demo: boot the SL0PBOY-forked BIOS in the README gifHEADmaster
gbdemo resolves a bare --bios to bios/sl0pboy_bios.bin when present (else stock gbc_bios.bin). Generate the fork with the emulator's tools/mk_sl0pboy_bios.py. The gif now opens on the SL0PBOY boot animation - logo drop, colorize, chime - before gbos comes up.
