This full sux from MMD is not needed here. It's just kidding
not good for any mistakes. this is not an interception method
reset.
2AlexandrKnyzev: in bank 8 at #E2DB in version 2.95
lies the program:
LD A,E
AND #10
........
He clicks pages and does incomprehensible actions and
often called from the shadow market.
But when called after a reset, the stack will be #5B?? , otherwise
In this case, the stack will be in bank 8.
In other versions of the shadow site, this program is located higher (the address is larger) on
a couple of kilobytes.
In versions lower than 2.95, the reset cannot be intercepted.
You can only intercept the reset, and let the errors be shadowed
processes. If you need more details, pick the resident one
convert.
