I found this old CD in a drawer with ten games on it, so I decided to try playing it again. I can get it to run the menu screen easily in DOSBox but I can't actually get the games to play.

<CD Drive>:\TITUS
is the command to run the game, then the menu screen has:

A Game 1
B Game 2
C Game 3
etc

I choose a letter then get the instructions screen but when I press another key it goes back to the main menu. The instructions in the CD case are in German but are the same as the game instructions on the actual CD anyway.

What is that TITUS thing? A BAT-file? If so, what does it contain?

Old Titus games were famous for having an assembler coded disk protection. I hope they have it removed. What games are these?

Intel i7 5960X
Gigabye GA-X99-Gaming 5
8 GB DDR4 (2100)
8 GB GeForce GTX 1070 G1 Gaming (Gigabyte)

Yes, TITUS is a .BAT file. I'm not sure what you mean by "What does it contain". I'm new to DOS after not using it since around 1994 but I'm fairly competent with XP.

The ten games on the CD are:
Titus The Fox
Prehistorik
Prehistorik 2
Crazy Cars 3
Blues Brothers
Blues Brothers Jukebox Adventure
Fire & Forget 2
Super Cauldron
Titan
Battlestorm

I'll get some screenshots soon if you want.

Right-click -> "Edit Titus.bat"

Hmmm... If I should venture a guess, the problems are with the programs EMPTYKB and KEY.

EMPTYKB probably empties the keyboard input buffer, and KEY waits for a new key to be pressed. Maybe those programs are doing something to the keyboard buffer that DOSBox do not support.

Since the TITUS.BAT file is on the CD, it will be hard to change it 😀 Can you copy the whole CD to some folder on your harddisk, and mount the the folder as your D-drive in DOSBox? If so, you could try removing the first 'ECHO OFF' in the TITUS-file, remove all the CLS commands, start TITUS, and see if you can spot any error messages.

PS: Instead of removing the ECHO OFF and CLS commands, you can just insert a REM in front of them:

REM ECHO OFF
REM CLS

Doing that, after pressing return having chosen a game from the list I get:

D:\>If errorlevel=28 GOTO E_TT
D:\>If errorlevel=27 GOTO END
D:\>CD TTF (I chose "A" which is Titus The Fox)
D:\TTF>..\CDRUN TTF.SQZ

Thanks for the help so far. It might be easier for me to just look around for somewhere to download the games.

It looks like it CD's into the directory and then calls the program "CDRUN" in the root of the CD to execute the file (in this case TTF.SQZ).

Going to have to load up DosBox and see if that works in DosBox.

Hey, I got it working! It turns out I just need to learn some of the features of DOSBox. I found out how to mount a virtual CD drive within DOSBox using the mount d d:\ "-t cdrom" command. 😊

I started a game and it came up with a message saying "Yeeeah! You're still playing *something (couldnt really make it out)* in 2007!"

Sorry for being a nuissance. 😅

Yes, that looks correct. The ASCII code for A is 65, and you get to that part of the TITUS.BAT from the check above that goes:

IF ERRORLEVEL=65 GOTO E_TTF

So the keyboard routines seems to work fine despite my initial guess that they were the culprits.

Nah - that would not be as fun as figuring out how to make this work 😀

Next step - what is this CDRUN thing? Another BAT-file?
