Emulating on the JVM

" summary

Builds a working CHIP-8 emulator on the JVM using JavaFX, implementing the chip’s 35 instructions, 4 KB memory map, 64×32 monochrome display and 60 Hz timers. Solves Java’s signed-byte problem with unsigned byte masking and manual range checks, assembles two-byte instructions with fetchOpcode combining two bytes, wires keyboard and rudimentary sound (sound not fixed yet), and demos games like Invaders where graphics flicker as expected but the emulation runs.
