I want to make a test ROM that doesn't simply test for SCHIP compatibility (like all the existing ones do?) but classifies your compatibility.

• Get rid of globals
• Create CPU object, and probably others
• Split into multiple files

Not sure if this is a duplicate of #2 or not.

Things to think about:

• Fetch and execute more than one opcode at a time
• Make sure timers tick down at ~60 Hz
• Lock FPS? (See above)

Options:

• Follow PC
• Disassembly
• Jump to
• Breakpoint

• Break on unknown opcode
• Breakpoints
• Break on V access/change
• Break on memory write/read

Native File Dialog?

Don't draw everything to the screen each frame, that's probably pretty slow (see #2). Instead, draw to a canvas whenever the screen data changes, and draw the canvas to the screen each frame.

This thing runs really slowly.

Add Super-CHIP instructions

According to Wikipedia, FX1E should set VF to 1 if it results in I overflowing from FFF (not FFFF?)

Create separate display modules that alter screen resolution and effects.
