/*
|
||||
Extrema Ukrainian video fruit machines
|
||||
|
||||
The games appear to be Z80 based. ROMs are scrambled.
|
||||
|
||||
Maski Show has what appears to be a HDD image in 'WHX' (WinHex Backup) format
|
||||
Other games don't seem to have such images, missing.
|
||||
|
||||
Roms are strange sizes, they appear to be cut at the end of the last block of data, some sets contain
|
||||
roms padded to normal sizes.
|
||||
ROMs are strange sizes, they appear to be cut at the end of the last block of data. Some sets contain
|
||||
ROMs padded to normal sizes.
|
||||
|
||||
TODO:
|
||||
driver level: everything, just a skeleton for now;
|
||||
maski: convert image to CHD;
|
||||
blpearl, grancan, exsafar, maski: need decryption and splitting of the alternate versions;
|
||||
adults, bloto, extrmth, extrmti, luckshel, strlink and clones: verify if decryption is complete.
|
||||
|
||||
Some notes on the encryption:
|
||||
Every game needs a base XOR. Depending on single address bits other XORs are applied.
|
||||
In all decrypted games the sum of the address bits dependent XORs is always 0xff.
|
||||
It doesn't appear the encryption utilizes data or address line bitswaps.
