EZ-FLASH IV

  • Virginio Vaccaro

    I bought a prejudice your ez cartridge 4 for gba I inserted a formatted sd a fat 32 to 16 gb of space but I can not put so many games at one point but then I add games in gba displays only empty folders why is this happening?
    thank you

    • ezflash

      Please put the roms in the root of SD card, not a folder.

      • Virginio Vaccaro

        thanks for the reply, I tried to copy the Rom in root but nothing to make me reads max 75 rom just add a new rom I displays an image of a yellow folder
        you have other suggestions ??
        thank you

        • Virginio Vaccaro

          ok thanks I solved

            What is your solution?

      • Wong Man-Fung

        How do I put more than 78 roms in one directory? I am placing them in the root of SD card, and still doesn’t show more than 78 roms, beginning from 79th rom, it becomes an empty folder and I can’t enter the game. Please advice. Thanks

    I bought this model 1month ago…
    but when i started pokemon it say “the international battery has run dry ~~~”
    it can’t support RealTimeClock?

    • ezflash

      EZ-FLASH IV does not support RTC of pokemon, only EZ-FLASH II series supports RTC. you can use a RTC patch with the rom

  • Luis

    How can i put codes?? like pokemon emerald.

  • Luis

    I have the firmaware 1.77 and yoshi island get black screen…. why?

    • ezflash

      Which mode did you use? PSRAM or NORFlash? Did you patch the rom with ez4client?

      • sam

        Same problem. Rom is patched and tried using norflash and psram – seems to be affecting several games. I also have an older Ezflash iv with minisd running firmware 1.72 and the games all work perfectly on that.

        edit: correction it works from norflash but not psram but why? On my old ezflash iv with version 1.72 it works with both.

        • sam

          Figured it out – hold L and then press A to start the game. This forces a hard reset and the game will work.

    Hi,

    I have latest kernel on EZ Flash IV micro sd. With a lot of games I got a bank screen at startup.

    When putting the same sd in another EZ Flash IV micro, it works fine.

    Reinstalling the firmware on the faulty one does not change anything.

    However, I observe that reinstalling the firmware does not erase the previous configuration as some preferences are saved (language etc…). I thus guess that the faulty file or so is not resetted when I reinstall another firmware.

    My question is : is there a possibility to completely erase a firmware to start again from a clean sheet ?

    • ezflash

      which mode while you got the blank screen? PSRAM or NorFlash?

      • J Anonymous

        Hi, I tried both. And result is the same. As I said, on another cart, it’s working out of the box. And problem is only present with few games like the Donkey Kong series. So I want to erase all firmware installed and reinstall the latest on a “clean sheet”. Is this possible ?

        • ezflash

          The procedure of press R update firmware is erasing at first, then write the new firmware.

          second question, the game except donkey kong series are not faulty ?

          • J Anonymous

            No there are other games which do not work. I’ll provide you with a list this evening.

            As I said, after the firmware upgrade, some settings are kept (like language preference). Hence I think that some configurations are not erased while updating the firmware.

          • J Anonymous

            So here’s the result of my testing (v.1770) :
            – DK : white screen after Game Boy logo
            – Super Mario Advance : white screen after Game Boy logo
            – Zelda a llink to the Past : white screen after Game Boy logo
            – Pokemon Leaf Green and Fire Red : white screen after Game Boy logo
            – NES Classic Pacman : OK
            – NES Classic Bomberman : OK
            – NES Classic Zelda 1 and 2 : OK
            – NES Classic Super Mario Bros : Not OK, black screen

            Here below I provided you with my test results.

  • Silence

    Hey guys, im new to EZ flash hardware and software and will be buying one soon. But i have a question that is a little off topic and am hoping the experts out there might be able to help me. I’m wondering if there is any hardware and software like the EZ flash for the Playstation one ie a memory card that i could load up with playable Roms. Any point in the right direction would be much appreciated. Thankyou.

  • marc

    Hope you can help.
    I am using a ez flash iv on a DS.
    I have applied ezfla_up.bin. When I put the cartridge in and hold down R it successfully updates.
    this proves the cartidge works and it can read the micro sd i have.

    I then put a game on using the EZ4 client.

    The cartridge then only shows a black screen in the ds.
    If i put the cartridge in without and SD it tells me cant find disk.

    why do i get a black screen when i have th sd card in?

