Monster World IV is a sequel to Wonderboy in Monster World (MW3), but I think it never got released outside Japan. I was just testing some things with it, but ran into trouble immediately. After loading a savestate, the title screen background got messed up:

This graphical error did not reappear in playback and the movie played correctly. I guess Gens just loaded some corrupted savestate data there?
I've completed the game once. It's quite linear, but the hardest part would be to choose what to buy and when. I'm quite sure that no armor or shield of any kind is needed, but buying a better sword at some point might speed up the boss figths significantly. Any ideas from those who have played the game?
It would be great to have some kind of rough playthrough video, just to get an idea of the project. At the moment I feel it's too long game for me.
By the way, pressing left+right makes the girl walk backwards.

Edit-2:
First boss defeated in 6 minutes. This makes me think that under 1 hour completion is unlikely. However, I managed to use enemies as platforms to reach higher places saving at least 30 seconds, so who knows what kind of shortcuts are possible eventually. To this point, the game has been very linear, but I have no idea what would be the best thing to do next. I can't continue recording until the route is made clear.
Hopefully someone has time to check this movie for possible mistakes. I think it looks great. :)
