Hi.
MSX-TRA is a disassembler/debugger, with it's own working memory. You can
call it from basic with CALL MSXTRA or during boot time by holding CTRL +
STOP pressed.
MSX-TRA can prove to be very usefull when your program contains a bug which
makes the system hang completely. Just hit the reset button and hold
CTRL+STOP pressed until you are in MSXTRA. Then you can start disassembling
the program and check the memory contents. Since MSXTRA contains its own RAM,
the debugger will not overwrite any byte of your program's memory.
It has helped me in some occasions to find some rather nasty bugs.
Kind regards,
