Potential Issue: CPU is getting stuck around PC 0x0064-0x0068 because the PPU is not writing to memory after v-blank period

With PR #38, the CPU now moves past PC 0x0068. Still need to follow the next CPU steps to make sure it doesn't hang elsewhere.

Screen is still blank, so problems for sure still exist.

Getting stuck between 0x007A and 0x0080

With #42, rom data is loaded, and the PC progresses past 0x00FE.

The time it takes to read the BIOS is still very slow (measured in minutes), and the LCD is still not displaying anything.
