from Dark_AleX:

This is same version as the one for 4.01 M33 but updated to do patches in 5.00 M33, that's why version hasn't changed yet.

Remember to discard old savestates from 4.01 before using the plugin. If you attempt to load a savestate made in 4.01
your ram would be in 4.01 M33 but the flash in 5.00 M33, and soon or later it will crash or give problems.
