Z80 Cracks

ZXNet echo conference «zx.spectrum»

From Roman Khroupnin To All 23 September 1997


High All!

So that's it, absolutely this whole thing worked for me for
"Z80TRDOS" v.2.01 (15.08.95) and
"Z80" v.3.02 (issue 03.11.94) <----- although here on the splash screen it says 3.0

In this info There are minor differences with what I got, in general the difference is in the offsets by 10 bytes. You need to edit a larger fragment and
find out this difference, maybe it will be equal to 0. In short, here it is...

Salyut, All!

... here are the cracks for Lunter's Z80 emulator (those that we managed to find):

=== Begin Z80TRDOS.DOC ===
In order to crack the Z80TRDOS.EXE program,
it must first be unpacked since it was initially
compressed by the PKLITE v1.12 program.
Any of the following is suitable for this programs:
TRON, X-TRACK, UNP, well, maybe some others
which I don’t know yet.
Initial file length: 70214
Length after unzipping: 202832
After you expand the program, place
it in the directory with programs:
CRACKER.EXE,Z80.CRK
and run the CRACKER.EXE program, then I think
you'll figure it out yourself.

The program was successfully broken by:
Yuri Kverznev and Evgeny Mazanov (2:5054/12.12)
and also thanks for the help:
Andrey Gerasimenko (2:5054/398)
