I am surprised that this item has not shown up in the news section yet...
Indeed, this is a major news, it should receive a proper announcement in the front page of MRC. 
Great job guys!! As always 
Perfect! Lost some time
Tested. It works pretty fine until i get to about... the 2nd mountain of the first level, the one you seem you can pass thru.
The Sha1Sum of the rom does the right value.
Maybe the issue is that I'm using real MSX 
Sony F9S here.
It just freezes. The music keeps playing finely. Anything else is stuck.
Um.. again, problems.
At level 4, after dying, when you typically get the CONTINUE message, freezed again. This time even music was stuck
