I'm posting here because the Wiki doesn't seem to have any info on the EZ-Flash 3, and I'm probably the last person on Earth to buy one, since everybody else has switched to DS, and the planet's EZ-F3 stocks are depleted. But there must be some people on this board who own one or have used one and are willing to impart their wisdom. ==== Version numbers EZ-Flash III for GBA/GBA SP 4 Gb (sticker) EZ395 2005.12 (reverse side of PCB) The software came from the retailer's webpage, in an archive named: ez3manager221_fix.rar When I start the software (EZManager.exe), the title bar reads: EZManager 2.21 (EZ3 OS Version:1.68 Driver Version :1.54 ) Yes, the odd spaces are in there like that, documentation and software are in Chinese or Engrish. I am using a Gameboy Advance SP (model no.AGS-001) ==== The first 24 hours The reader and cart came with a little card that says: "Please visit http://www.ezflash.cn to get the newest software support." I had been warned however, that this particular version would only work with the specially fixed software as above, so I didn't try to update or get the latest version. Only after an hour of playing around with the software did I happen to turn the little card around... "To secure your saver, please connect the EZ Writer to PC that is power on and insert your EZ Cart into EZ Writer to Charge the battery about 8 hours before you begin to use your EZ Cart first time." Whoops... I actually tried it out straight away before I noticed the card had stuff written on both sides... hope that didn't break it. I have noticed that many USB devices have their LEDs lit even when the PC they are connected to is turned off, so I am not sure leaving your PC running for 8 hours straight is really necessary. I did plug it into the rear USB port on my PC, and left it running while I was at work. Regular saving works now, at least in Double Dragon and Final Fight. ==== The Questions 1) When I try to use Instant Save (L+R+Select+B) the game crashes. What's the trick to getting Instant Saves to work? Do I need to study a compatibility list, or verify my ROMs? 2) When EZManager.exe is running and the Cart is plugged into the Writer, the little light on the Writer flashes red. What does this mean? (When I close EZManager, the light stops flashing and glows a steady green.) (When the Writer is writing to the Cart, the light flashes orange, then turns red, that obviously means "Caution! Don't unplug me or remove the Cart!") 3) The scroll message at the bottom of EZManager used to display the latest available version, now it just shows some garbage characters. Should I be concerned? 4) In the 4 Gb area, what are the .inv files? 5) Do I understand this unit's operation?: There are four memory chips in the EZ Cart: 4Gb NAND "EZ-Disk", 128 Mb PSRAM "Hidden", 256Mb "Fast", 32Mb "Boot". When I select a .gba file in EZ-Disk, it is copied to Hidden, which takes a few seconds. (What happens to the contents of Hidden after I turn off the power?) This means only games up to 128 Mbits in size will load from EZ-Disk. When I put a .gba in Fast, it will load immediately. Fast will store one game of the largest known size (256 Mb) All regular saves are stored in the saver folder in EZ-Disk, but only when you turn the system back on. Instant saves (when they work) are also stored in the saver folder. === Much Thanks to anyone taking the time to read [and answer!] any of the above. Cheers!
