(and yes, I’m sort of cheating with the above screens, since the game could be played even without the RTC, but some events would not have worked as designed without it, so it is a *real* improvements 😉 ) Similarly, the new code allowed to say goodbye to this annoying messagesĪnd made Pokémon Ruby / Emerald / Sapphire at last fully working After some work to add the correct GPIO hookup into the driver, I was finally greeted by Sennen Kazoku getting in-game It turned out that in my previous attempts on this, I had misread some of the bits of info presented at GBATEK. Since the port was quite well documented (mainly thanks to the great reverse engineering job done by the nocash guy) and the RTC improvement was often requested on the Bannister MESS board, I decided to take (again) a quick look to see whether this time I could manage to make the RTC work. The missing implementation of the RTC comms was also the reason why Sennen Kazoku was stuck on the following screen The main usage of the port was the routing of the RTC in Pocket Monster games, the Rumble feature of Drill Dozer and the Gyroscope sensor of Warioware Twisted. While going through my notes and partially developed implementations, I stumbled upon a bunch of notes about the “General Purpose I/O port” of the GBA, a bunch of pins connected to the ROM on the GBA cart PCBs which allow the system to serially transfer bits through the cartslot.
Since I got stuck with porting my custom EEPROM implementation for Genesis/MegaDrive towards the core one and since updating software lists with PCB info is valuable but not very exciting, I was searching for some not too complex but still rewarding emulation task to occupy my weekend.
