Hello everyone, I'm more of a casual visitor on GBATemp, and I have read a lot of topics about this but I can't find the solution. About one or two months ago I bought a EZ-Flash V 3-in-1 from ShopTemp (together with a nice Acekard2i). I recently (7 days) received it in my house (yes, it took a LOT of time to arrive). The acekard works wonderfully, but the 3-in-1 behavior is really weird. I'm using AkAIO 1.7.1. First, I started using really common games, like F-Zero Maximum Velocity (pre-save-type-patched with EZ4Client). The game runs perfectly out of AkAIO. I played perfectly a whole cup, checked out rankings and restarted. AkAIO asked me to save the GBA SAV, I accept. Then, I tried with Super Mario Bros Advance (also patched). The game runs off perfectly, I play for a while, check that it actually saved and then restart the DS by storing the SAV. However, when I run again F-Zero MV, my save game is lost! I restarted without creating a new game and ran SMBA again, the save game stays there. But if I save a F-Zero game again, SMBA loses it's save game. At first I thought it was a discharged battery (as several topic pointd out to), so I opened it up and tested it: only 1V. So, I proceeded to follow the instructions in other forum thread (actually I downloaded the PDF version from FileTrip). I changed the battery: perfect 3V. Retried the same procedure, to no avail. Second, I looked up and found out that I could use GBAExploader. So, I tried using it, but after loading a game, the NDS stays with white screens, if it loads at all. Sometimes, it just locks up on the loading screen. Third, I searched again and I found out I could use NOR to store a GBA game and run it off the NDS main menu. So using AkAIO, I tried to store the ROM in NOR. The process starts, but when filling the first or two pixels out the progress bar, it gets stuck. The AkAIO clock colon indicator still blinks nevertheless, so the DS is not locked up (albeit all other functions (brightness) are locked). So, using GBAExpLoader, I press R and start NOR mode. The process starts and gets stuck in 1 or 2%. So, I ruled out NOR. Fourth, I tried the rumble pack, works perfectly. I tried the memory expansion with NDS Browser, and works perfectly. So, in the middle of this desperation, I started testing every GBA testing program I could find in FileTrip: - GBALdr: Gets stuck at 0% when writing NOR. - NDS Backup Tool 3-in-1+: Doesn't recognizes the GBA expansion. - Cory1492 Test: This occurs: So then I took this picture of the PCB, wondering if something is wrong (gives out EZ5C11): (which together with Cory1492 test, and the proof from GBAExploader, gives me that the 3-in-1 is actually version 1) Do you know what can I do in this particular case (besides the "only play one GBA game at a time" solution, which seems to work)? Thank you a lot for your time. P.S. It's physically impossible for me to resend this item back to ShopTemp for warranty (well, if changing that battery didn't blow up my warranty already). That only would cost me about twice of what I paid for both items. P.S.2. I took those pictures right now, not in the moment I did what I said.
