kill off old ST-V protection simulation code, all games now use the 315-5881 emulation
(except decathlete of course, because that's a completely different chip)

I think this is an encryption device. Decathlete is also protected, but uses a different device

see machine/decathlt.c for details of that one, unlike this that appears to perform decompression

operations.

Astra Superstars data were extracted from Saturn version of the game. It is not known if

protection device has data stored inside, or they are read from roms (using decryption/decompression)

=========================================================================================
|
|
||||||
y = setted as a 0,then after the ctrl data is moved is toggled to 1 then again toggled
|
|
||||||
to 0 after the reading,this bit is likely to be a "calculate protection values"
|
|
||||||
if 1,use normal ram if 0.
|
|
||||||
* = working checks
|
|
||||||
[3,low word]AFAIK this is the cartridge area and it's read-only.
|
|
||||||
(1)That area is usually (but not always) used as system registers.
|
|
||||||
(2)Same as P.O.S.T. check,it was really simple to look-up because of that.
|
|
||||||
(3)Wrong offset,or it requires something else like a bitswap?
|
|
||||||
=========================================================================================
|
|
||||||
Protection works as a sort of data transfer,it could also be that it uses
|
|
||||||
encryption on the data used...
|
|
||||||
|
|
||||||
For now I'm writing this function with a command basis so I can work better with it.
