!!! Loading syntax
To load a tape in 16k and 48k models, type {{J}} [[__LOAD__]], {{Symbol Shift + P}} [[__"__]] twice and {{Enter}}.
!!! Issues
* Tape images are read-only. This may change in the future, but with bizhawk's savestate system this is not strictly a necessity
* Disk images are currently read-only as well. There is certain write functionality implemented within the emulated UPD756A disk controller (in order to make games work that require this), but this is not persistent
* Disk drive emulation timing is currently not accurate, meaning that disk games will load faster than they would on a real +3. Due to how the Spectrum interfaces with the disk controller though, this should not cause any compatibility issues
