#17 Logo on frame-2 isn't compatible with existing real hardware
Currently, the C-BIOS logo is placed on frame-2 (8000h~BFFFh), but no existing MSX hardware allows more than 32KB of main ROM. I know C-BIOS don't requires the logo to boot, but there's still plenty of space available at the frame-1 (4000h~7FFFh) because the BASIC isn't there anyway. So the logo can be safely placed there.
One day, when a BASIC is implemented, the logo can be moved to somewhere else.
it was in the main rom part in the past, but we've moved it outside of that 32K because of the possibility to implement BASIC safely.
