Executing DOS commands generates a debug log message such as "EXEC:Parsing command line: blah". When a program shells out to COMMAND.COM to execute a command, a blank line is sometimes displayed in the debugger output view instead of the message; however, the message is always written to the log …

Well, it's not the only way, its just the usual way. If you aren't hitting a "BPINT 18" breakpoint in the debugger, there are a few other things to try: 1) If you're using dynamic core, switch to normal core, because breakpoints don't always work on recompiled code. 2) Set a breakpoint on the memory …

The addon was released as freeware by 3DRealms, and is available (with no support) on their FTP server. Wolf3D is crashing because the external menu program tries to rename some files using wildcards, which DOSBox does not support. You can work around the situation by using the 4DOS command shell, …

There are several Cinemaware games that suffer from the problem, including all of the TV Sports titles. The games might be relying on timer behavior (as it relates to speaker operation) that only existed in early PC hardware, but that hasn't been proven yet. I reported the issue to the DOSBox devs …

Seems there are some competent emulators for the system already, but would be easier to work with that stuff if you have a decent grasp of Japanese. 😉

That's a possibility, but the program is using many more values for AH than are documented there. It is also using a bunch of low port numbers that don't make sense for a normal PC.

The code sets registers, including what appears to be an AH command code, prior to calling INT 18h, and stores register values to memory afterward, acting very much like it expects some kind of "service" to be active there. Can't find any online docs about known uses of that vector except some old …

FYI, DOSBox displays that message and quits when INT 18h is called. On some BIOSes, INT 18h activates ROM BASIC, which might explain that other message about DosBasic. Anyway, dunno why it would be calling INT 18h... maybe it's supposed to be hooked by a TSR or device driver that hasn't been …

You are trying to configure and run the game from the CD. You must install it to the hard disk and run it from there. Mount a C drive, mount your CD as the D drive, and then install from D to C. Then you can configure and run the game from the C drive (keeping the CD mounted as the D drive). This is …

I guess it wouldn't be Jungle Strike, since that's so closely related to Desert Strike. Have you tried using the game browser on Mobygames and filtering for Isometric Shooters? You could then narrow it down further for Windows or DOS and specific years. Based on your description, "Fire Fight" and " …

The comment on write mode 3 in vga_memory.cpp states that the host data should be rotated, but it's not being done. Adding the rotate (copied from mode 0) appears to fix the corrupted text in the game: case 0x03: // Write Mode 3: In this mode, the data in the Set/Reset field is used as if the Enable …

The driver creates a device named "ST"; might not be well supported in DOSBox even if you use a program to load such a driver. DEVLOAD.EXE hangs trying to install it. However, I tried the game when booting MS-DOS 5.0 in DOSBox, and the device driver and Smooth Talker TSR work OK that way; so it …

DOSBox's internal COPY command does not support copying all files from a source directory unless \*.* is explicitly appended to the filespec. Real DOS assumes *.* when the source filespec is a directory, and game install batch files might use this (Bram Stoker's Dracula is one I know of that does). …

The gfx corruption occurs with the ega,vgaonly,and all svga_xxxx machine types. However, it also happens when running the game in the WinXP NTVDM, so it may be that the EGA version of the game is broken. There is a workaround: do not move the mouse pointer at all until you close the map (pressing a …

Actually, there is a way to get CD support in booted hard disk images (kind of) using an image big enough to hold the contents of the CD(s) and the FAKECD/FAKEDR utilities . Wouldn't recommend it to novice DOS users, though. I've had good level of success with it on a number of CDROM games that I …

It's poking around for Novell NetWare, although I don't know what level of network support it requires. It's also doing absolute disk reads with INT 25, and that's not going to work in DOSBox unless you boot a real DOS. This appears to be a commercial app, and if so, shouldn't be posted here.

The game wants the base IO address of the GUS to be 220 (gusbase=220). 220 is the default base IO address of the SB in DOSBox, so be careful not to overlap by either disabling SB (sbtype=none) or use another base address for the SB (e.g. sbbase=240).
