Homebrew Emulation GameYob, a gameboy emulator for DS

[VMM]

I was playing pokémon yellow and the emulator simply started loading an older save.
I had already not only saved, but also loaded from a further point of what I'm now.
Anyone has an idea what might have happened?

- Do you use save states/suspending?
- Is autosaving enabled?
- (If not) When you loaded your "further progress" file earlier, was it after selecting "reset"? Or was it after exiting and reloading the rom?
(selecting "reset" will not copy the updated save file to the sd card.)

The only way that could have happened is through some kind of user error. When autosaving is disabled, the saving process can be confusing.

Does Gameyob have the green background thing like the original gameboy?!?

Nope, it uses either monochrome colors or gbc-colorization.

I haven't got around to it.

Whoops, didn't notice it was you. Okay, keep up the good work!

I'm new to this so I don't really understand how this works. Do I just put your emulator on a flash cart on then plug in and play, or do I need a custom firmware?

Oh yeah, Drenn, have you fixed that one problem we emailed about? Where when you use NiFi and you save, it doesn't actually save? This can cause a loss of data with pokemon, I was hoping that inserting and reinserting would still allow the the game to save.

No I haven't, currently the best solution is to use 2 flashcarts... I mean, when you have to physically remove the cart while the game is playing, of course that's going to cause problems when it's time to save.

Well it depends on the flashcart and etc. Mostly you can just put the emulator & roms onto the flashcart, and start it up and it'll work. Some flashcarts have custom firmware, like AKAIO for the AK2i (but don't get an AK2i unless you're using a ds phat or lite). I'm sure there are tutorials around for specific flashcarts.

That explains a lot, thanks
I used the reset option and did not have autosave enabled.
Game is saving fine right now, thanks

RIP ;_;

It's not dead! Honest! I just don't have near-infinite spare time anymore. I actually worked on the UI a bit over the weekend. It's staying text-based, but I can at least pretty it up with colors and stuff... I also want it to run in parallel with the game. This isn't in the repository yet, the "run in parallel" thing needs to be ironed out.

Missed this comment somehow. I suppose I could, but it'd probably be uncompressed.

Take your time
if it doesn't work
Then don't worry
you did your best

At least it is open-source! Thank Drenn for that blessing!

No joke! This thing represents a lot of work, and a lot of people appreciate what Drienn and the handful of others have done. We need Lemonboy to revisit this a little and update how it handles the HuC3 emulation, mostly how it emulates the battery the Robopon games had.

Does exit without saving at least save the sram? It doesn't seem to be doing that for me. I don't really want to save and exit as writing a savestate is very unreliable and can cause the emu to freeze. File writing functions have always been somewhat broken with my flashcart. I tried formatting my sd card and it got better for a while but now its not working well anymore.

No you're misunderstanding. "Exit without saving" doesn't copy the sram. "Save & Exit" copies the sram. "Suspend" copies the sram and makes a save state.
I'd highly recommend autosaving for the games it works well with.

i just want to thank you as i could play good-old tetris with my wife with our ds and ds lite with only one flash cart. wireless connection of gameyob works perfectly well with tetris.
