Tried all that. Still the same shitty voice 🙁

type this in game folder in windows' cmd (not in dosbox)
dir /oge /s > c:\list.txt
and post the resutling file

>>type this in game folder in windows' cmd

I'm not familiar with that procedure. Is this the same as Start/Run command?

start run cmd

Volume in drive C has no label.

It appears that version 1.1 of the game was changed so that the OPL chip is used as a DAC for digitized sound, even when an SB is detected. I'm guessing this was done as a crude "fix" to a couple of problems with SoundBlasters mentioned in the game's readme file. While DOSBox does support using the OPL as a DAC, it doesn't work all that well, and the difference is easily heard.

The version 1.1 game code still supports the SB DAC, and can be made to use it by altering the selected device number in the game's configuration file. This can be accomplished by changing the byte at offset 17h in YEAGER.CFG to 07h. If using a hex editor is a bother, the attached program will perform the modification; run it inside DOSBox in the game folder.

You guys are extremely dedicated. At first I thought most of the experts would ignore this game due to its age and unpopularity. Many thanks!! 😀

Works fine now (on cycles=auto).

Don't try this patch along with cycles=max, it will hang at the main menu! 😎

Hey, ripsaw8080

Soundblaster patch works like a charm and Chuck and I are back in the air. Now if I could only find a cheap hand-held joystick like I once had.
The keyboard works but the joystick is second nature.

Hi all,

I don't mean to necro the thread, but the info is relevant. Instead of hex editing the cfg you could have simply used blaster covox1 as your soundcard settings. They work together just fine. I discovered this when troubleshooting the same issue. I played version 1.0 then found a copy of 1.1 and the digital sound went bad so I tried the different sound settings and found a combo that gave the good music and voices. There is a special edition gravis ultrasound version that sounds even better--many more different voice samples-- although chuck's voice sounds different. Its probably the best version out there besides possibly the mac version.

Thank you! This solution is much better as it does work on higher cycles settings. And just to clear some things up. To make it work you have to start the game using the original yeager.exe. The cracked yeager.com will not work, so get your manual ready for those aircraft specification questions.

To run it you have to type "yeager blaster covox1", there are many more switches all described here

: STARTUP PARAMETERS :

When you start Yeager Air Combat, the program automatically detects the best
graphics mode for your computer and starts the game in that mode. However, if
you want to start the game in a different graphics mode, you can do so by
adding a few extra characters (called arguments) to the start command.

The program does not automatically detect CMS Boards or the Covox Speech Thing.
You need to instruct the game with an argument to use these cards.

EXAMPLE: Let's say you want to load the game with EGA graphics mode and music
generated with a CMS Board (you must have a CMS board installed). You'd type
YEAGER EGA CMS and press Enter.

The order of the extra arguments doesn't matter as long as there's a space
between each argument.

These are the arguments you can use:

CGA Loads game with CGA graphics.
EGA Loads game with EGA graphics.
MCGA Loads game with MCGA graphics (Same graphics as VGA, but slower.
Maintains compability with PS/2 25 and 30).
TGA Loads game with Tandy graphics.
VGA Loads game with VGA graphics.
SLOWCARD When you are in MCGA or VGA mode, if the game freezes on
startup, or if you get sound but the wrong colors or no colors at
all, try this parameter. It slows down the interface between
the computer and the video card.
FASTCARD Deactivates Slowcard.
JOYSTICK Loads game with joystick flight control.
KEYBOARD Loads game with keyboard flight control.
MOUSE Loads game with mouse flight control.
MOUSE2 Loads game with high-resolution mouse flight control.
LOW Loads game in low graphics detail mode (less detail speeds up
game play).
MEDIUM Loads game in medium graphics detail mode (less detail speeds up
game play).
HIGH Loads game in high graphics detail mode.
NOSOUND Loads game with sound turned off.
NOSPEECH Loads game with digitized speech turned off. It also reduces the
amount of disk swapping necessary when playing on four 360K
floppies.
PC Loads game with PC internal speaker sounds.

ADLIB Loads game with AdLib sound card sounds.
BLASTER Loads game with Sound Blaster sound card sounds.
TANDY Loads game with Tandy 1000 sound.
TANDYDAC Loads game in Tandy 1000 models equipped with DAC (such as
the Tandy 1000 TL),which results in clearer digitized speech.
COVOX1 Loads game with loud speech driver for the Covox Speech Thing
on parallel port 1. Note: there is no auto-detect for Covox so
this parameter is required if you want to use Covox.
COVOX2 Loads game with loud speech driver for the Covox Speech Thing
on parallel port 2. Note: there is no auto-detect for Covox, so
this parameter is required if you want to use Covox.
CMS Loads sound driver for CMS music board. Note: there is no
speech driver for CMS, so digitized speech will play through
the PC's internal speaker. Also, there is no auto-detect for
CMS, so this parameter is required if you want to use your
CMS Board.
SMALL Use this if you have a computer with less than 640K of memory.
It deletes complex versions of some shapes to speed up the
simulation.
LARGE Deactivates Small.
ALL If you want to be able to play all missions without having to
win each one, type this parameter to make all missions available
immediately. This is a default parameter.
CAMPAIGN Starts new campaign. In order to advanced in Campaign Mode,
you will need to land safely at your home base after successfully
completing each mission.

Note: when you quit the game, the program automatically remembers all of that
game's startup parameters, as well as all the items checked on the drop-down
menus. The next time you start the game, just type YEAGER and press Enter, and
those same parameters and menu items will be in effect. Also, if you quit the
game in the middle of a Campaign, and you want to retum to where you left off,
be sure not to select the Campaign parameter the next time you start up the
game, as that will put you at the beginning of a new campaign.

More Necro,

I recently tried to get Chuck Yearger's Air Combat working on my Win 10 computer and had problems.

My computer has a soundblaster card, and if I entered it in the dosbox conf file, the game would run, and sound good, but it would crash after selecting an Historic Mission. If I did not specifiy the Soundblaster, the crash was gone, but the sound was basic pc speaker.

After checking out this thread, and quite a bit of mucking about with conf settings, I found the following settings gave me great sound and fewer crashes.
I set the Dosbox config file to specify SB as the sound card, and added "VGA Blaster" arguments after Yeager in the start command.

This was still a bit flaky, it would sometimes work fine and other times still crash, what I found that got it stable was to lower the Dosbox config cycles setting to 6000 instead of max.
