(MESS) megadriv.c: more updates [Fabio Priuli]
 - implemented correct ROM mirroring, based on research by Eke & others
 - emulated the protection in Ya Se Chuan Shuo, promoting it to work state
 - fixed cart type in Blockbuster World Video Game Championship II (works for the first time in MESS)
 - fixed cart type in HardBall III, Barver Battle Saga and Chao Ji Da Fu Weng
 - added support for unusual SRAM location in HardBall 95
 - fixed a few regressions introduced in the previous commit
 - fixed wrong driver class being used in 32x and SegaCD

19 TODO: currently read access in 0x000000-0x7fffff are not masked (so we assume that no game attempts to
20       read beyond its ROM size). A regression test is pending to identify which games need this and mirror
21       them properly (Eke's doc states ROM data should be mirrored), but none of the ~120 games I tried
22       attempted that and a testcase would be appreciated
2319 
20   Cart Mirroring (based Eke's research)
21
22   MD Cartridge area is mapped to $000000-$3fffff: when accessing ROM, 68k address lines A1 to A21 can be
23   used by the internal cartridge hardware to decode full 4MB address range.
24   Depending on ROM total size and additional decoding hardware, some address lines might be ignored,
25   resulting in ROM mirroring.
26 
27   Cartridges typically use either 8-bits (x2) or 16-bits (x1, x2) Mask ROM chips, each chip size is a
28   factor of 2 bytes.
29   When one chip ROM1 of size 2^N is present, it is generally mirrored each 2^N bytes so that read access
30   to cart area sees the sequence ROM1,ROM1,ROM1,... (up to 4MB)
31   When two chips ROM1 & ROM2 are present and the whole size is 2^N, then the block ROM1+ROM2 is mirrored
32   in the cart area, and reads see the sequence ROM1+ROM2,ROM1+ROM2,... (up to 4MB)
33   When two chips ROM1 & ROM2 are present and the whole size is not 2^N (e.g. because ROM1 and ROM2 have
34   different sizes), then the area between the end of ROM2 and next power 2^N is generally ignored, and
35   reads see the sequence ROM1,ROM2,XXXX,ROM1,ROM2,XXXX... (up to 4MB)
36 
37   At loading time we first compute first power 2^N larger than cart size (see get_padded_size function),
38   we allocate such a size for ROM and we fill of 0xff the area between end of dump and 2^N.
39   Then we handle mirroring by creating a rom_bank_map[] (see rom_map_setup function) which points each
40   access in 0x000000-0x400000 to the correct 64K ROM bank.
