Hi-Res Soccer (On-Line Systems, 1980)

#1014 - Hi-Res Soccer by Jay Sullivan. Disk image by Stephane Racle.

Disk structure
The disk is a standard DOS 3.2 (13-sec disk). It can be read, copied. It shows no sign of on-disk protection.

Protection type
But there is one. If you copy the disk (DOS 3.2 to DOS 3.2 or to DOS 3.3), the HELLO file is run, it loads the BANNER file and BRUNS the SOCCER file that hangs. The protection checks nibbles on T0/S0.

How to copy
We'll put the file onto a standard DOS 3.3 slave diskette. Perform the following operations:
- Insert a DOS 3.3 Master disk in drive 1 and boot it
- Insert a blank disk in drive 2 and type INIT HELLO,D2
- Now, boot my copy disk,
- Launch Advanced Demuffin 1.4, press P to bypass boot,
- Load RWTS at page $B7, file is DEMU.RWTS3.2,D1
- Enter the monitor
- B963:18
- Press ctrl-Y to return to the program
- Copy 13-sec from T3/S0 to T22/SC

How to normalize
Now, boot my copy disk and launch Disk Fixer, we still have the DOS 3.3 version of Hi-Res Soccer in drive 2. Now put it in drive 1 and perform the following change:
- Press D to display the catalog, follow file SOCCER
- At sector offset $E, byte offset $3B: 20 -> 2C
- Save the sector
You're done

There are no deleted files on the disk
