Better late than never, I have rewritten my "NESColumns" Explorer extension to work with Windows Vista and later.

October 29, 2012

I have returned to NESdev, and with me I have brought the Visual 2C02 and a new CopyNESW build with USB support (from bunnyboy's CopyNES USB version) and 64-bit support (at least for parallel ports).

The iNES Header Editor below, originally uploaded a few weeks ago, has been updated to match changes that had been made to Nintendulator.

A few days ago, I wrote a Windows XP Explorer extension DLL which allows you to view several .NES file properties as extra columns: mapper number, PRG ROM size, and CHR ROM size. NES 2.0 ROMs are supported, and will display both the main mapper number and the submapper using the format "MMMM.SS".
Installation is fairly straightforward - just copy the DLL to a convenient directory and run "regsvr32 nescolumns.dll" to activate it, then browse to each folder containing .NES ROMs and right-click the column header to add new columns. It should be noted that this does not work on Windows Vista or later.

I've heard discussion that neither Nintendulator nor Nestopia support execution of code from the MMC5's 1KB expansion RAM, suggesting that it may be due to optimizations. This is clearly not the case, and to prove it I've hacked my Copper Bars program to run on an MMC5 with part of its code located in ExRAM.
I suspect some confusion may have arisen from the fact that Nintendulator's debugger displays values of $FF within ExRAM even while executing - this is not what the CPU is actually executing, but it is what the debugger shows whenever it is viewing a region of memory it believes to contain I/O registers (which are very likely to result in side effects if they are actually read from).
