Monkey island MCGA not working

[bit-hack]

Hi @jamieiles wonderfull project you have here!

I have an Altera-DE0-CV board here and i've been trying to get monkey island 1 running on it.
CGA mode works okay monkey c k i, however its very limited in colour palette.
When I enable MCGA mode monkey m k i, the game appears to stall at startup.

I am using the .sof file provided on your website (checksum: 02580D43) as well as your provided freedos disk image. Do I need to recompile from the latest source?

Are there any steps I am missing to get MCGA working?

Thanks!
