Hi there, first post. Most of what I wanted to know I could find, but not answers to these specific questions for the EZ-Flash IV (phat). They may have been answered, but if so, I do not have the required knowledge to fully understand the answers I have read, having no experience yet with slot-2 carts. I intend to pair it with an Acekard 2i. 1. With an image on the flash, can I reboot for saving, load others into the PSRAM, then go back to using the program residing in flash, including saves, without doing any new writing to the flash? 2. Following from the first question, assuming it is a yes, will I need to manually get saves off before writing to PSRAM, which I assume I can do using GBA ExpLoader, or will a boot to the GBA cart take care of that? 3. Since the internal battery may die during its service life, is it a primary?
