These openMSX save states are meant to be used with a loader  that allows these save states to be run on a normal MSX2 machine with memory mapper.
More info on this project: https://github.com/mcolom/MSX_lstate

The MSX-DOS loader for the save states can be found in the file "l v1.1.zip"

Not all of these save stated work correctly. This is a Work In Progress.
