What you may also find useful are hacked games that have been modified in the way that allows you to play completely new games. But we’ll bet you already have a couple of nice Nintendo ROMs downloaded from our website and an emulation tool wherewith you can run these ROMs. But in the 21st century, it can be quite difficult to find nice old-school games and stable emulation software that would allow us to play these games on modern computers. To begin with it would be unreasonable to expect users to manually patch RTC anyways.We all like retro games. So after a bit of tinkering, it seems that there is no simple tool to use to patch a gba rom and enable RTC, most 'rtc fixes' are game/hack specific therefore not really useful here. I haven’t done a full-fledged test to make sure everything is working, but Radical Red at least no longer gives the RTC warning. I changed rtcEnable(rtcFound) to rtcEnable(true) I was able to get it working for Radical Red by changing line 804 in GBADeltaCore -> libVBA-M -> VBA-M -> Util.cpp: If there is, then I suppose there could be an option per game to force enable RTC. There doesn't appear to be any effect on games that don't normally use the RTC. Some hacked games use the RealTimeClock even when the game they're based off of doesn't (ex: Pokemon Liquid Crystal), so we always have it enabled. Yeah, I noticed GBA4iOS uses the same method with a comment stating:

I wouldn’t expect the average user to patch their roms to turn on RTC. I’ll follow up and see if that actually does work tomorrow.Ī simple alternative to all of this though, is to have a master switch on RTC by changing the mentioned line of code (if on, force on. Reading through that code, it seems that whether a rom uses RTC is identified the same way the save type is, and something that rom hack makers should be changing -thing is, I could’ve sworn I manually patched roms using save patchers to enable Rtc in the past and it didn’t work. I wonder if this line could be changed permanently without negatively effecting other games.
