Sega 8-bit cart emulation
|

(through slot devices)
|
||||
|
||||
Master System (Mark III) and Game Gear memory map can access 3 x 16K banks of ROM in
|
||||
0x0000-0xbfff memory range. These banks can however point to different ROM or RAM area
|
||||
of the cart (or to BIOS banks, but these are handled directly in SMS emulation).
|
||||
|
||||
Hence, carts can interface with the main system through the following handlers
|
||||
* read_cart : to read from ROM/RAM in memory range [0000-bfff]
|
||||
* write_cart : to write to ROM/RAM in memory range [0000-bfff]
|
||||
* write_mapper : to write to range [fffc-ffff] (called by the handler accessing those
|
||||
same addresses in sms.c)
|
||||
|
||||
|
||||
TODO:
|
||||
- investigate SG-1000 carts so to reduce duplicated code and to add full .sg support to sg1000m3
|
||||
- add support for sms card slot (using the same code, since the access are basically the same as
|
||||
the cart ones)
