# Mini vMac is a Macintosh II emulator. The libretro port is hardcoded for
|
|
# Mac II emulation (CurEmMd = kEmMd_II) with 68020 CPU, FPU, ADB, VIA2, ASC.
|
|
# ROM is loaded from the RetroArch system directory.
|
|
|
|
# ROM loading order (OSGLUERETRO.c LoadMacRom):
|
|
# 1. <system>/MacIIx.ROM (tried first, same 256 KB size)
|
|
# 2. <system>/MacII.ROM (defined as RomFileName in CNFGRAPI.h)
|
|
# 3. --rom command line arg (if provided)
|
|
# 4. ~/.gryphel/mnvm_rom/MacII.ROM
|
|
# 5. app parent directory
|
|
# 6. current directory
|
|
|
|
# ROM size: kROM_Size = 0x00040000 = 262144 bytes (256 KB)
|
|
# ROM checksums defined in CNFGRAPI.h:
|
|
# kRomCheckSum1 = 0x9779D2C4 (Mac II v1)
|
|
# kRomCheckSum2 = 0x97221136 (Mac II v2)
|
|
# Note: DisableRomCheck = 1, so checksum validation is skipped at runtime
|
|
# (ROMEMDEV.c patches the ROM check jump). Any 256 KB Mac II ROM works.
|
|
|
|
files:
|
|
# -- MacII.ROM (primary, required) --
|
|
# Standard Macintosh II ROM image. This is the hardcoded RomFileName.
|
|
# The core reads exactly kROM_Size (262144) bytes from this file.

Macintosh II ROM image (256 KB). The core loads this from the system
|
|
directory. Must be exactly 262144 bytes. ROM checksum verification is
|
|
disabled in the libretro build, so either Mac II ROM revision works.
|
|
|
|
# -- MacIIx.ROM (alternative, optional) --
|
|
# Tried before MacII.ROM in the loading sequence. The Mac IIx ROM is the
|
|
# same 256 KB size and is compatible with the Mac II emulation mode.

note: >
|

Macintosh IIx ROM image (256 KB). Checked first in the ROM loading
|
|
sequence. If present, it takes priority over MacII.ROM. The Mac IIx
|
|
uses the same 68020-class architecture as the Mac II.
|

|
|
notes:
|
|
emulation_target: >
|
|
The libretro build is configured exclusively for Macintosh II emulation
|
|
(kEmMd_II). Build options: 68020 CPU, FPU enabled, ADB keyboard/mouse,
|
|
VIA2, ASC sound chip. Screen: 640x480, 8-bit color depth.
|
|
disk_formats: >
|
|
Supported disk image formats: .dsk, .img, .zip, .hvf, .cmd
|
|
The core auto-inserts the loaded content as a floppy disk.
|
|
Supports up to NumDrives simultaneous disk images.
|
|
rom_checksum_note: >
|
|
DisableRomCheck is set to 1 in ROMEMDEV.c, meaning the core patches out
|
|
the ROM checksum verification at boot. This allows any valid Mac II era
|
|
ROM to work regardless of exact revision.
