Overview
Project Manhattan is a cutting-edge emulator that combines the power of the MOS 6510 CPU with a custom GPU, all implemented as a system-on-chip emulation. Written entirely in FreeBASIC, this project aims to bridge the gap between classic computing and modern applications.
Key Features
- Accurate MOS 6510 CPU emulation
- Custom GPU implementation with GLSL support
- Hybrid architecture for both gaming and business applications
- Ring-0 level access for system programming
- Integrated assembler for low-level optimization
- Compatibility with C64 software library
- x86 translation layer for enhanced performance
Code Sample
' MOS 6510 CPU Emulation Core
Type CPU6510
A As Byte ' Accumulator
X As Byte ' X Index Register
Y As Byte ' Y Index Register
SP As Byte ' Stack Pointer
PC As UShort ' Program Counter
P As Byte ' Processor Status
End Type
Dim Shared As CPU6510 cpu
Sub EmulateOpcode(opcode As Byte)
Select Case opcode
Case &h69 ' ADC Immediate
cpu.A += ReadMemory(cpu.PC)
cpu.PC += 1
Case &h8D ' STA Absolute
WriteMemory(ReadMemory(cpu.PC) Or (ReadMemory(cpu.PC + 1) Shl 8), cpu.A)
cpu.PC += 2
' ... more opcodes ...
End Select
End Sub
' Main Emulation Loop
