the video versus cpu bottleneck in performance. The banked modes was also useful in the path to modex, I think …

I bet it runs fast in PCem, too. Many users try the different video emulations/bioses and they'll have a chance to test their different system configurations.
