Very, very nice, many of my bugs got stomped
X2USB.dll conflict with NPK is no longer as well.
I have been able to get it working with GBA flashed to the neomax, but for whatever reason NDS flashed to the neomax or SD dont seem to work (nice to see both nds and gba flashing to the flashcart now too) - although it does something with them... saver produces an error message for GBA and NDS when the cart is formatted to use SD as the save backup location. Used bubble bobble NDS and gauntlet gba as the testers just now.
edit:/ This is just awesome and I cant wait till everything is working right in it (well, I can wait but I am excited to see this today). I held start down on my FlashMe DS (since it tries to boot to nds mode with the header for this apps boot menu) and ran it as gba mode, and I have full access to the GBA files I put on there, in GBA mode. A dual boot menu for both GBA and NDS. With Multi-rom support! Sweet 
edit2:/forgot to mention, version info all still states 1.0 for those of you that upgrade
I have NEMOAX KIT 16G now:
