notes: |
|
|
CrocoDS is an Amstrad CPC 6128 emulator ported to libretro. Supports
|
|
.dsk, .sna, and .kcr file formats.
|
|
|
|
All system ROMs are compiled directly into the core binary as C byte
|
|
arrays. No external BIOS files are required.
|
|
|
|
Embedded ROMs (crocods-core/):
|
|
- cpc6128.bin.c: cpc6128_bin[32768] - CPC 6128 OS (16KB) + BASIC 1.1 (16KB)
|
|
- romdisc.bin.c: romdisc_bin[16384] - AMSDOS disk controller ROM (16KB)
|
|
|
|
ROM initialization in InitMemCPC() (crocods-core/vga.c:185-200):
|
|
- ROMINF (lower ROM, 16KB): first half of cpc6128_bin (OS)
|
|
- ROMEXT[0] (upper ROM slot 0, 16KB): second half of cpc6128_bin (BASIC)
|
|
- ROMEXT[7] (upper ROM slot 7, 16KB): romdisc_bin (AMSDOS)
|
|
|
|
Called from HardResetCPC() (crocods-core/platform.c:1009-1020) using
|
|
the extern byte arrays directly. No filesystem ROM loading exists in
|
|
the libretro path.
|
|
|
|
A Multiface ROM loader exists (crocods-core/multiface.c:51-61) that
|
|
reads LocRomMulti via fopen(), but InitMultiface() is never called
|
|
from the libretro build or platform.c. Dead code in libretro context.
|
|
|
|
The core does not request retro_system_directory or declare any
|
|
firmware entries in the .info file. need_fullpath is false.
|
|
|
|
Only the CPC 6128 model is emulated (no CPC 464/664 selection).

note: |
|
|
All ROMs are embedded. InitMemCPC() copies cpc6128_bin and romdisc_bin
|
|
into ROMINF and ROMEXT arrays via memcpy. No filesystem lookup occurs.
|
|
retro_set_environment() does not request system_directory.

note: |

2 ROM sets embedded as C byte arrays:
|
|
cpc6128_bin (32KB) - CPC 6128 OS (lower 16KB) + BASIC 1.1 (upper 16KB)
|
|
romdisc_bin (16KB) - AMSDOS disk controller ROM, mapped to slot 7

|
|
note: |
|
|
CPC 6128 only: OS in ROMINF, BASIC in ROMEXT[0], AMSDOS in ROMEXT[7]
|
|
emulator_patch_ROM() applies language patches to ROMINF after loading
