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]

	412	- Color RAM: Colors are scrambled in the following way:
	413
	414	Normal  | Scrambled
	415	offset  |  offset
	416	----------+-----------
	417	0x00-0x1F | 0x00-0x1F
	418	0x20-0x3F | 0x40-0x5F
	419	0x40-0x5F | 0x20-0x3F
	420	0x60-0x7F | 0x60-0x7F
	421	----------+-----------
	422	0x80-0x9F | 0x80-0x9F
	423	0xA0-0xBF | 0xC0-0xDF
	424	0xC0-0xDF | 0xA0-0xBF
	425	0xE0-0xFF | 0xE0-0xFF
	426
	427
	428	The color codes are swapped in blocks of 32 bytes. 0x20<->0x40 and 0xA0<->0xC0,
	429	giving us the following binary representation:
	430
	431	Normal     | Scrambled
	432	offset     | offset
	433	---------------+-----------
	434	00: 0000 0000 : 0000 0000
	435	20: 0010 0000 : 0100 0000 <-- changed
	436	40: 0100 0000 : 0010 0000 <-- changed
	437	60: 0110 0000 : 0110 0000
	438	80: 1000 0000 : 1000 0000
	439	A0: 1010 0000 : 1100 0000 <-- changed
	440	C0: 1100 0000 : 1010 0000 <-- changed
	441	E0: 1110 0000 : 1110 0000
	442
	443
	444	So, the algorithm to properly decrypt the color codes is the following one:
	445
	446	color_index = BITSWAP8(color_index,7,5,6,4,3,2,1,0)
	447	| |
	448	swapped
	449
	450	Happy end here :)
