Py65 provides tools for simulating hardware based on 6502-like microprocessors.

This is and old project of mine, make something like MESS (or MAME) but in the pure Python.

JnesBR Another-Yet-NES-Emulator-DebuggerAnother project about coding a NES (Famicom) emulator. This project have been developed using Java as language. A debug system is one of goals from this project ... [More] too. The PPU documentation (still WIP) http://docs.google.com/Doc?id=dgkczz7v_8cwncmfcn .

Sprite DMA and normal sprite handling. General fixes (absolute indexed store.). Better colors for name table/attribute table. 04-09-2009 15:03 The palette viewer was implemented. The multi pattern table was implemented. (reading pattern tables from rom too!) The name table was implemented. 04-05-2009 21:41 All legal opcodes and opcoes were implemented. PPU emulations starts with force. Palette Windows already shows the first drafts. 04-04-2009 14:34 Almost all opcodes and some illegal opcoes were implemented. 03-28-2009 16:12 Addition of special comment at IO mapped memory (ppu, apu, joystick). 03-23-2009 10:36 Refactoring and reviewing all instructions classes. 03-07-2009 15:34 Unique way to handle memory. Dec and inx instructions, a lot of fix for comparison instruction. Run n steps implemented on debug system. 02-24-2009 11:25 More refactorings. All branches relatives implemented. Ppu status and more debugger gui for ppu state view. Pallete location on memory map. 02-16-2009 22:56 Gui icons. Start ppu debug windows. Ppu registers now change the state of ppu. 02-07-2009 15:01 Pattern Table viewer & Video Memory Viewer. 01-30-2009 23:20 Simpler and functional debugger. Memory viewer now is working. More instructions implemented (btw the addressing modes too). General fixes, around wraparound, endianess, signed byte ... 01-25-2009 21:30 Rom reader , shows the header of iNes rom. Memory viewer is visible and seems to works (at least with no mapper games). Some few (around three) insctructions was implemented. The base architecture is already done. The initial debug system was started. [Less]

Twoapple: An Apple II+/IIe emulator for LinuxNews(version 0.6.50)IIe emulation is working. (version 0.5.43)Disk II emulation is working. (version 0.3.34)Speaker emulation is working. (version ... [More] 0.2.31)6502, video, and keyboard emulation is working. See ReadMe for details. [Less]

An application (desktop) server which provides services (ntp, ftp, svn, cvs, etc) to a vintage computer via the serial port and/or ethernet port. Initially, the primary focus of the client computer ... [More] is the Apple II platform. Other 6502 computers can be adapted to run relatively easy. Clients are able to utilize the application server services via a RPC mechanism. [Less]

In 1981 Commodore issued a series of games for the newly-released VIC-20 computer. Duane Later wrote Blue Meanies From Outer Space, a Space Invaders derivative, in BASIC. There have been several ... [More] remakes of the game for other platforms in recent years - this is not one of them. Blue Meanies Revenge is a sequel to the original game, again for the VIC-20 (or VICE emulator) but written in 6502 Assembly Language, and featuring new gameplay and extended functionality. The basic framework of the original game is retained, but various additional elements separate this sequel from it. [Less]

This project is to recreate the 6502 microprocessor that will be pin and instruction set compatible with the MOS Technology 6502 in the Apple II series of computer, and will be drop in compatible with ... [More] that computer. The project consists of HDL for the CPU, written in SystemVerilog, an instruction level emulator for the CPU, a full regression and unit test suite, a random code tester and demonstration and example code. Eventually, the HDL design will be implemented in hardware. [Less]
