This is a port of Paul C. Pratt's Mini vMac to the Nintendo 3DS and New Nintendo 3DS.

It is a miniature early Macintosh emulator, currently supports Macintosh Plus and Macintosh II with multiple resolution options.

Installation

Note: Requires the BIOS ROM (vMac.ROM for Macintosh Plus, MacII.ROM for Macintosh II) and disk images to run.

Disk images must be auto loaded at runtime so make sure they're named diskX.dsk where X is 1 to how many images you want to load.

Make sure to have your OS image already to go before copying your disks to your 3DS, as you cannot swap disks to complete the install on the 3DS.

Place everything (3DSX, ROM, OS image and disk images) in sdmc:/3ds/vmac/, then run with the Homebrew Launcher (for Citra, put the ROM on root).

User guide

If you are getting a flashing disk and nothing else, make sure your first disk image (disk1.dsk) is a valid bootable Mac System disk.

It's best to verify your disk images in the desktop version of Mini vMac before copying your disk images over to your 3DS.

If you're getting a black screen with the Macintosh II builds be patient, it just takes a bit to load (especially O3DS).

Supported options include:

• 1 Bit colour depth, 2 Bit colour depth, 4 Bit colour depth and 8 Bit colour depth.
• Resolutions >= 512x384 Resolutions <= 1024x1024.
• Sound Sound sample size.
• And many more, feel free to experiment.
