EverDrive GB / Re: does this work for GBC games ?
« on: September 17, 2021, 11:04 AM »
Given the new games need a working clock ,I dont think they can since trading requires ingame saves. I noticed the x3 model for pretty cheap along with the x5, but again pokemon requires working ingame saving so im not sure if they could trade.

The X3 does support in-game saves, the difference between the X3 and the X5/7 in that regard is the fact that you need to return to the everdrive menu by pressing the button in the cartridge in order to trigger writing the savegame to the cartridge.

EverDrive GB / Re: GB X5 - RAM & Saving Errors

Nintendo found a way around certain devices running on hardware they barred them off from being accessible. [..] but the SP with the 101 was heavily based off something different making the X series not run on it.

So Nintendo managed to specifically block devices on the Gameboy Pocket and the AGS-101 two decades before they released? Damn Nintendos time traveling Ninjas.

If the battery inside the cartridge is dead, you should replace it to continue to be able to save progress. The save memory of the everdrive is volatile, so it will pretty much instantly lose the content when the system is powered off.

That's why the everdrive GBA has a user replacable battery - so you can replace it once it's empty.

Oh I have original EDGB in my collection. Tell me more about transfer pack 'hack'?

EverDrive GBA / Re: Game compatiblity (X5 vs ODE)

Presumably some Anti Piracy measure they overlooked. Try the European version, that works fine on the no-definitive edition and should also run on the ODE.

EverDrive GB / Re: Everdrive GBx3 to Mega Memory Card
« on: March 07, 2021, 09:55 AM »
I don't think you'll be able to do that with the x3 because you need to have to have the game loaded  and then overwrite the SRAM using the mega memory. But I believe this would require you to boot the Gameboy to the mega memory menu which will not allow you to boot the game.

I can see this working with the x5, x7 or the old EDGB (non-x-series), but not the x3.

EverDrive GBA / Re: Everdrive GBA X5 - Classic NES Series games
« on: February 16, 2021, 10:15 PM »
I think the issue might be copy protection. The NES classic series had excessive Anti Piracy measures and - as far as I understand - the everdrive patches these on the fly. If it does, and if it uses the checksum for identification, the newly verified dumps might not be implemented in the firmware (yet).

There is no other gb/gbc emulator available for the gba hardware.

EverDrive GBA / Re: How do games save on the GBA X5 Mini?
« on: January 03, 2021, 11:39 AM »
Have had mine for over 8 years now!
So you got an everdrive GBA X5 in 2012, about 4 years before it released?

New Mario Kart 64 rom hack I made that expands Battle Mode with new game modes, score modes, adds cpu bots, and many other things.

Battle Kart 64 v1.0

What riom verison do i need to patch this to work? i tried with my romm copy but got a error about a mismatched checksum.

Please help me out, i want this a lot.

EverDrive GBA / Re: @ Krikzz. GBA X7 planned?
« on: December 28, 2020, 12:23 PM »
If I X7 Pro came out I wonder if it could fit a bigger SD card holder and no longer a micro SD one that fits into a small gap, the good ol SD2SNES era and Super Everdrive ones were the most reliable and easiest to use. A big flaw with the EDGB line is the card is too tiny to keep getting out I'd love one that pokes out of the bottom even if it did look a bit jarring.
You're weird, my mother has forbidden me to hang out with you from now on.

Pretty much no one but you would want the sd card to stick out. "regular" sd cards have basically been phased out except for digital cameras by now and those are usually triple the price of micro sd cards so I can't see switching to plain sd cards being a smart choice for multiple reasons.

Besides that, how often do you take out the microSD currently? My sd cards rarely leave the flash cards at all.

EverDrive GBA / Re: Known good save types for tested games?
« on: December 13, 2020, 10:44 AM »
Yup! That was it, bad ROM. Is there some master database where I can confirm hashes if I notice issues so I can ensure my ROM isn't the issue?

Ok seems it's corrupt. I have no idea why flash save files are affected by the battery.

Because the everdrive - like pretty much all other gba flashcards - only has an SRAM chip, it doesn't just come with all the different memory variants equipped. Whatever the game itself is addressing doesn't matter here, because the flashcards reroute the calls to/from save memory to the SRAM chipe everytime.

Haven't used the RTC battery since the day I got it 5 years ago, still going strong...
I am almost certain you did. First of all, the battery not only powers the RTC but also the SRAM. Second, the RTC circuit is probably powered despite you not "using" it in any game.

It's strange that the SD2SNES doesn't got the same complaints as the Ezflash. Maybe it's better at preserving the save file by keeping backups?

I assume that's the nature of home console vs handheld. When you save on the GBA, you already have the console in your hand and you can reach the power switch pretty quickly.
when you save on the SNES, you then have to get up and reach for the power switch or reset button - probably giving the unit enough time to write the save.

I also guess that monitoring the SRAM would take additional power for the FPGA when it is running, which is irrelevant for home consoles but is more important for handhelds - but that's just a guess.
