The Games: winter edition (Epyx, 1987)

[toinet]

It's the next best thing to being there. These seven events, modeled after the official competition, put you right there in the Canadian Rockies competing against the fastest and strongest athletes in the world.

That game is really nice: DHGR everywhere. Nice music, neat animations... and bad protection.


PROTECTION TYPE
On a standard DOS 3.3 diskette, only the first side of the first disk is protected. The four others can be locksmithed.
- Change of end markers (D5 AA 96, FF FF EB, D5 AA AD, FF FF EB)
- Desynchro on track 0


DISK COPY
- Launch Advanced Demuffin
- Change the end markers DE AA with FF FF
- Copy the disk
If you, then, boot the disk, it fails to do so as the desynchro has not been removed yet.


REMOVE THE DESYNCHRO
- Eight values are read from the disk (FC EE EE FC E7 EE FC E7)
- They are stored from $F0 to $F7
- $F3 value is used to EOR $B700..$B7FF => FC
- $F2 value is used to EOR $B800..$B8FF => EE
- $F1 value is used to EOR $B900..$B9FF => EE
- $F0 value is used to EOR $BA00..$BAFF => FC

- Launch Disk Fixer
- Read T0/S1, press X, enter EOR FC, press CTRL-T, save T0/S1
- read T0/S4, save T0/S4
- press X, enter EOR EE, read T0/S2, save T0/S2
- read T0/S3, save T0/S3
- press CTRL-T to turn the filter off
- Read T0/S0, at offset $4A, replace 4C 00 BB with 6C FD 08
- Save T0/S0

Reboot and enjoy your working backup copy...
