Studymate v2 3.5" (Compu-Teach, 1990)

#942 - Another eduware to perform tests, yeepee!

Disk structure
This is a standard ProDOS 3.5" disk with 70k out of 800 used! Note that my original disk was bad: the ProDOS and BASIC.SYSTEM could not be copied, so I've generated a new disk with both files from v1. The program files are from the original v2 disk.

How to copy
Use ZZCopy or Photonix II to copy your disk. Then, store it in a dry and safe place.

Protection type
As with v1, the protection is a password check from the manual. Located in the UNPACKER file at $0C00, it is called by the basic program STARTUP at line 25 by the CALL 3072.

How to crack
As with v1, we have to follow the code and see where it ends (and calls the next program to be run). The address is at 3304 in decimal. So...

Launch Basic.System
Prefix /STUDYMATE
Load Startup
25 VTAB 18:PRINT "PRESS ANY KEY TO CONTINUE":CALL 3304
Save Startup

Reboot and... enjoy,
