Additionally to that, the data for the front text layer, which was previously stored in a separate ROM, is stored at the end of the tile data. The encryption is one of the nastiest implementation of a XOR scheme ever seen, involving 9 seemingly uncorrelated 256-byte tables. All known games use the same tables except KOF2000 and MS4 which use a different set. The 32 data bits of every longword are decrypted in a single step (one byte at a time), but the values to use for the xor are determined in a convoluted way. It's actually so convoluted that it's too difficult to describe - please refer to the source below. Suffice to say that bytes are handled in couples (0&3 and 1&2), and the two xor values are taken from three tables, the indexes inside the tables depending on bits 0-7 and 8-15 of the address, in one case further xored through the table used in step 5) below. Additionally, the bytes in a couple can be swapped, depending either on bit 8 of the address, or on bit 16 xored with the table used in step 4) below. The 24 address bits are encrypted in five steps. Each step xors 8 bits with a value taken from a different table; the index inside the table depends on 8 other bits. 0) xor bits 0-7 with a fixed value that changes from game to game 1) xor bits 8-15 depending on bits 16-23 2) xor bits 8-15 depending on bits 0-7 3) xor bits 16-23 depending on bits 0-7 4) xor bits 16-23 depending on bits 8-15 5) xor bits 0-7 depending on bits 8-15 Each step acts on the current value, so e.g. step 4) uses bits 8-15 as modified by step 2). [Note: the table used in step 1) is currently incomplete due to lack of data to analyze] There are two major weaknesses in this encryption algorithm, that exposed it to a known plaintext attack. The first weakness is that the data xor depends on the address inside the encrypted ROM instead that on the decrypted address; together with the high concentration of 0x00 and 0xFF in the decrypted data (more than 60% of the total), this exposed easily recognizable patterns in the encrypted data, which could be exploited with some simple statistical checks. The deviousness of the xor scheme was the major difficulty. The second weakness is that the address scrambling works on 32-bit words. Since there are a large number of 32-bit values that appear only once in the whole encrypted ROM space, this means that once the xor layer was broken, a large table of encrypted-decrypted address correspondencies could be built and analyzed, quickly leading to the algorithm. ***************************************************************************/ static const UINT8 kof99_type0_t03[256] = { 0xfb, 0x86, 0x9d, 0xf1, 0xbf, 0x80, 0xd5, 0x43, 0xab, 0xb3, 0x9f, 0x6a, 0x33, 0xd9, 0xdb, 0xb6, 0x66, 0x08, 0x69, 0x88, 0xcc, 0xb7, 0xde, 0x49, 0x97, 0x64, 0x1f, 0xa6, 0xc0, 0x2f, 0x52, 0x42, 0x44, 0x5a, 0xf2, 0x28, 0x98, 0x87, 0x96, 0x8a, 0x83, 0x0b, 0x03, 0x61, 0x71, 0x99, 0x6b, 0xb5, 0x1a, 0x8e, 0xfe, 0x04, 0xe1, 0xf7, 0x7d, 0xdd, 0xed, 0xca, 0x37, 0xfc, 0xef, 0x39, 0x72, 0xda, 0xb8, 0xbe, 0xee, 0x7f, 0xe5, 0x31, 0x78, 0xf3, 0x91, 0x9a, 0xd2, 0x11, 0x19, 0xb9, 0x09, 0x4c, 0xfd, 0x6d, 0x2a, 0x4d, 0x65, 0xa1, 0x89, 0xc7, 0x75, 0x50, 0x21, 0xfa, 0x16, 0x00, 0xe9, 0x12, 0x74, 0x2b, 0x1e, 0x4f, 0x14, 0x01, 0x70, 0x3a, 0x4e, 0x3f, 0xf5, 0xf4, 0x1d, 0x3d, 0x15, 0x27, 0xa7, 0xff, 0x45, 0xe0, 0x6e, 0xf9, 0x54, 0xc8, 0x48, 0xad, 0xa5, 0x0a, 0xf6, 0x2d, 0x2c, 0xe2, 0x68, 0x67, 0xd6, 0x85, 0xb4, 0xc3, 0x34, 0xbc, 0x62, 0xd3, 0x5f, 0x84, 0x06, 0x5b, 0x0d, 0x95, 0xea, 0x5e, 0x9e, 0xd4, 0xeb, 0x90, 0x7a, 0x05, 0x81, 0x57, 0xe8, 0x60, 0x2e, 0x20, 0x25, 0x7c, 0x46, 0x0c, 0x93, 0xcb, 0xbd, 0x17, 0x7e, 0xec, 0x79, 0xb2, 0xc2, 0x22, 0x41, 0xb1, 0x10, 0xac, 0xa8, 0xbb, 0x9b, 0x82, 0x4b, 0x9c, 0x8b, 0x07, 0x47, 0x35, 0x24, 0x56, 0x8d, 0xaf, 0xe6, 0x26, 0x40, 0x38, 0xc4, 0x5d, 0x1b, 0xc5, 0xd1, 0x0f, 0x6c, 0x7b, 0xb0, 0xe3, 0xa3, 0x23, 0x6f, 0x58, 0xc1, 0xba, 0xcf, 0xd7, 0xa2, 0xe7, 0xd0, 0x63, 0x5c, 0xf8, 0x73, 0xa0, 0x13, 0xdc, 0x29, 0xcd, 0xc9, 0x76, 0xae, 0x8f, 0xe4, 0x59, 0x30, 0xaa, 0x94, 0x1c, 0x3c, 0x0e, 0x55, 0x92, 0x77, 0x32, 0xc6, 0xce, 0x18, 0x36, 0xdf, 0xa9, 0x8c, 0xd8, 0xa4, 0xf0, 0x3b, 0x51, 0x4a, 0x02, 0x3e, 0x53, };
