New MESS ROM format
We are currently considering new formats for ROMS, which will allow - in the case of our TI - to pack all related ROM dumps in one file. But more important, we can add meta information, like telling the emulator to allocate RAM for module RAM, which banking scheme to use, and more.
The favored approach currently seems to be to declare the circuit board (PCB) of the module instead of the logic.
<romset> Content: (sources, deploy, soft) </romset>
<sources> Content: (rom | chd | ram)* </sources>
ROM, Comphunk, RAM:
<rom id = Name file = Name address = nonNegativeNumber : "" size = nonNegativeNumber : "" crc = Hex32 : "" sha1 = Hex160 : "" /> <chd id = Name file = Name md5 = Hex128 : "" sha1 = Hex160 : "" /> <ram id = Name base = Name : DriverName address = nonNegativeNumber : "" size = nonNegativeNumber type = ( unbuffered | nvram ) : unbuffered />
<deploy> Content: (pcb | mount)* </deploy>
<pcb id = Name type = Name> Content: (Socket | Feature)* </pcb> <socket number = nonNegativeNumber uses = Name /> <feature name = Name> Content: (any) </feature> <mount id = Name type = Name source = Name device = Name name = Name />
<software usedriver = (true | false ) : false > Content: (system*, item*) </software>
<system driver = Name bios = Name default = ( true | false ) : false /> <item set = Name : "" name = Name : "" maker = Name : "" year = nonNegativeInteger : "" > Content: (pcb?, mount*) </item> <pcb ref = Name /> <mount ref = Name />
