I spent all the day if I can use all screen modes on Colecovision
Modes 1 and 2 are easy.
But I can't get screen o and 3.
Mode 0:
Reg/Bit 7 6 5 4 3 2 1 0
0 - - - - - - M2 EXTVID
1 4/16K BL IE M1 M3 - SI MAG
0 0 0 0 0 0 0 0
1 0 1 0 0 0 0 0
vdp_out(0,0);
vdp_out(0,0xA0);
I disabled BL because screen 0 has no sprites anyway.
This code doesn't work
Mode 3
Reg/Bit 7 6 5 4 3 2 1 0
0 - - - - - - M2 EXTVID
1 4/16K BL IE M1 M3 - SI MAG
0 0 0 0 0 0 0 0
1 1 1 0 1 0 0 0
vdp_out(0,0);
vdp_out(0,0xE8);
This code doesn't work either
I expect the letters in mode 0 would be smaller
And mode 3, sprites would be look with big pixels.
I will stick with mode 2 since, the characters are big enough and the sprites are just fine.
