Well it looks like the PowerPak is getting some competition soon from our friends over at NeoFlash, longtime developer of GBA and DS flash carts.
The project is the latest of their so-called Myth projects and sofar only very scarce information is available along with a bit blurry picture.
Like other myth products the FC/NES Myth uses a Neo2/3 (SD) cart for ROM storage, it's going to include real-time save (nice!), Cheat Code support (Game Genie only?).
I'll of course keep you updated when more news arrive from Team NeoFlash.
