FreeIntv is a Mattel Intellivision emulator for libretro.
|
||||
Written for libretro by David Richardson. Intellivoice SP0256 emulation
|
||||
contributed by Joe Zbiciak (jzIntv), mask ROM embedded in source
|
||||
(src/ivoice.c:337-510, 4097-byte static array). No external ivoice ROM.
|
||||
|
||||
BIOS loading happens in retro_init() (src/libretro.c:1166-1174). The core
|
||||
calls retro_get_system_directory() then joins exec.bin and grom.bin paths
|
||||
directly. No subdirectory, no core option to disable BIOS loading.

|
||||
|
||||
loadExec() in src/intv.c:47-71 reads exec.bin as big-endian 16-bit words
|
||||
into memory range 0x1000-0x1FFF (Executive ROM, 8 KB file).
|
||||
loadExec() reads exec.bin as big-endian 16-bit words into 0x1000-0x1FFF.
|
||||
loadGrom() reads grom.bin as raw bytes into 0x3000-0x37FF.
|
||||
|
||||
loadGrom() in src/intv.c:73-98 reads grom.bin as raw bytes into memory
|
||||
range 0x3000-0x37FF (Graphics ROM, 2 KB file).
|
||||
Both files required for operation. Without them, the OSD shows
|
||||
"PUT GROM/EXEC IN SYSTEM DIRECTORY" and games do not run.
|
||||
|
||||
Both files are required. Without them the core prints an error and shows
|
||||
"PUT GROM/EXEC IN SYSTEM DIRECTORY" on the OSD, but does not abort.
|
||||
Games will not run correctly without both BIOS files.
|
||||
No hash or size validation on either file.
|
||||
|
||||
The .info file declares firmware_count = 2 with both marked opt = false.
|

|

No ECS (Entertainment Computer System) BIOS support exists in this core.
|
||||
There is no ecs.bin loading code anywhere in the source.

Memory[] is a 64K array of unsigned int (src/memory.c:26).
|

EXEC region (0x1000-0x1FFF) is write-protected in writeMem()
|
||||
(src/memory.c:60-61). GROM region (0x3000-0x37FF) is also
|

write-protected (src/memory.c:62).

|
||||
notes: |
|
||||
Raw ROMs use a fingerprint database (sum of first 256 bytes)
|
||||
to select one of 10 memory map configurations (load0-load9).
|
||||
Intellicart format is auto-detected by 0xA8 magic byte.
