Running GLUF I noticed MEKA shows it running in 'mode 5'.
Of course it's not - it's simply the normal mode 4 with bit 1 set in VDP register 0.
I think this part of the code doesn't make much sense. There are no mode 5 (and 9) on the SMS:

so 5 should just be 4, as for the other I have no idea what's for, I suspect it could be removed.
