Hello, Tempers. I have recently purchased a GB USB 64M Smart card with the intention of reliving my childhood by playing the Pokemon Games. I completed Pokemon Blue and had a blast in doing so, but when I started playing Pokemon Gold, I noticed something: there is no rtc (real-time clock.) I understand the smart card cannot have rtc because of lack of hardware, which is why I am posting this thread.

About a year ago, I had an issue with Lameboy on my DS in that it kept saying TIME NOT SET on the continue screen and prompted me to reset the time each time I loaded the game. I was wondering if it is possible to replicate this with the smart card so that every time I boot the game, it will allow me to set the time so I can set it to the time in which I am playing (which would result in me having the ability of catching certain Pokemon that appear only at night, etc.) each time I power on the game.

I also noticed that the time does not change as I play. I set the date and time to MONDAY 4:13, played for 18 minutes, saved the game and noticed it still said MONDAY 4:13 before powering off my GBA SP. I also tried this in my GBC (not like it would change anything) and am wondering if there is a way to link the accumulation of play time with the progression of real time through emulation of some sort. I have no experience in hex editing and patching, so I would greatly appreciate if a) someone could guide me step-by-step in creating such a patch, or b) if someone could provide a patched ROM for me.

Thanks for reading, and I hope someone finds a solution! In the mean time, I'll have to hold back from playing GBC because it really won't feel nostalgic without the in-game time changing.
P.S. I can change the time if I were to copy my save file onto my computer and run it in VBA, but I don't want to do that every single time I feel like playing Pokemon Gold as it would be more of a chore than a nostalgia trip.

I see. You could replace that one fucking battery, though.
Not too sure if that's possible without losing the save, but when you're done, you're good for another 5-10 years.
CR2025 batteries FYI.
It's not hard to do, I consider myself technologically impaired and managed to swap it succesfully without soldering.

You're missing the point. I have a save file from nearly 10 years ago on that with over 133 hours on it and I do not wish to lose it.

If it's that important, you might want to consider investing in a flash linker. I believe they were able to back-up and restore SRAM as well, but better read up on those in detail before ordering one.

I was actually considering making one myself, but for the time being I'd really appreciate the ability to play Pokemon Gold with rtc-esque features. If anyone has any solutions, please let me know. :)

But wouldn't you still be unable to use your save, even if you got the game working on your 64M Smart Card?

Oh I finally got it. You want to start a new game but keep your old game save. I'd suggest buying a second copy of Pokeymans, considering the 64m Smart Card lacks an RTC-chip.
Edit: Awesome, if you happen to have an N64 flashcard like the Everdrive or 64Drive, you could also try this: http://lacklustre.net/n64/agbd/

You can't add RTC to the USB 64M SMART CARD. At least, there's no known way to do that.

Only thing you can do is:

1. buy a linker
2. dump your Pkmn Gold save
3. change the battery
4. burn it back on the original card
5. ????
6. profit!!!

Again, when I finish my game I'd like to back up my save file so I can keep it forever and use it on emulators, especially on GameYob for the DS which allows for wireless multiplayer. So I really just want to play on my smart card.

I was hoping that the rtc FEATURES (ie. the time of the day changing every time the in-game play time changes) would be made possible. Also, I was hoping to be able to reset the time each and every time I reset the game so I can change it to the current time.

There's a patch to do that. It'll "fake" the RTC to ON, but you'll have to set the time manually every time.

oh DAMMIT!! Do you know anyone who would be able to do this for Pokemon Gold? I would appreciate that SO much.
GameBoy ASM hacking? You're better going out mining for gold, there's more chance in finding that, than a skilled ASM hacker... especially nowadays.

EDIT: Waaait a second, Pokemon Yellow doesn't have a Real Time Clock feature - that was introduced in Pokemon Silver and Gold!
Indeed it doesn't, and that's why everyone in this thread is talking about Pokémon Gold.

  • S @ salazarcosplay:
    @Xdqwerty I like how the game had the middle ages 1000AD, the dark ages 600AD.It was great seeing the post robot apocalypse 2300 like Terminator and enter the matrix. some of mad max and fallout. 2300ad though it could had used more elements instead of just a generic ai uprising. It was a great idea for their judgement day to be 1999 Y2K.

    -great additions if they would have made an expansion or dlc in my opinion would be finding out humans trapped in a matrix -

    a follower having a cyborg character living tissue over metal endoskelleton like terminator, and the synths from fallout
  • S @ salazarcosplay:
    4After Zeal fell it would have been good to see more ancient eras. Perhaps Sumeria based in one area, then Egypt based in another area, Greek based in another area, then roman based in another area before the middle ages.---------

    ----between 1000ad and 1999 is a big gap they should have had the age of revolution like the american and French Revolution

    then the cowboyy era in one area of map and the Industrial revolution/age of enlightmentthen a ww1 and ww2 and a cold war era

    they could have added 75,000 bc like assassins creed. zeal was already establish in 12, 000 bc , soething before the kindom rose
