Mini vMac for Playdate

Port of Mini vMac to the Panic Playdate console. It's not very usable due to slowness and limited input.

Features

• Emulates a Macintosh Plus, but is around 3.5 times slower.
• Screen matching the Playdate (400×240). This is smaller than any Macintosh, which will break some software.
• Draws screen at around 4 fps.
• No sound (disabled for performance).
• Controls:
  • D-pad: mouse movement or WASD (set in menu)
  • A button: mouse button
  • B button: space bar
  • Crank: arrow up/down
• Load vMac.rom and disk images from Data/net.namedfork.minivmac
• Press the menu button to switch input modes or insert disks

Installation

• Build or download minivmac.pdx from releases.
• Copy minivmac.pdx to the Playdate's Games directory, or sideload it from the web.
• Copy vMac.rom and any disk images to the Playdate's Data/net.namedfork.minivmac directory (create it if it doesn't exist).

Building

Requires installing the Playdate SDK, and having the PLAYDATE_SDK_PATH environment variable set.

Device

• Create a build directory and initialize it

mkdir build.dev
cd build.dev
cmake -DCMAKE_TOOLCHAIN_FILE=$PLAYDATE_SDK_PATH/C_API/buildsupport/arm.cmake -DCMAKE_BUILD_TYPE=Release ..
make

• minivmac.pdx will be built in the root directory

Simulator (Xcode on macOS)

• Create a build directory and initialize it

mkdir build.sim
cd build.sim
cmake .. -G Xcode -D CMAKE_C_COMPILER=cc

• An Xcode project minivmac.xcodeproj will be generated
• You can open and run this from Xcode
