Chrono Trigger, Secret of Mana, Link the the Past, Super Metroid, Final Fantasy 4, 5, and 6, Street Fighter 2, the list goes on and on... Back when Square knew how to make good games and didn't go mass market casual appeal.
Things went downhill fast after the death of the 16/32 bit era.
I have my SNES hooked up with a Sony PVM-20M4U professional RGB monitor with a Super Everdrive DSP-1 flash cartridge.
Will be grabbing a SD2SNES cart soon as well, it has a Xilinx FPGA that is powerful enough to reconfigure on the fly to implement all possible special chips (SuperFX, SDD-1, SA-1, DSP etc). Not that it matters since I have nearly all the original special chip games in mint condition with boxes and stuff including SFC Star Ocean.
These carts can play the English patched versions of Tales of Phantasia, Star Ocean, etc on the real console. It's amazing seeing the end of life games in full RGB glory that no emulator, LCD, or upscaler can possibly do justice.
Now if only a NES PPU would be implemented in a FPGA to output native RGB instead of composite. The only way so far is ripping PPUs out of NES arcade boards which don't quite have the right home console palette

The video comes out of a pin on the PPU as a native composite color burst signal so there is no way to hack RGB other than replacing the PPU.
