[3ds]Rtc supports games time of day but not day of week.

[Kirit29]

Was playing a rom hack of fire red that implements time of day events as well as events for the day of the week. There is a scripted encounter of a shiny spearow that appears on mondays in the first route. For some reason the spearow respawns every day. so im guessing the rtc implementation of the 3ds gpsp core doesn't pickup the day of the week and stays stuck on Monday. i checked if mgba has the same issue and it doesn't. The events work on their respective days like intended. Can this can be fixed?

Im on a new 3ds xl with latest luma and latest retroarch gpsp cia on latest firmware. thnx

fire red officially do not support rtc. the hacks do not have a way to force this either and most of them do not even override the flash type and rtc signatures that is mostly found in the binary file. core has to detect and force rtc to be enabled when such kind of rom is loaded, either through UI or something.

this is not a core issue per say, but the rom hacks themselves.

then how come mgba and vba emulators pick up the day of the week as the hack intended? if it was a problem with the hack it should have the same result on every emulator it is played on. I am genuinely curious.

not a fan of pokemon games, which seems to be the only games with rtc support (other than boktai probably but that needs solar sensor emulation as well which is not supported), but i've updated rtc emulation. no guarantee it will fix this specific but it should not break anything else.

Try to update once a new version is available in buildbot

question: does 3ds even have rtc support? how did you test "mgba" and vba on 3ds since they don't work on that from what i know.

Yes the 3ds has rtc. And...well mgba does have a standalone port for 3ds and endrift released a fix patch for the tool that adds rtc to pokemon games. Which makes it work on highly accurate emulators, ie Mgba and real hardware. As for vba i just meant the pc version.

well i just tried the recent nightly and it seems to have fixed the issue.

thats good to hear. if there is no more related issue, you can close this then.
