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 too. The PPU documentation (still WIP) http://docs.google.com/Doc?id=dgkczz7v_8cwncmfcn . News ...

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]

OricutronOricutron (formerly known as Oriculator) is an emulator for the Oric series of computers. It is written in plain C, and uses SDL. It is designed to be portable. It is still in early alpha stages. If you want to discuss Oricutron, or Oric in general, why not join us in #oric on IRCNet? ... [More] ThanksThanks to Stefan Haubenthal for providing a MorphOS build, and agreeing to maintain the MorphOS port. Thanks to Kamel Biskri for the MacOS X universal binary! Thanks to DBug and Twilighte for letting me distribute their Oric software with Oricutron. Latest ReleaseOricutron v0.5 was released on the 24th February 2010. Changes since v0.4:Preliminary VSync hack support (based on guess work). The windows port has an Oric icon. If saving a disk image fails, you are now notified via the info popup. Amiga & MorphOS ports now have a version string. Fixed the broken symbols in the debugger. You can now override default settings with a config file. An example one is provided. Warp speed is properly warpy again ;-) Added tape and AVI capture status icons. Shift register is a little bit better. Oric printer output works again. Long disk image filenames are truncated nicely now (like the tape filenames). Attempted to reduce calls to SDL_LockAudio()/SDL_UnlockAudio() in the emulation loop. Notes about AVI captureThe AVI export uses the MRLE codec. Your favourite player might not support it, but MPlayer plays it, ffmpeg converts it and you can upload it directly to youtube. Note that the MRLE codec shows up some endian-issues on the Amiga OS4 port of MPlayer, so it will sound crappy and have wrong colours until those bugs are fixed :-( [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 that computer. The project consists of HDL for the CPU, written in SystemVerilog, an instruction ... [More] 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]
