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?
Please put the roms in the root of SD card, not a folder.
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 ??
ok thanks I solved
What is your solution?
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?
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
How can i put codes?? like pokemon emerald.
I have the firmaware 1.77 and yoshi island get black screen…. why?
Which mode did you use? PSRAM or NORFlash? Did you patch the rom with ez4client?
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.
Figured it out – hold L and then press A to start the game. This forces a hard reset and the game will work.
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 ?
which mode while you got the blank screen? PSRAM or NorFlash?
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 ?
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 ?
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.
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.
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.
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?
what the filesystem did you format the microsd?
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 ?
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.
glad to hear that, we will improve the product quality continuously.
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.
Can you run gameboy classic or color games on Ez flash 4?
yes but only buy emulation and the emulation is not that good and the emulator is not made by ez flash
I tried using goomba color, but a lot of games don’t work, do you know any other emulation?
Running on Gamboy Micro?
