I heard a sound like wind blowing, but I guess it was the synth. Wikipedia has a list of MT-32 compatible games, and MM3 has a footnote that it uses the extra sfx of the CM models (LAPC-I is basically a CM-32L on a card).

Compared to an MT-32, the LAPC-I and CM-32L have additional patches that are mostly for sfx, so it's possible the game is using them. But typically you won't hear *nothing* when a game tries to use one of the sfx sounds on an MT-32, rather you hear some inappropriate instrument sound instead. Do …

MT-32 music with SB sound is working for me using DOSBox 0.74 with default config except midiconfig= to select MIDI I/O for the MT-32. I can hear Sheltem's intro speech and the in-game sfx like "kick door in" and cast magic actions. Maybe the SB isn't detected, although I haven't seen any …

The problem is caused by something very trivial, and it's exactly the kind of thing you so often run into with downloaded warez copies. The game in question is still sold by the copyright holder/distributor here and here . Perhaps you can get support from them after purchasing a licensed copy of the …

More than double-clicking, the game reacts to the mouse buttons being held down, rather than waiting for a button-down/button-up sequence to register a "click". If you keep the button pressed on a turn arrow in the 3D view, you spin around continuously. How fast this auto-repeat occurs can be …

The attached patch performs a separate search for the volume label. Could also make a VOL command with a similar approach.

I'm guessing cdrom drive/image access after booting DOS or Win9x. I think an ATA/ATAPI emulation is required to support the device drivers in DOS (e.g. DEVICE=OAKCDROM.SYS), and the ATAPI drivers in Win9x. If the OP is referring to local drive access after booting, ugh, don't know how that could be …

Various forms of BASIC recognize the keypress, but Ctrl-ScrollLock is not a generic substitute for Ctrl-Break. DOSBox does not implement true Break processing in its emulated BIOS and DOS. Not sure it's worth mentioning in the readme/manual when it pertains mostly to BASIC.

DOS mode prints 'function not supported on this computer'. Strange, MODE.COM from MSDOS 5 and 6, and the MODE program from FreeDOS work in DOSBox for setting the keyboard typematic rates. The syntax is "mode con rate=r delay=d" where r=1-32 and d=1-4.

Most BASIC interpreters and compilers will recognize Ctrl-ScrollLock as a Break, because that was the Break key on PC XT-style keyboards.

If you went by the changes to VGA_TEXT_Xlat16_Draw_Line() for vgaonly, you probably would have had less trouble applying the same changes to the commented-out text drawing routine because the code is similar. Anyway, the attached patch against current source should suit your needs. I had to figure …

Only testing bit 2 of vga.seq.character_map_select to enable/disable the foreground intensity of the attribute may not cover all possible conditions. I based it on observations of how WP 5.1+ changed the register when 512-character mode is turned on and off in its setup. It may be good enough for …

It should work with all vga machine types except vgaonly, and that could be added if needed. Changing the font patterns in int10_memory.cpp shouldn't make any difference. Edit: revised patch to work for vgaonly as well.

vgaonly and loading a video bios doesn't change it. The experiment patch I posted is only on the svga_* text drawing; with vgaonly the 2nd font table characters still display in intense foreground colors because vgaonly has a separate text drawing routine, but it could be changed as well.

The issue appears to relate to the font map select register of the VGA sequencer. When it is set so that bit 3 of the attribute indicates "use 2nd font table", then perhaps bit 3 no longer indicates foreground color intensity. Although the attached patch appears to work in this particular case, it …

If you look at the file in some editor program, does it start with "PCjr Cartridge image file", the "PCjr" part being particularly important for DOSBox to identify the file as a PCjr cart image.

BOOT is a command, not a config property, so the = sign is not needed (and gets included in the filename, if that could be considered a parsing error). The part about booting drive A: is weird, though. Also, if you don't mount a drive or specify a path for the image filename, it must be located in …
