Running Files:
You may run programs by simply dragging and dropping files onto the virtual screen of the emulator.
Supported file formats are:

• generic CBM prg-format (file extensions ".prg" or ".pet"),
• P00-files (file extensions ".p00" … ".p99"),
• programs on D64 / D80 / D82 disk images (".d64", ".d80", ".d82")
• T64 tape archives (".t64"),
• BASIC source files (text files with extensions ".txt", ".ba" or ".bas").
• 6502 assembler sources (text files with extensions ".a", ".as", ".asm", ".a65", ".s" or ".src") and BASIC source files with appended assembler source code.

Binary files will be run automatically (hold SHIFT to override), while BASIC source files are just loaded in order to allow for an inspection of the generated BASIC program. (BASIC source files may be both in lower and upper case, case is evaluated on a per-word basis. While common Unicode substitutes for non-alphabetic PETSCII characters should work, best use "chr$()" or the special PETSCII escapes instead.)
You may also provide a BASIC source text as URL-Data. See the link console to craft such a URL.
For best gaming experiences set the keyboard to "Games"-mode (no simulated key repeat and immediate touch interaction) from the pop-up menu at the bottom of the virtual screen.

Directories are fully emulated for disk images and tape archives (emulated as disks in drive 8), including LOAD commands and directory listings from BASIC, wildcards and type selectors. Please mind that the emulated IEEE interface currently doesn’t support advanced BASIC 4.0 disk commands. (E.g., please use the traditional “LOAD "$",8” instead of “DIRECTORY”.)

New in version 2.0:

• accurate CPU read/write timing
• cycle accurate video rendering
• enhanced phosphor emulation
• enhanced matrix printer hard-copy emulation
• enhanced support for common Unicode substitutes for PETSCII characters and the legacy computing range
• BASIC variables dump/read-out
• context aware disassembly (including 6502 code, BASIC text and variables)
• drag&drop 6502 assembler
• assembler continuation for BASIC sources
• sound
• support for joysticks/gamepads and various adapter schemes (incl. SNES serial controllers)
• keyboard joystick emulation (cursor keys and SPACE with CAPS LOCK)
• support for D80 and D82 disk images
• file extraction from archives (via an item’s context menu)
• support for locally stored save states (temporary mount points)
• various changes to the internal architecture
• we run all of the demos :-)

Many thanks to Jason Cook for beta testing and helpful discussions!

Note for iPad users (9.5in): Consider adding this page to your home screen. If started from there, the navigation bar will be hidden and the interface should just fit the screen.
Older devices on the more feeble side, like 32-bit iPads, may struggle over the use of the AnimationFrame API. These work still fine with the older version 1 of the emulator.
