rodo/MacOS is an extremely robust Commodore 64 Emulator for the Macintosh. Frodo was developed to reproduce the graphics of games and demos with higher precision than the existing C64 emulators. To that end, Frodo can display raster effects correctly that only result in a flickering mess with other emulators. In addition to the precise VIC emulation, Frodo features a processor-level 1541 emulation that is able to handle about 50% of all fast loaders. There is also a faster 1541 emulation for four drives containing .D64, .X64, .T64, or .LYNX files. Sound (SID) emulation is also provided. Frodo/MacOS includes a single cycle emulator, Frodo SC, that has almost 100% compatibility at the expense of speed.
