gbc4nspire Bug

[DJ Omnimaga]

(should that version of gbc4nspire be added to the archives since the original was by one of our staff?)

That's fine with me

[DJ Omnimaga]

Ok, I think I'll include it with the current version.

Ok, I have a "problem" or maybe a bug or maybe I am getting worried for nothing.
In Pokemon Cristal the clock is very strange. I don't expect it to be accurate but
- the minutes are always at 58
- the hours increase by one every <random long number> (so it is always night, but it used to be day at the beginnning)
- the day changes sometimes I don't know how
- "Mom" says she lost the notice to set the clock

How is it working ?

Ah, I never really implemented support for the clock that is used in some cartridges. It would have been hard to do with the way I implemented memory reads, so I didn't do it.

[DJ Omnimaga]

Was the clock built-in the GBC or was it part of the cartidge, like how they added extra chips in SNES ones? I didn't even know GBC games used any clock or stuff like that.

It was part of the cartridge. The games had to interface with the clock by using memory reads/writes, and that didn't work with my emulator because it didn't support trapping reads or writes to that area of memory (each byte in that 8KB range does the same operation)

[DJ Omnimaga]

Ah ok thanks for clarifying. Do you know if it will be added in the future? (Although I understand without the source it's quite hard X.x)

[calc84maniac]

The only way I can see it happening without a complete rewrite is by some sort of hackage that assumes that games will always read and write the first byte of that area, and the emulator would check/update that byte semi-regularly.

[Hayleia]

But if you don't have any clock, why is the hour changing sometimes ?

Well, I think it's just treating the clock interface as actual memory, so it's probably reading the time from the RAM on the cartridge instead.

for that reason, you can't play HM1.
Also, for pokemon crystal, wasn't there a combination to change the clock?

Normally, when you talk to your mother, there is an option to change the clock. But she says she lost the notice

[JosJuice]

I think there is a secret way to change the clock on Gold and Silver but not Crystal. However, DST adjustments are possible on all three games by talking to mom.

well, there was a way to change Days with gbc4nspire (2.1) but IDK about the current version.
Go to pokegear, set it so you can see the days(Like monday), hold x button (you, know, speedhack), and scroll the pokegear to next page and go back to day stuff.
