Anyone who has some information about reading/writing the on-cart real-time clock? I know some information can be obtained from the VBA source, but I'm more into some documentation on this rather than implemented source..

it worked on my boktai cartridge, but visual boy advance didn't like the code.

Are you refering to my RTC Demo code?
It is a multiboot image. Make sure VBA loads it as such.

Hey, umm... do you think if I gave you a copy of the EZFA loader you could figure out how to use the RTC.

Flash cards with "EZ" or "XG" in the name have a different incompatible RTC, which works only with patched commercial games.
