Hi all, been a long time since I've used my M3i Zero in my DS Lite so I wasn't even sure what versions of the various files I was running. I tried flashing to the latest f-core and updating the system folder but the card wouldn't boot. I decided to start fresh since there were many old files on my sd card. I reformatted my microSD card with the Panasonic formatted, put the system folder from 2.0.0-2U/E/J (25408-SYSTEM_ENG is the file name) on the card, and flashed the f-core (F_CORE_v2.0.2). The card booted up fine using the stock M3 firmware, I was even able to boot to my old EZ slot 2 card. I'm still using a DS Lite so it may not be completely necessary to be current, but for sake of game compatibly I thought this would be the way to go. What firmware should I use, and how to I "install" it? Just drag the files into the system directory? It has been a while and I'm pretty rusty at this. It seems that from reading some forum posts, updates to the M3 products are few and far between which is sad. It also looks like Sakura hasn't been updated since February. Should I use an alternate firmware? I'm not too picky about firmware but I do use the cheat options so I'd like that supported. Any recommendations? Thanks for any help, trying to get back into the swing of things and am confusing myself more and more as I continue to read posts.
