Why use a real-time clock (RTC) in a Game Boy game?
- Resource replenishment over real time deters binge play and beat-then-refund
- Cosmetic changes for time of day or holidays
- Spaced repetition in language learning games
- For non-game applications such as a personal organizer

Why avoid RTC in a Game Boy game?
- Increases cartridge cost
- Reduces backup battery life
- Players with screen time limited by time of day or day of week miss important in-game events
- Reduces exposure of your game to viewers of speedrun streams

You have 5 bits for the hour of the day in a clock chip register. Do you just use a binary representation from 0x2x0_0001 to 0x2x1_0111?

No. That would be too easy. Programmers might use your hardware, and that would never do.

So you make bit 4 mean add ten to the value in the lower four bits, and document hour 23 as being hour 13+10.

And for kicks you do that for the 5 bit month number register, too. Because 4 bits storing just 0x2x0001 to 0x2x1100 would just let those pesky programmers in, again.

What on Earth were these chip designers on? BCD, I could understand. Even giving midnight the value 8 I could understand. But this scheme is just mad.

New Blog Enrty: With a slight delay, the ZX81 can read and set time using the RTC. Time flies when you're having fun, but the ZX81 might need a little extra time to catch up! #ZX81 #RetroComputing #RealTimeClock #VintageTech

Found this odd RTC cartridge for Atari ST. Will have to check the battery, and find software out there. 🤔
