DUMA library

DUMA (Detect Unintended Memory Access) is a multi-platform memory debugging library. It can detect memory leaks and buffer overruns (or underruns) in a malloc() / new memory buffer. DUMA is a fork of Bruce Perens' Electric Fence library.

jchip8br

The Chip8 is the target software project for those which want to start code an emulator. This project is another example of this "machine". The language choosed was Java and to render stuffs was used Java2D, there is a chance to make one render engine using jogl. (in the future). An simply ... [More] debugger system is offered too. A two notation disassembler (David Winter & Michael Toren) is inside too. ---- Thanks for all info on the Internet (mainly to these authors Winter and Toren) and thanks very very very much to runawayprisoner (from forums.ngemu.com) thus like to emutalk chip8 thread. ---- Emutalk Chip8 Thread http://www.emutalk.net/showthread.php?t=19894&page=88 Ngemu Chip8 Thread http://forums.ngemu.com/web-development-programming/114578-chip8-thread-new-post.html ---- Some screenshots [Less]

jnesbr

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 ... [More] You can check it out the earlier screenshots http://code.google.com/p/jnesbr/wiki/screenshots The ideas behind the JNesBR CuriosityWith the beauty title OO - The other end of the spectrum you can read some opinions at address http://forums.thedailywtf.com/forums/p/11143/193235.aspx and they're think my project could be claimed as one WTF.

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]

mpatrol

mpatrol is a link library that attempts to diagnose run-time errors that are caused by the wrong use of dynamically allocated memory, including writing to free memory and memory leaks.
