Various files
xfer (v1.0.1) : Command-line tool that allow to send files and receive from a M4 Board. Possibility to add a AMSDOS header too.
M4 Board relay rom : When moving M4rom out of position 1-7 / 1-16 it will no longer be initialized, therefore this rom should be placed at rom7 or lower. This is if you want to use 32 roms of XMEM and map M4 romboard after it. You should program the XMEM or other romboard with M4 bootrom in pos 1-7, it will look for M4 rom from 1-127 and initialize it + pass commands through to it
