|
|
Provides a base class for cartridges; the bus provided to cartridges and therefore
|
|
the interface they support is extremely machine-dependent so unlike disks and tapes,
|
|
no model is imposed; this class seeks merely to be a base class for fully-descriptive
|
|
summaries of the contents of emulator files that themselves describe cartridges.
|
|
|
|
Consumers will almost certainly seek to dynamic_cast to something more appropriate,
|
|
however some cartridge container formats have no exposition beyond the ROM dump,
|
|
making the base class 100% descriptive.
