[hatari-devel] Fwd: Falcon memory

[Laurent Sallafranque]

It's really no effort, I can do it in 2 minutes.

This only goes against this parameter you sent me :

$FFFF8006 [R/W] B         76543210  Monitor-Type Hi
                           ||||||+-- Video Bus Breite
                           ||||||    0 = 16 Bit
                           ||||||    1 = 32 Bit (default)


If I fix 0 instead of 1 (seems to mean video bus Breite 16 bits), I can 
get the 512Ko, 2Meg or 8 Meg.
But is it logical to set this bit in a read only register that only 
seems to be fixed to 1 in the real hardware ?
(That's why I ask before doing the change).

Does Breite means size ?
