puNES v0.25

"In the future I will use this post to announce new releases and changes.

puNES is an emulator under development that works on Linux32/64 and Windows32. It needs of SDL library to run. Uncompress the zip/tar file in a subdirectory. Run it with the name of the rom as the first argument (or, in Windows, if you don't want use the commandline, drag the rom on the icon of the emu).
P.s. doesn't support zipped rom yet

Current version : 0.25

Changelog:
0.25
Implemented Hard Reset (F11 key) and Soft Reset (F12 key).
Implemented switch from PAL system and NTSC with F8 Key.
Implemented PPU Open Bus and correct some bugs in DMC emulation.
Implemented AxROM, BxROM, GxROM and CPROM mappers.
I finally manage to pass all the Blargg's tests that I've found on the internet (including sprdma_and_dmc_dma.nes and sprdma_and_dmc_dma_512.nes).
0.24
Implemented emulation of mappers MMC2, MMC4, ColorDreams and Camerica.
Correct a little bug and now "Time Lord (U) [!].nes" work without glitches.
0.23
Implemented the save on file for the PRG Ram battery packed.
Rewrite MMC1 emulation and tested with all GoodNES MMC1 roms.
Now work without glitches the MMC3 chinese roms that in the previous version had problems (Aladdin 2 (Unl), Bing Kuang Ji Dan Zi - Flighty Chicken (Ch), Chu Han Zheng Ba - The War Between Chu & Han (Ch) an many others).
0.22
Implemented all illegal opcode.
Rewrite from scratch MMC3 emulation and now really work with every rom that I've tested (for two weeks I've tryed all 5118 MMC3 GoodNES roms including Blargg mmc3 test) except for few bootleg and some chinese roms (why??).
Implemented fix for young indiana jones chronicles (thx James).
0.21
Correct some bugs in the MMC3 (NTSC and PAL) and now
all the roms that I'have tried works well.
0.20
Implemented illegal opcode 0x80 for the "Beauty and the Beast (E) [!].nes" rom
0.19
complete APU emulation.
This is my first attempt with sdl sound and perhaps there may be some bugs. For now, without the implementation of frameskip, the emulator has to work 100% for not having problems with sound skip and crackle.
Changed the structure of the code and now the emu takes less than 100Kb.
Correct many many many bugs.
0.18:
added AxROM (mapper 7) emulation.
0.17:
fixed another bug and now Incredible Crash Dummies run without problems.
0.16:
correct a couple of bugs in the mmc3 emulation.
0.15:
added MMC3 emulation.
0.14:
Correct a a bug in the controller routine (thanks Dwedit).
0.13:
Correct a little bug and now all cpu_interrupts_v2 test roms passed.
0.12:
Implemented reading of $2004 during the rendering.
(thx to Quietust for the info and for the read2004.nes test rom).
0.11:
I worked hard on the CPU and PPU emulation and now many
of test roms worked perfectly (thanks blargg).
Added OpenGL support.
Implemented APU Frame Interrupt (only this for now).
Many bugs are gone.
