HI guys,
I have problem with memory scanner [ON-D] [BACKSPACE].
When I start to hack into the EQ-LIB card by XLIBS in the 'TOOLS'.
It says that Library 271 (COLIB :Constants Libr) start at #926DFh.
Then I used the memory scanner to look at that address.
Guess what I get....
(in mem-scanner) 926DF:D992053621FEF30B
That the problem!!!!
We know that library will begin with prolog #02B40h Right?.
Then I use PEEK (by Alonzo..) at #926DFh.
I got # 4F431501D4A02B40h which will equivalent to
926DF:04B20A4D105134F4 in mem-scanner.
That is what it should be.
I also checked that the mem-scanner begin to 'distort' at #90000h
address.
- How do you guys thin about this?
- Is it some form of copy protection or whatever?
- If YES it is copy protection or anything that they did to protect
their card. How can we believe that all the ROM which we DUMP out
to use with Voyager is correct? Because if they protect their ROM
card, why don't they protect their ROM.
BTW, my 48SX is revision E and the EQLIB card is in slot #1.
Thank in advance for clarify,
