I think are some good PD games (if you refer to Dingoo PD games).
SameGoo is solid if you like SameGame (well I could be biased on this one
)
Spout is really cool I think. I have not tried XRickOO or ManicMiner, but those are remakes of classic games, and seems to be well recieved by the community. Haven't played Mushroom Roulette that much.
Although I will remove Minesweeper, because it seems like you can only play with a small field with max 3 mines, which makes it a bit dull.
New games I've found:
* Formula1 (a clone of a Game&Watch game)
* Hell Striker II (From Dingoo, also known as World Road)
* Landlord (from Dingoo)
* Nosebreaker (from Dingoo)
* Overlord Fighter (in chinese but you really don't need to know chinese to play)
EDIT: This is really called "Yi-chi King Fighter"* Platinum Sudoku
* PoPo Bash (in chinese but very playable without understanding it, a Puzzle Bobble clone)
* Rubido
Edit: Oh and by suggestion from omgmog, readmes will be placed in TXT/README so that they are easily read with the Ebook function.
