17) Now that we have finished removing all the dongle-check
routines, we need to re-save the file to your backup disk.
Type: < S"@0:B",08,9280,BF54 >.
18) Now that you have removed all the dongle-check routines, you
have a dongle-less working copy of Leaderboard Tournament Disk
#1. It may be backed-up with any data copier. Note: the
parameter for LB Tourn #1 on the Utility Disk represents a
variation of this break and can be run on a backup and examined
with the monitor. You'll find all changes in about the same
memory locations.
TENTH FRAME : ACCESS
Procedure:
Use the C-64 Fast Copier to make an exact data-copy of the
original. This backup will run like the original ONLY if the
dongle is in place. The following procedure will eliminate all
dongle-checks.
Working with your backup:
1) Turn on your computer and from the Utility Disk, load the Disk
Logger by typing < LOAD "DISK LOGGER",8 >. Then type < RUN >.
Insert your backup copy of Tenth Frame in the drive and log it.
The two files on the disk that contain code that check for the
dongle are called "L" and "S". Take note of the addresses in
memory where these programs reside:
"L" $081D - $3FFE
"S" $6E00 - $9FFE
This information is important since we need to load a
machine-language monitor into memory where these programs
aren't! We can choose from one of three monitors ($2000 = 8192,
$8000 = 32768, or $C000 = 49152). The monitor at $C000 does not
conflict with Tenth Frame memory, so we will use it.
2) Turn on the computer again and load the $8000 monitor from your
utility disk < LOAD "49152",8,1 > followed by < SYS 49152 > to
execute it.
3) To start with a clean slate, let's clear out all memory below
the monitor by typing < F 0800 BFFF EA >.
4) From the monitor, we must load the two Tenth Frame files. Insert
your backup copy in the drive and load both files: < L "H",08 >
