JNEXT User Guide¶
JNEXT is a ZX Spectrum Next emulator built from the official FPGA core sources. This guide shows you how to use it.
Chapters 1 to 5 are for running programs, and assume no development background. Chapters 6 and 7 are for developers: the debugger, and automating JNEXT the way its own test suite does. Chapters 8 and 9 are for everyone — what to do when something is wrong, and where everything else lives.
The complete list of command-line options is in the manual page — man jnext,
or USAGE.md. This guide links there rather than repeating
it.