    • ezflash

      what the filesystem did you format the microsd?

    Hi,

    In my comment here below I provided you with the input you required from me.

    Can you have a look and keep me updated on how I can troubleshoot my issue ?

  • J Anonymous

    My problem (blank / white screen at game start) is now +/- solved.
    It was not a software, firmware, roms, patching or even card issue.
    It was a product assembly issue. After some reading on the Internet, I tried the “paper trick”.
    It somehow improved the situation where more games where launching. Only 2 were still causing issues.
    So I tried to add some paper layer / remove some / … and mitigated results. After 1 hour of trial and error I found the correct “thickness” fixing the issue.
    So, root cause = poor assembly and inexistant quality control.

    • ezflash

      glad to hear that, we will improve the product quality continuously.

  • Wong Man-Fung

    How do I put more than 78 roms in one directory? I am placing them in the root of SD card, and still doesn’t show more than 78 roms, beginning from 79th rom, it becomes an empty folder and I can’t enter the game. Please advice. Thanks

    • You don’t, and I doubt they’ll be updating the firmware to make it possible. Make sub-folders and put some of the roms in that.

      • Wong Man-Fung

        They fixed it in 1.78

  • Adrian Blag

    Can you run gameboy classic or color games on Ez flash 4?

    • Kevin McAbee

      yes but only buy emulation and the emulation is not that good and the emulator is not made by ez flash

      • Adrian Blag

        I tried using goomba color, but a lot of games don’t work, do you know any other emulation?

    Hi,
    What about problem in the picture?
    Latest version of EZ-Flash 4.
    It occurs every time (very rarely works ok) I power on console – there are 2 nag screens – attached.
    I also tested the battery – perfectly fine – 3.2V.
    Saving works but worst is that everything that was in stored in nor memory is titled with Chinese and does not want to load up…
    This started for me on 1.77 firmware then I tried downgrading to 1.76 (same crap). Now I am on 1.78 and same story…

    Thanx for help 🙂

    • ezflash

      it seems the solder point of the battery was broken. please try to test if you have the electronic meter

      • Wojciech Szczetyński

        First I though that – If it be like You are writing it would not keep the save / it would not be saving.
        Visual and “by hand” inspection did not indicate any problem, there was no obvious loose connection. Then I took multi-meter and started “playing” with it around pcb to find where traces from battery goes. Suddenly when measuring directly on battery solder points to pcb I got 0V ;]
        And there we have it cold joint… Sometimes working sometimes not, but why saving was in general working???

        The problem was that battery pins (“metal legs”) were not pre-tinned. Not doing it result in bad connection/soldering. BTW soldering was also crappy there, too much of it – no pro.
        Desoldered battery, remove old tin with soldering wick. Scrapped a little bit battery “legs” with file, pre-tinned it and soldered to pcb and voila 🙂 working.

        BTW I bought it from Aus reseller and he got many of negative comments on this product so it looks like bad batch…

        Big thnx 4 pro help 🙂

  • Alfonso CC

    is there a official guide pdf o document for use of ez flash iv? thanks

  • oneWonders

    There is a problem with carts revision 0217 🙁

    Either the NOR is damaged or there is a problem with the new revision concerning NOR which needs to be fixed in a firmware update.

    Mother 3 does not work – it copies to NOR fine but when you try and run the game, it gets as far as the GAMEBOY PLAYER logo screen and then crashes to a white screen with lots of noise.
    For a video of what happens, see: http://s000.tinyupload.com/index.php?file_id=43628528947986895835

    Unpatched ROM MD5: af8b0b175f7ec8914cb87b3161ba1aaa

    The ROM has been patched correctly with EZ4_20140306 ( only the Save Patch checkbox option, leave the reset patch unchecked.)

    Patched ROM MD5: b044de4106b0f296d34a46a869872233

    If this is a firmware issue, rather than faulty NOR chips then please could there be an update to fix this.

    The game works fine on other revisions (for example ‘rev 1316’ and ‘rev 2516).

    Thanks!

    • ezflash

      I tested the mother 3 game, patched rom MD5(MOTHER3.gba)= 5552815787e5983af6b40253e34e9d5,file size 33,554,432 bytes , it works well.
      the rom is japanese version with chinese translation. and the card rev is 0217.

