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).

to clarify, the GBC mode on a GBA has access to scaling hardware that the GBA mode does not.

hence why there is no solution to stretch out the image.

I'd be surprised if the latest version of Goomba done in 2019 couldn't stretch the screen
SURPRISE!
:D

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?
Yes. https://datomatic.no-intro.org/

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.

EverDrive GBA / Re: OMG MY BATTERY WENT DRY!!!!
« on: October 26, 2020, 08:30 AM »
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.

11
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.

12
Not a great idea. There already is a flashcard on the market that does this and its constantly being criticised for that because if the inherit issues this comes with. The Ezflash omega does write the contents of SRAM to the SD card once it changes (I.e. the in-game saving has concluded.)

But write operations to the SD card take time and when you interrupt this process (by powering off the console), Filesystem corruption will occur. Yes, waiting a few seconds after the process has finished in-game is not an issue at all, if you know to do that.

I understand you would want this as an option (not the default or even the only method) but I do see an issue with implementing this as an option for people who don't know the inner workings of these things: people *will* enable that option and people *will* suffer Filesystem corruption and lose their saves. They will be disappointed or even angry and they will fault the everdrive for an "unreliable" option.

The effort to implement this and the risks/downsides that come with such an option far outweigh the benefits it has, in regards to the average consumer IMHO.

I am not sure if the everdrive does it the same as emulators, but you could try putting the save ID string into your ROM image:

Quote
Nintendo didn't include a backup-type entry in the ROM header, however, the required type can be detected by ID strings in the ROM-image. Nintendo's tools are automatically inserting these strings (as part of their library headers). When using other tools, you may insert ID strings by hand.
The ID string must be located at a word-aligned memory location, the string length should be a multiple of 4 bytes (padded with zero's).
  EEPROM_Vnnn    EEPROM 512 bytes or 8 Kbytes (4Kbit or 64Kbit)
  SRAM_Vnnn      SRAM 32 Kbytes (256Kbit)
  FLASH_Vnnn     FLASH 64 Kbytes (512Kbit) (ID used in older files)
  FLASH512_Vnnn  FLASH 64 Kbytes (512Kbit) (ID used in newer files)
  FLASH1M_Vnnn   FLASH 128 Kbytes (1Mbit)
For Nintendo's tools, "nnn" is a 3-digit library version number. When using other tools, best keep it set to "nnn" rather than inserting numeric digits.
[..]Ideally, for faster detection, the ID should be put into the first some bytes of the ROM-image (ie. somewhere right after the ROM header).

EverDrive GBA / Re: Battery life without card inserted
« on: July 05, 2020, 08:57 PM »
It shouldn't make a difference because the battery is not powering the SD card. The battery on the PCB is used to power the RTC and the SRAM.

When the savegame is saved to the SD card (I am uncertain if the EDGBA X5 does that on boot or when loading a game), the battery doesn't play any role in keeping the savegames on the card.

That being said, the battery should last longer than three months, a few years should be the expected time for the battery to run dry (probably close to a decade, really)

EverDrive GB / Re: hotkey combination Everdrive GB X7
« on: June 16, 2020, 12:40 AM »
I just got the Everdrive GB X7.
I use it on a gba sp with ips screen mod and it works like a charm (excluding battery drain due to ips screen and the flashcart but i'm plaining to do a lipo battery mod).
I know it's a noob question but what are the key combination to save/load/toggle cheat on this card during game?
You squeeze the card. Its a physical button inside the shell.
