Chip-8 has no ROM, nor memory management.
- It's much easier to just use contiguous memory.
- Then we can return references to slices of that memory
- ~3x speed increase
Screen exists now, uses 24-bit framebuffer
- We have a 1-bit framebuffer
- I chose colors that look good to me
Controller exists as well, has 16 buttons
- Mapped "0 123 456 789 ab cdef" to (QWERTY) "X 123 QWE ASD zC 4RFV"
- Other chip-8 interpreters may use a different layout
- This is good enough for now.
- F1-F9 map to control functions
- F1, F2: Dump CPU registers/screen contents
- F3, F4: Toggle disassembly/pause
- F5: Single-step the CPU, pausing after
- F6, F7: Set/Unset breakpoint
- F8, F9: Soft/Hard Reset CPU
