Install this emulator's files

The installer finds your setup and its BIOS folder, then downloads only the files this emulator reads there and checks each one.

Open the Start menu. Type PowerShell and open it. Paste the line. Press Enter.

PowerShell
&([scriptblock]::Create((irm https://abdess.github.io/retrobios/i.ps1))) --emulator minivmac

3 files: 1 required, 2 optional.

In this collection: 3 in repo and 0 missing.

MacII.ROM required in repo

  • Macintosh II ROM image (256 KB). Hardcoded as RomFileName. The core reads exactly kROM_Size (262144) bytes via filestream_read.
Validation and source

MacIIx.ROM optional in repo

  • Macintosh IIx ROM image (256 KB). Tried first in the loading sequence. If present, takes priority over MacII.ROM.
Validation and source

MinivMacBootv2.dsk optional in repo

  • Path: macintosh/MinivMacBootv2.dsk
  • System boot disk. Content given as a .cmd file is read as a command line, and every argument that is not an option is inserted as a disk, opened read-write first. Recalbox 10.1.1 writes a .cmd naming bios/macintosh/MinivMacBootv2.dsk ahead of the game disk. A missing image raises an open-failure message and the machine starts without it. ref: recalbox projects/configgen/configgen/recalboxFiles.py:174, recalbox projects/configgen/configgen/generators/libretro/libretroGenerator.py:877-882
