Arbee is right. This is at least the fifth investigation into SNES BCD in the last 12 years.

And every time the result is "oops. Bugs!"

byuu, one way to counter the 32 KB limit is "don't store results from the SNES in SRAM, store the emulated results in the ROM". Of course, you'd need to CRC-16 or checksum the results to get a full scan in, and then you'd need to actually check the failed pages later, but it gives you almost 4 MB to play with instead of 32K. It takes you a step further from the hard numbers because you can only get down to "these 8K results add up correctly" or so. But it's a different approach than is usual.
