PSX:
Shadow Tower. From Software King's Field type game and one of my favorites of all time. I was pleasantly surprised when I finally managed to set a PSX game to boot on my X7 handheld, and it actually runs pretty well too. Unfortunately, the X7 only has 2 shoulder buttons, not 4, and L2+R2 are used to look/aim up/down in this title, so, I can't even hit the first enemies on the ground (slimes)! The game lets you remap buttons, but, not 2 functions to the same one, so, the situation is unfixable. Such a shame. It's mystifying that they'd even support PS1 emulation on a handheld without sufficient buttons. At the very least, they should have let you use another button as a shift key to change L1/R1 into L2/R2...