      • oneWonders

        Could you please test with the original Japanese ROM that I stated above?

        Meanwhile, I will search for the Chinese fan translation to test.
        Is the md5 you listed that of that of the fan translation or when the ROM has been patched via EZ4_20140306 ?

        Thank you

        • ezflash

          Your can contact your dealer for a replacement, or contact us directly.

          • sumitgood

            are you working on a fix or is it not possible?

        • sumitgood

          I also tested this and same issue… md5 is exactly same as what he said but mine crash also. Surely its a hardware issue?

      • oneWonders

        OK, I tested with the Chinese fan translation that you mentioned (for anyone else reading, they list the save-patched md5 hash).

        Unfortunately I still get the same issue, as seen in the video in my original post.

        I would suggest that this means my cart has a faulty NOR chip with bad sectors, what do you think?

        Please could you increase the quality control of the NOR chips, as I have seen two others with this exact same issue with this game and many others with other NOR corruption issues.

    Hi. At me here what problem. Run my GBA with EZ flash installed. Gameboy
    starts fine, there is a window Item describe and nothing more. After a
    few seconds the screen is covered with black stripes. Use a micro sd flash
    drive of 1 Gb, game patch, but nothing helps. Is it a malfunction?

    • ezflash

      This issue is microsd card did not be detected. Please check the microsd card format, FAT16/FAT32 are acceptable.

      or change another microsd for a try.

      • Maxxx

        Thanks for the advice! Still the problem was the micro sd. Was replaced by another and everything worked as it should.

  • sumitgood

    Mother 3 issue, can you tell me the Chinese Rom file you used to get it working on ez flash 4… the jap/eng fail… and I’d like to compare the difference in the chinese rom to apply any fix to the eng .

  • Harunowa Winterfield

    Hey does it work with MicroSD cards or only with MicroSDHC?

  • Hagan Algo Mas Util

    Hey is the new 2.0 valid for my r4i gold?

  • xs4all

    Updated to latest kernal, deleted all my roms on my sd card, including the SAVER folder and start fresh. How does the save file created? After a game has been played, then restart for the save file to be created? Example of first game I tried, Advance GT2 (J), when I exit game, no save file is created. When in game, when I select SAVE, I get following error. ERROR, EEPROM WRITE 49153. What does this mean? I havn’t tested another game yet to see if I get the same message.

  • MSF

    Why can’t the EZ Flash IV run on the GBA (not DS) not directly GBC and GB Roms? The GBA is directly compatible to run GBC and GB Games without Emulation! See original Nintendo FAQ about GBA. So it should be possible on the GBA with Flashcard to load and run directly GBA, GC and GB Roms!

    • ezflash

      I understand your demand, it means you need a product not only a GBA flash card also a GB/GBC flash card. But the EZ-FLASH IV’s main control chip is insufficient to meets the requirement. the product which meets your demand maybe reveal in future time, but not now.

      • MSF

        Thanks for the fast answer! You could made a multiboot Flashcard, which can (re-) Boot into NDS/3DS, GBA, GBC and GB Mode. In this Way ONE Flashcard can play, without Emulation: [3DS, with Passme EG) NDS, GBA, GBC and GB Roms. I would buy it…

        • xs4all

          Yes it would be nice if EZ-Flash IV had some sort of switchable bios that tricks the cart into thinking it’s a GB/GBC that would be extra nice to play GB/GBC games on the GBA/DS.

          Your next best thing and it’s expensive is the EverDrive GB card. I didn’t have this card but I had something a little different back in the very old days and I still have it, google this “GB Bridge Flash2Advance”.

  • booch_95

    So I’m wondering if i have a fake EZ-Flash IV cart could someone be able to verify? Ever since I got it I thought it felt a little dodgy… mainly by the fact one of the capacitors just randomly fell out… top side just above the battery https://uploads.disquscdn.com/images/7c630c9500ec977b660cadc122a8d328010789fb8ea9fc905a8cb0c98a179f7f.jpg https://uploads.disquscdn.com/images/c783ff9eb95a6b8315fc0d1e6045a0949643827c649fac0168a65e8f64675292.jpg https://uploads.disquscdn.com/images/1f0e60b172b944213594fbf83d70e08974d3f58f2d7355fada1ef42c74a80b82.jpg
