So I just ordered one of these, don't know if it's legit or a bootleg, but does anyone have any experience with these things, do they have any flaw or something? Never had a gba flashcart, so I wouldn't know what to look for.

As far as I am aware there have never been any clones of the EZ4. But yeah it is legit, the EZTeam sent us one last year

Unless you manage to find an old second hand M3 or G6 or EZ3 (note not a EZ 3 in 1) then you are unlikely to find a better GBA flash cart out there, though the EZ4 is by no means bad and you should be able to play just about every game in the GBA library flawlessly.

It is troubled by the same games that trouble all flash carts (give or take RTC for those carts that have it)

Also some games you might want to launch by holding L and pressing A rather than just pressing A (it forces a hard reset which sorts some issues).

You need to patch games to run. The EZTeam provide a program called EZ4client for this, there are various alternatives that people have made in recent times and I suggest every GBA flash cart owner and emulator user has a copy of GBATA from http://www.no-intro.org/tools.htm to hand.

I am not sure what else there might be to say, I suppose I better cover the NOR/PSRAM stuff though.
GBA games need fast memory to run from, faster than NAND memory as seen in SD, CF and general NAND memory chips. NOR based memory and RAM is fast enough and the EZ4 has one of each.
GBA games other than the shrek films which were only dumped the other month ( http://gbatemp.net/threads/undumped-gba-shrek-videos-analysed.404837/ ) went up to 256 megabit (32 megabytes, the terms will get swapped endlessly in discussions of GBA flash carts so just remember to divide by 8), though most are 128 or less; there is a full list of the 256Mbit titles in buying a flash cart in 2013 post I linked.
The EZ4 aside from the lite compact (which has less) and the lite deluxe (which has more) has
128Mbit of RAM, this is fast to write but loses the data when the power goes (your save is elsewhere and what the battery is responsible for). When you press A (or L and A) in the game selection list this is what you will be using.
256Mbit of NOR, this is slow to write and has another quirk but it is there until you delete it. You go through this menu first when you go to select games and any games written to the NOR will appear there. On the NOR screen start should format the NOR and select will delete the last game on the list (this would be the quirk -- NOR in this arrangement is first in, last out so if you have roms 1,2,3 and 4 and want to delete 2 then 3 and 4 will also be coming off. In the file selection menu then pressing select should give you the option to write a ROM to the NOR. You can write small games if you want a slight speed boost in launching if you like but most prefer to have a large game on there (personally I am not a fan of the offerings from the 256Mbit library but to each their own).

Well, if this is going to be a catch all, I might as well add a couple of things. If you want the sleep function that some games support to work with the EZ4, you just need to change a value or two in the ROM with a hexeditor. The values that need changed in most games are recorded online, a quick google search will bring them up. As for games that don't support it all together, there's patches for that.

As for saving, the updated save won't be written to the SD card until you return to the menu. You can either just turn off the GBA then back on again to have it write or you can patch the ROMs to return to the EZ4 menu with a button combination. The sleep patches and soft-reset patches aren't universal, some games will be picky about which ones you use, some might not work with any of them.

Sounds alright for the microsd version, just get this or wait to see if kirkzz makes a everdrive-gba?

EZ4, if you're willing to do a small amount of leg work, works great. Any extra functions (soft reset and sleep mainly) you have to modify the ROMs for. If you want something solid now and don't mind doing a bit extra (or going without those functions) then have at it. Everdrive could be nice, but we don't know when (or if) it'll be out or what all it will be capable of. It's even useful for dumping DS games with Wooddumper Slot 2. In the end, it's up to you. Nothing fancy but I've had great times with mine the past few years and it's still going strong.

The GBA everdrive in some form exists, a video from last month on progress - obvious and annoyingly no info on any kind of a release date/window on it.


This is what makes me hesitate buying the ez-flash iv again as I didn't much care for the design of it compared to how everdrives work.

And this second video was just posted on the 6th so there's definite quicker progress now.

I own one (bought from AliExpress, received about a month ago) and I love it. Replaced my dead-battery M3 Perfect with it to start playing GBA games for the first time in many years.
