 Posté le: Lun 31 Aoû 2020, 9:19 Sujet du message: DeskWorks Promo disk IIgs (StyleWare, 1987) |
 |
|
#1038 - This is a demo disk for MultiScribe IIgs. The demo disk is protected, and MultiScribe has its features deactivated (perharps, it is a flag in the program, I have not checked)
Disk structure
That is a standard and bootable 800K disk that contains a demo of MultiScribe IIgs.
Protection type
The usual HLS long track on side 1 of the disk. Again, and again, and again...
We learn a couple of things from the error message:
| Code: |
DeskWorks Promotional disk not found.
(Retail DeskWorks is unprotected.)
Error: EEEE
|
...with the sliding apple
1. The error is displayed very early in the boot process.
=> So, the protection check is probably in a system setup file
2. The error is displayed with the usual SysFailMgr
=> It is easy to locate the tool call in a code
Therefore, the protection will be easy to defeat!
How to copy
Use Photonix II or ZZ Copy to copy your disk then store it in a dry and safe place.
How to crack
Launch Block.Warden
| Code: |
Prefix /DeskWorks.Promo/System/System.Setup
Follow file MENUCLOCK
At offset $45: 22 -> AF
|
The disk image is available at http://www.brutaldeluxe.fr/crack/
Reboot and... enjoy,
LoGo
