Frodo is a Commodore 64 core for RetroArch. This guide summarizes what the official libretro documentation states about the core: who authored it, its license, the content formats it accepts, its database association, its core option, and which emulation features it does and does not support. It is a source summary, not a record of first-hand testing.
Background and licensing
The Frodo core is credited to Frodo Team Members and is released under GPLv2. RetroArch maintains a separate summary of the licenses behind itself and its cores for readers who want the broader picture.
Content formats the core loads
The documentation lists the following extensions as loadable by the Frodo core. Commodore 64 disk and tape images such as .d64 and .t64 are included, along with several other image and archive formats.
- .d64
- .t64
- .x64
- .p00
- .lnx
- .lyx
- .zip
The core is associated with the "Commodore - 64" database in the libretro-database project, and the core's internal library name is "Frodo".
Core options
The documentation lists a single core option, Internal Resolution (frodo_resolution). Its default is 384x288, and the available values range from that default up to 1024x1024. The option is exposed inside RetroArch's core options menu while the Frodo core is loaded.
Feature support
According to the feature support table, the Frodo core supports core options but does not support save states or rewind. Players who rely on those RetroArch features should know they are documented as unavailable here rather than assume they work.
