Anyone did it in real hardware?
use a HLine int, when in the line 204 switch to 192 lines mode, on VBLANK int switch back to 212 lines mode, this in way to remove the bottom border.
1) Which bitmap height as maximun is possible to see in the real msx with real monitor?.
2) Does it affects the creation of the upper border timming, or the VBLANK timming?.
3) Sprites works on the bottom ?, thinks about extra space for a score / items board.
4) It is possible in screen 2 /4? how many characters rows is possible?, it will works on 3rd pattern set or will roll up to use the 1st pattern set on all the extra lines?, or the VDP will try "to access to a hipotetical 4th pattern set"?
5) the VDP will heat a bit more, by all the extra work, it overheats dangerous or it is safe?.
PD: I don't have working real hardware, so I wrote theses ideas as homework to somebody.
