Thousand Arms
SRW: Endless Frontier/Endless Frontier Exceed/Project X Zone
Tomato Adventure (Duh)
Popolocrois on PS1 (Now all translated)
Far East of Eden (Only 1 and Zero are available so far)

SaGa on DS remakes
Summon Night: Swordcraft Story (It's even got the fucking yuri like UNDERTALE ...although I hear that it's easily avoidable?)
Contact on DS
Solatorobo
Tingle's Rosy Rupeeland (Not really an RPG but that's what the developers call their weird lovedelic "genre")
Monstania
Robotrek
Zubo (It's a bit simple but the shoe fits)
SMT Devil Children/Demikids
Dragon Quest Monsters
Magi Nation
Robopon (I'm only putting this here because wow, what a shocking embarrassment for RED. At least, the overworld graphics are. The battle graphics are more what you'd expect and the GBA incarnation stops stealing sprites from Pokemon.)
Goemon RPGs on Famicom
Musashi no Boken
JaJaMaru: Ninpō Chō
Rent-a-Hero
Network Adventure Bugsite (Ok. I just picked this one because it has amazing graphics for GBC. Even better than...)

Hamtaro on GBC and GBA
Shadow Brain (Knockoff Megami Tensei)
Doraemon: Giga Zombie no Gyakushuu
Sugoro Quest: The Quest of Dice Heros
