    @tptquantum The speed is still the main problem here. The SNES's CPU is about 3 MHz. That's 3 million operations per second. Powder Toy processors are 60 Hz. Even if you use tpt.setfpscap(2), it probably isn't going to go above 500 Hz. To top that, the SNES had special hardware for graphics processing (read: GPU). So it's not going to be as simple as converting the screen to 16-bit.

    you should make a 16bit screen for the R16K1S60, snes emulator in TPT? +1

    @The8BitPotato Unfortunately, the R16K1S60 may be too slow to do anything interesting with this screen. Just going through 20 columns would require 20 frames, which is already 1/3 of a second. Also, this screen is 20-bit, while the R1 is 16-bit. @mjpowder Is there something significant about the date that I'm missing?
