CARTRIDGE ROM MIRRORING
|
||||||
|
***************************************************************************************************************
|
||||||
|
|
||||||
|
Cartridge area is mapped to $000000-$3fffff:
|
||||||
|
|
||||||
|
-> when accessing ROM, 68k address lines A1 to A21 are used by the internal cartridge hardware to decode the
|
||||||
|
full 4MB address range.
|
||||||
|
-> depending on the ROM total size, some address lines might be ignored, resulting in ROM mirroring.
|
||||||
|
|
||||||
|
|
||||||
|
Cartridges can use either 8-bits (x2) or 16-bits (x1, x2) Mask ROM chips, each chip size is a factor of 2 bytes:
|
||||||
|
|
||||||
|
-> two 8-bits chips are equivalent to one 16-bits chip, no specific address decoding is required, needed
|
||||||
|
address lines are simply connected to each chip, upper address lines are ignored and data lines are
|
||||||
|
connected appropriately to each chip (D0-D7 to one chip, D8-D15 to the other one).
|
||||||
|
ROM is mirrored each N bytes where N=2^(k+1) is the total ROM size (ROM1+ROM2,ROM1+ROM2,...).
|
||||||
|
|
||||||
|
-> one single 16-bits chip do not need specific address decoding, address lines are simply connected
|
||||||
|
depending on the ROM size, upper address lines being ignored.
|
||||||
|
ROM is mirrored each N bytes where N=2^k is the size of the ROM chip (ROM1,ROM1,ROM1,...).
|
||||||
|
|
||||||
|
-> two 16-bits chips of the same size are equivalent to one chip of double size, address decoding generally
|
||||||
|
is the same except that specific hardware is used (one address line is generally used for chip selection,
|
||||||
|
lower ones being used to address the chips and upper ones being ignored).
|
||||||
|
ROM is mirrored continuously each N bytes where N=2^(k+1) is the total ROM size (ROM1,ROM2,ROM1,ROM2,...).
|
||||||
|
|
||||||
|
-> two 16-bits chips with different size are mapped differently. Address decoding is done the same way as
|
||||||
|
above (one address line used for chip selection) but the ignored & required address lines differ from
|
||||||
|
one chip to another, which makes ROM mirroring different.
|
||||||
|
ROM2 size is generally half of ROM1 size and ROM are mirrored like that : ROM1,ROM2,ROM2,ROM1,ROM2,ROM2,...
|
||||||
|
|
||||||
|
From the emulator point of view, we only need to distinguish 3 cases:
|
||||||
|
|
||||||
|
1/ total ROM size is a factor of 2: ROM is mirrored each 2^k bytes.
|
||||||
|
|
||||||
|
2/ total ROM size is not a factor of 2 and cartridge uses one or two chips of the same size (Type A):
|
||||||
|
ROM is padded up to 2^k and mirrored each 2^k bytes.
|
||||||
|
|
||||||
|
3/ total ROM size is not a factor of 2 and cartridge uses two chips of different sizes (Type B):
|
||||||
|
ROM is not padded and the first 2^(k-1) bytes are mirrored each 2^k bytes while the next 2^(k-2) bytes are
|
||||||
|
mirrored in the last 2^(k-2) bytes.
