Caprice32 is an Amstrad CPC emulator ported to libretro. Supports CPC 464,
|
|
CPC 664, CPC 6128, and CPC+ (Plus) models.
|
|
|
|
All system ROMs are compiled directly into the core binary as C header
|
|
arrays in cap32/rom/*.h. No external BIOS files are required.
|
|
|
|
Embedded ROMs (cap32/cap32.c:342-345):
|
|
- cap32/rom/464.h: OS_BASIC10[32768] - CPC 464 OS + BASIC 1.0
|
|
- cap32/rom/6128.h: OS_BASIC11[32768] - CPC 6128 OS + BASIC 1.1
|
|
- cap32/rom/amsdos.h: AMSDOS[16384] - AMSDOS disk controller ROM
|
|
- cap32/rom/6128p.h: OS_6128P - CPC+ system cartridge ROM
|
|
- cap32/rom/cpm.h: cpmROM - CP/M boot snapshot (128KB)
|
|
|
|
ROM selection in emulator_select_ROM() (cap32/cap32.c:1072-1100):
|
|
- CPC 464: OS_BASIC10 (32KB)
|
|
- CPC 664: OS_BASIC10 (32KB) + AMSDOS in slot 7
|
|
- CPC 6128: OS_BASIC11 (32KB) + AMSDOS in slot 7
|
|
- CPC+: OS_6128P loaded as system cartridge via cpr_load()
|
|
|
|
The standalone (non-libretro) version references external filenames
|
|
cpc464.rom, cpc664.rom, cpc6128.rom, amsdos.rom in cap32.c:349-352
|
|
via config file loading (cap32.c:1828-1840), but the libretro port
|
|
does not use this path. The libretro init (libretro-core.c:1512) has
|
|
a "TODO: future use to load custom bios" comment that is not
|
|
implemented.
|
|
|
|
Keyboard layout patches are applied to the ROM in memory for French
|
|
and Spanish layouts via rom_mods.h (cap32.c:1102-1126).
|
|
|
|
CP/M support loads a pre-built snapshot (cpm.h) into memory via
|
|
snapshot_load_mem() in slots.c:87.

notes: |
|
|
All ROMs are embedded. emulator_select_ROM() copies the appropriate
|
|
ROM array into the pbROM buffer based on CPC.model. No filesystem
|
|
lookup occurs in the libretro port. The retro_system_bios_directory
|
|
variable is set up in libretro-core.c:1499-1510 but only used for
|
|
a future custom BIOS feature that is not yet implemented.
