Frodo was developed to reproduce the graphics of games and demos better than the existing C64 emulators. Therefore Frodo has relatively high system requirements: It should only be run on systems with at least a PowerPC/Pentium/68060. But on the other hand, Frodo can display raster effects correctly that only result in a flickering mess with other emulators.
Frodo comes in three flavours: The "normal" Frodo with a line-based emulation, the improved line-based emulation "Frodo PC", and the single-cycle emulation Frodo SC that is slower but far more compatible.
In addition to a precise 6510/VIC emulation, Frodo features a processor-level 1541 emulation that is even able to handle about 95% of all fast loaders. There is also a faster 1541 emulation for four drives in .d64/x64 disk images, .t64/LYNX archives, or directories of the host system.
Frodo runs on these systems:
