Galaksija stores ASCII codes in its 0x2800 video RAM (verified by snooping
the boot: it writes "@'READY" + ">_" prompt). The original CHRGEN ROM uses
a hardware-specific addressing that does not map char-code*8 to a glyph, so
rendering through it produced garbled output. Render the ASCII codes with
the public-domain IBM/VGA 8x8 font (font8x8 by Daniel Hepper / Marcel
Sondaar) instead -- legible green-on-black phosphor text. The boot screen
now reads "@'READY" with the ">_" input prompt, exactly like a real
Galaksija. Tests updated to check the bright-green channel.
