# retrovnc
|
||||
|
||||
a headless Libretro frontend that exports a VNC server.
|
||||
|
||||
# Dependencies
|
||||
|
||||
- A C++ toolchain
|
||||
- A Rust toolchain.
|
||||
- Maybe libvncserver (i'm not sure, it seems like the package can build it).
|
||||
|
||||
# Building
|
||||
|
||||
`$ cargo b --release`
|
||||
|
||||
# Usage
|
||||
|
||||
`$ retrovnc --core <CORE> --rom <ROM>`
|
||||
|
||||
For disc-based titles it is probably a good idea to pass the cuesheet file. I will implement stuff later to make this less annoying.
