need help running Astro Marine corps

did you press CTRL on booting? (to release more BASIC ram)

thanks for all the help, neither solutions were useful unfortunately.

My last resort helped though, selecting a pure MSX 1 computer to emulate seems to have solved it. After setting the vdp to 60hz everyone was as cool as i rememberd

I will try to upload a video on youtube if I can get the render option to work in bluemsx

The music seems too slow at 50 hz. I dont remember whether I played this game on my european msx 1 or japanese msx2+. It was ages ago, I dont even remember if it was a disk or tape version that I bought

50hz is too slow, the game plays much better at 60. In spectrum it was a little faster then in msx, so playing in 60 it's gets more close to the original gameplay.

And I remember in some final stage, end of part 1, I think.
It's when your mates are running away to the other direction you're going, and that some of them suddenly change into an alien which will bite your head off, but you never know until you got only 1, 2 seconds to react.
It's totally nightmare-ish, paranoid and really A*W*E*S*O*M*E.
Truly a great game IMO. It genuinely kept you scared and on your toes, meanwhile forcing you to remember enemy patterns/locations.
I think the Dinamic people were pioneers, nothing less.
