Crystals Colours improvements: [Roberto Fresca]
- Decrypted the tile matrix / video RAM. - Wrote proper memory map and inputs from the scratch. - Bypassed the program data channels protection. - Decrypted the colors / color RAM. - Added button-lamps support. - Created a default NVRAM. - Promoted to working state. - Added technical and encryption notes... Snooker 10 improvements: [Roberto Fresca] - Fixed NVRAM size. - Added default NVRAM. Apple 10 improvements: [Roberto Fresca] - Fixed NVRAM size. - Added default NVRAM. Ten Balls improvements: [Roberto Fresca] - Fixed NVRAM size. - Added default NVRAM. New games added or promoted from NOT_WORKING status --------------------------------------------------- Crystals Colours (Ver 1.01) [Roberto Fresca, Any]

To properly decrypt the thing 'on the fly' as the hardware does, I applied a bitswap into TILE_GET_INFO.

This method rearrange the tile number for each tile called to be drawn.

- Color RAM: Colors are scrambled in the following way:
|

Normal | Scrambled

offset | offset
|

----------+-----------
|
||||
0x00-0x1F | 0x00-0x1F
|
||||
0x20-0x3F | 0x40-0x5F
|
||||
0x40-0x5F | 0x20-0x3F
|
||||

|
||||
0x80-0x9F | 0x80-0x9F
|
||||
0xA0-0xBF | 0xC0-0xDF
|
||||
0xC0-0xDF | 0xA0-0xBF
|
||||
0xE0-0xFF | 0xE0-0xFF
|
||||
|
||||
|
||||
The color codes are swapped in blocks of 32 bytes. 0x20<->0x40 and 0xA0<->0xC0,
|
||||
giving us the following binary representation:
|
||||
|
||||
Normal | Scrambled
|
||||
offset | offset
|
||||
---------------+-----------
|
||||
00: 0000 0000 : 0000 0000
|
||||
20: 0010 0000 : 0100 0000 <-- changed
|
||||
40: 0100 0000 : 0010 0000 <-- changed
|
||||
60: 0110 0000 : 0110 0000
|
||||
80: 1000 0000 : 1000 0000
|
||||
A0: 1010 0000 : 1100 0000 <-- changed
|
||||
C0: 1100 0000 : 1010 0000 <-- changed
|
||||
E0: 1110 0000 : 1110 0000
|
||||
|
||||
|
||||
So, the algorithm to properly decrypt the color codes is the following one:
|
||||
|
||||
color_index = BITSWAP8(color_index,7,5,6,4,3,2,1,0)
|
||||
| |
|
||||
swapped
|
||||
|
||||
Happy end here :)
