Hacking Everdrive GBA X5 Pokemon Yellow problem

[Xpyred]

I just received my Everdrive GBA X5 today. I mainly bought this to play Pokemon Yellow, Crystal, Leaf Green and Emerald. I have other roms on the everdrive as well. Anyhow, I tried my Yellow rom which i edited to have all 151 Pokemon available. When i save the game normally, it says it saves. I turn the system off and turn it back on and Yellow keeps starting a new game. Now i tried Legend of Zelda and Mario Land 2 and those games seem to save and start normally but Yellow does not. I am afraid to try crystal and leaf green. What am i doing wrong?

I have same your flashcard. I read up on Krikzz forum said that all GameBoy and GameBoy Color games (Pokemon) don't support on Everdrive GBA X5. Don't play Pokemon GB and GBC games on Everdrive GBA X5 flashcard that don't have Real Time Clock support for GB and GBC, only apply to GBA games. I'm sorry it don't work for us.

But you can play old GB/GBC (No Pokemon games due to Real Time Clock problems), and NES games on Everdrive GBA X5 without problems.

You have to buy Everdrive GB flashcart to use old GB/GBC games for Pokemon can save on it without problems. Due to Real Time Clock feature is different between Everdrive GBA X5 flashcard and Everdrive GB flashcard.

This is just a quirk of Goomba [Color]. The short of it is, you must press L+R to open the menu and wait a second for games with 32KB SRAM to save properly.

For the long of it is, Goomba (along with PocketNES, SMSAdvance, etc) were all written to support maximally using the space on the 64KB space of GBA flashcarts. However, they also originally (due in part to being based on PocketNES) have an 8KB SRAM block that's written to directly in the 64KB space. So, games that use 8KB SRAM or less on most the emulators have saves that just work. When it was realized that this wasn't enough for some, the solution was to just have SRAM saved/restored on the L+R menu which at the time was something you did anyways to exit the emulator.

At this point, though, some of the emulators (like some of my forks IIRC) have fully abandoned the whole 8KB SRAM area carved out of the 64KB because there's little reason to have SRAM that works some of the times. Better to just require L+R and a one second wait for it to always work. I don't recall which emulators or forks this apply to of the PocketNES lineage, but it's just general good advice.

So, if you are pressing L+R and it still isn't saving properly, then that's an actual issue.

better yet, show pokemon crystal/gold/silver to see if the RTS works, a pokemon yellow video is cool too though

we modified some code of emulators, the L+R exit is saving properly. and each gb/gbc/nes rom has individual save file of themselves.
