The main difference seems to be that the graphics interface uses a different bus address and uses bitmasks which are reversed as compared to the Game Boy. I'm inferring this from GBDK's source; when you replace the linker flag -msm83:gb with -msm83:ap, the platform-specific implementations are switched out, the differences between them being:
