30000Pigeons, if you were wanting to use these – the label files are there and ready to use.
If you are trying to convert your own images to .label files for the HB+, you can download the HyperFlasher software for the original HyperFlash32 flash carts. That software can convert image files into .label files, they will be shown in the software as grayscale but the HyperBoy+ uses the same format and will display the .label file in Black, White, Yellow, and Red instead of Black, White, Light Gray, and Dark Gray like the original HyperFlash32 carts do. You can find the HyperFlasher software on this site or (I think) on RetroOnyx’s website.
I can’t remember where I found the big key in the tower, but I can tell you that the dragon forms stay with you from the time you get them and you should be able to freely swap between them as necessary. Pressing right or left on the right dpad should bring up the dragon form menu repeatedly so you can swap around.
I think it may be time for you to upgrade your flash cart!
It’s the same five blocks each time and they line up the same each time, they just come into the screen at random starting points and tumble randomly to get their respective places in the opening line up.
Does it give you a random word every time? With no save functionality, it won’t just repeat the same series of words the next time I boot the game up, will it?
