Hello, I just bought a EZ Flash IV(EZ4) from realhotstuff and after setting it up, I really like the device. I'm want to make sure I understand this thing as much as I can, so any help would be greatly appreciated. OK, here is what I was wondering about: -The SRAM is powered by the battery inside the flash cart, and the SRAM is used for storing saves when the power on the GBA/DS is turned off. So if the battery is dead, turning the GBA/DS off will cause the most recent save to be wiped. However, if a game is saved, and then reset back to the flash cart menu, it will save just fine, even if the battery is dead. This works because the flash cart will write the save to the miniSD as soon as you reset. So the battery isn't "necessary" as long as the in-game reset works. Is this correct? -After reading online is seems that the very first batch of EZ4s came with a rechargeable battery, but later models came with a non-rechargeable battery. I'm guessing they did this to lower costs. If the battery had an orange outline, that meant it was rechargeable. If the battery had a yellow outline, that meant it was non-rechargeable. I'm guessing that if someone wanted to they could unsolder a non-rechargeable battery and solder in a rechargeable battery pack. The rechargeable battery would last longer, even if it would eventually lose its ability to hold a charge. Is this correct? -I have the latest client for the EZ4. I also have the latest kernel, which is 1.72. However, I have read that there is a kernel called 1.72 RESET. I do not know what the difference is between 1.72 and 1.72 RESET. Can anyone tell me what is different between the two kernels? I intend to use the EZ4 only for GBA games, and all the games I have on it work great, along with the reset working fine for all the games. I really like this cart and would like to prolong its life as long as I can, since GBA flash carts are rare and probably won't be available for purchase in the future. Any help on the above subjects would help me out a lot. Thank you.
