Changelog:

added a save/load state system with 6 slots.
F1 = save state
F2 = dec slot
F3 = inc slot
F4 = load state

Changelog:
0.29 (bugfix release)
correct some bugs and redesigned the timeline in the windows version.
In the linux version i dropped the dependency with some libraries (such as the libpng 1.4) and this should make the emulator also run correctly on distributions like Ubuntu.

Changelog: 0.28 in this release I have implemented a "Timeline" bar. In the lower left corner there is now a bar with which you can go "back in time" up to a maximum of 60 seconds. Each tick corresponds to 5 seconds. If you don't want to use the mouse you can also use the keyboar...

Changelog:
0.27
I had forgotten to enable the save of configuration, fixed.

Testing my new MMC1 implementation, I found some problems with "Dusty Diamond's All-Star Softball (U) [!]. nes". After the initial choices the rom hangs in an infinite loop. Tested with other emulators I noticed that there are the same problem. I understood what was the problem and now I k...

In my emu the problem was theat i don't have implemented correct what the wiki explain well: SOROM, SUROM and SXROM CHR bank 0 (internal, $A000-$BFFF) 4bit0 ----- PSSxC ||| | ||| +- Select 4 KB CHR RAM bank at PPU $0000 (ignored in 8 KB mode) |++--- Select 8 KB PRG RAM bank +----- Select ...

I'm rewriting MMC1 emulation and I don't understand well one thing. I tried Genghis Khan which is a SOROM ( http://bootgod.dyndns.org:7777/profile.php?id=919 ) and according to the wiki only the last PRG RAM chip is packed battery, so why if I make a save during the game, reset and try to load data,...
