I'm currently trying to write some GBA RTC tests for the S-3511 real time clock (Used in commercial GBA games).
The EZ Flash Omega's PCF8563 RTC seems to have a translation layer for the S-3511 chip (in particular, the actual clock and calendar) however I'm having difficulty getting the alarm, minute and frequency interrupts to fire (at all).
Here's the data sheet for the S-3511(A): http://www.sih.com.hk/sih_eng/products/ic/pdf/s3511a_e12.pdf
I'm wondering if @EZ-Flash2 or someone else could provide some information on how much of the RTC is implemented as I have suspicions that the IRQ REQ feature itself is not even implemented and that would be why I'm having difficulty getting any of the interrupts to fire.
