Well...if you can now run for example Chuckrock with 2MB from your command line, it means that your setup is OK.
Now back on your real Amiga, Churckrock should run with 1MB (like you did on the video).
The Emulation world is different from the Real one
Tomorrow, release of the 1.6 ??? (it's not for you AmBr)
I need to fix some small bugs.
