Mega//e for the MEGA65 🍎

V1 of the Apple IIe core for the MEGA65.

This release adds quite a bit of functionality and makes the core much nicer to use on real MEGA65 hardware.

Highlights:

• Apple IIe / Enhanced IIe support
  
• Dual Disk II drive support
  
• Amiga mouse support
  
• Atari/Commodore-style joystick support
  
• Second joystick button via POTX/POTY, with selectable POT and polarity
  
• New MEGA65 keyboard mapping mode that follows the actual MEGA65 keycap glyphs
  
• ALT acts as a second modifier for the symbols printed on the front of the MEGA65 keycaps (~ | \ { } _ etc.)
  
• Original Apple II positional keyboard mapping remains selectable
  
• Multiple colour palettes: NTSC, IIgs, AppleWin and Apple IIc PAL
  
• PAL/NTSC analog video selection
  
• Apple IIe ROM region switching
  
• Low-Res/Text composite colour-artifacting option
  
• Retro 15Khz or 31Khz analog video supported

Disk images: .nib is currently the officially supported floppy format. .dsk images can be converted with dsk2nib; broader disk-image support is something I want to investigate. Use dsk2nib or Ciderpress to convert images.

There are still things to do; including HDD support, Commodore 1350/1351 mouse support, Atari ST mouse support is also feasible and further testing of some existing Apple II functionality.

⚠️ Do not connect an original Apple II mouse directly to the MEGA65 joystick port. Despite using a similar connector, its electrical pinout is incompatible, including the +5 V/GND arrangement.

AMIGA 500 OCS Version 2 Alpha 6

Heavily improved physical disk reading. Should work reliably now:

a) Either configure the physical disk drive as df0: and boot your old gems,

b) or configure the physical drive as df1: or df2: and use XCOPY to preserve your old disks by copying them to empty .adf files (that you prepared beforehand) on your SD card.
