Some info.
Size =
0 = 1BDh
1 = 3BDh
Tilemap screen1 base = 800h
Tilemap screen2 base = 1000h
Tileset base = 2000h
Sprite base = 1800h
0000:7000 store the screen orientation
0000:7001 and onward can be used by the boot splash for variables
Splash flags, bit 7 > 0 = 1BPP tiles, 1 = 2BPP tiles
bit 4-0 store amount of palettes to copy.
For 1bpp tiles, each palettes store 2 colours.
For 2bpp tiles, each palettes store 4 colours.
Splash data is copied at
0600:0000
Avail color for console name:
0600:06e6 [0] 0h, F00h, F70h, FF0h
0600:06ee [4] 7F0h, F0h, F7h, FFh
0600:06f6 [8] 7Fh, Fh, 70Fh, F0Fh
0600:06fe [12] F07h, FFFh, 777h
On the VBlank code,
CS = 0600h
DS = 0600h
ES = ??
SS = 0000h
struct bootsplash_t

uint8_t padding[3];

};
Sounds seems to be
uint32_t
duration (8 bit) (in vblank)
Volume (8bit)
Pitch (16bit)
if pitch bit 7 is set then the channel is stopped.
