Use your Linux PC to play your old BBC games or develop new BBC software.. This snap is built from source found at This is an unofficial snap, not provided or supported by the upstream developer. # Guided tour Everything you need to get started is provided, and the familiar `BBC Computer 32K` message should appear straight away. ## Load a disc Go to `Drive 0` or `Drive 1` on the `File` menu to load a disc. Use the `Disc image` option to select an `SSD` file, then hit Shift+Break (PC Shift + PC F11) to start it. Changing the BBC disc image doesn't affect the file on the PC disk - after loading a disc image, there are additional `Save disc image` and `Save disc image as...` options you can use to do this manually. ## Change config The default setup is a BBC Model B with Acorn 1770 DFS and 16K sideways RAM. The `File` > `Change config` submenu lets you select something different. ## Change keyboard mapping ## The default keyboard layout maps PC keys to their BBC equivalent by position - typically what you want for games. Some games might be better with the `Default (caps/ctrl)` layout, which sets PC Left Ctrl to BBC Caps Lock, PC Left Alt to BBC Ctrl, and PC Caps Lock to BBC Ctrl. There are also two character map options, designed for typing, which try to map PC keys to BBC keys based on the character, so that PC Shift+0 gives you `)` and so on. `Default UK` is for UK-style keyboards, and `Default US` is for US-style keyboards. For US-style keyboards, press ` to get the pound sign. ## Undo/redo Use `File` > `Save state` to save your place, and `File` > `Load last state` to reload it. All state is saved, including disc contents. Use `Tools` > `Timeline...` to visualise the saved states. The timeline is shown as a tree of rounded boxes (saved states) and square boxes (open windows), with arrows showing the relationships. Click `Load` to load an old state, `Clone` to create a new window starting from that state, `Replay` to watch a replay from that state to the current state, or (*Windows/Linux only*) `Video` to save a video replay. (Video is MP4: 800Kbps H264 video + 128Kbps AAC audio.) If the timeline becomes too full of junk, click `Delete` to delete a saved state. ## Options Use `Tools` > `Options...` to bring up the options dialog, letting you fiddle with screen size and speed limiting and stuff. ### Display options Tick `Auto scale` to have the Beeb display automatically scaled based on the window size, or untick it and use the `Manual scale` filter to choose your preferred scale. `Correct aspect ratio` makes the display slightly narrower, better matching the output from a real BBC. `Filter display` lets the GPU smooth the display a bit when it's being stretched. For best results, leave these options on. For (inauthentic!) 1:1 pixel output, switch them off and set a manual scale of 1.0, or 2.0, and so on.
