By some fluke I was able to start reading disk images by serving up bytes to the emulated 6522 using these timings." I discovered the timings a total byte would take to read of the disk for each of the four density regions. For the drive logic there is even less information. There are the original data sheets but they can be vague and confusing in areas. White – a resident of Melbourne, Australia, and Technical Director of Torus Games – told El Reg he started out on a Vic 20 in 1983 before moving to a Commodore 64 in 1984 and finally acquiring a 1541 drive in 1987.Īfter a bad experience with the SD2IEC he set about creating Pi1541 about two years ago, using his experience in 6502 assembler to emulate to process. I don’t know how many hundred-thousand drives were out there."

In Bagnall's book, Robert Russell remembered the boomerang drives heading back to Commodore: "We had 30 semi-trailers full of 1541 disk drives in the back parking lot sinking into the asphalt. The drive heads soon became misaligned, with Tom Halfhill, editor of Compute!’s Gazette, complaining that four of the magazine's seven drives failed. The Pi1541 will, however, not be emulating the horrifying failure rate of the original device.
Third-party companies later overcame some of the performance problems, and the solutions should behave correctly when introduced to the Pi1541 thanks to the thorough hardware emulation. As Russell told Bagnall: "I wasted millions of people's hours I was later told." VirtualC64 is a very promising C64 emulator, and it’s GPL too! I’ll certainly be keeping an interested eye on it, and I wish Dirk and the other project members the best of luck with it.Taking over two minutes to load a 64 kilobyte into memory was maddening.

I wonder if the emulator does strange things to the Mac while emulating mixed video modes? I mixed character and video modes in the screens I tried to capture, ah well.) Unplugging the joystick and restarting the emulator fixed that problem.Įven my Bits ‘n’ Bobs demo worked in it! (Bah, all my screenshots failed. Then the keyboard sort of worked but the left arrow character appeared for most key presses. First the keyboard wouldn’t work, and flashing a file didn’t run it automatically. If you have a usb joystick plugged in and activated in port 2 it does strange things. Fire this baby up in fullscreen mode and you’ve got your very own C64 laptop! Cool or what eh?Īs luck would have it VirtualC64 has blown a fuse just as I finish this post.

The current version of Vice uses some dodgy resolution changing in Linux (that I rarely got to work properly without screwing up my desktop) and I couldn’t get to work in Mac OS X at all. One thing it has going for it over Vice, is a real fullscreen mode.
