Changelog: 0.57
Added FDS emulation (read and write, not sound yet).You need of the FDS bios rom located in one of these folders:
1) the working directory,
2) the folder where is the fds file,
3) "$HOME/.puNES/bios" on linux or "/puNES/bios" on Windows.
The bios file must be called "disksys.rom" and must have a size of 8192 bytes.
Added mapper 37.
Corrected some bugs in the cpu emulation discovered thanks to test roms made by Bisqwit
(http://nesdev.parodius.com/bbs/viewtopic.php?t=8738 and http://nesdev.parodius.com/bbs/viewtopic.php?t=8757).
Fixed a bug that in some circumstances, when attempting to load a save state, it crashed the emulator.
