This seems to be in a permanent loop? yet has a cheat assicated with it? what is the cheat for as it has no note on it.

This build recalculates the CRC 1 and CRC 2 of any rom that has been loaded except for the 64DD IPL rom.
That means this game will have it's CRC 1 and 2 corrected and will be allowed to load.

This build also has the change suggested by nekokabu to allow the 64DD IPL rom to work.
The modification will show the CIC chip as CIC-NUS-6109.

Almost forgot to mention.
The release build will display a prompt informing you the cart's CRC 1 and CRC 2 are invalid if the calculated CRCs are different.
This display is not in the 1.6.1 build as I believe it would be annoying for the user.

Edit #2
This build should now use the old CRC1 and CRC2 for the purpose of loading and saving the rom options while the game is running.

There was a problem in the build I uploaded earlier.
It would crash when loading any rom under 8mbits because of the CRC calculation I added.
This new version will handle the CRC calculation for any rom, including the ones under 1mbit.

[nekokabu]

loading state has Warning Dialog. bugs CRC recalculation?

The save state problem was caused by an extraneous copy that was made to compare the save state's CRC1 and CRC2 to the loaded rom's.
I thought I had removed all but one of those copies but I missed this one.

The CRC recalculation shouldn't have any problems in these later builds.
It was redesigned to fail sanely by not computing the CRCs if the CIC chip is not recognized or to simply read in 0s if the address is out of the rom's address range.
