    Code to make Nagano Olympics (Japan) compatible

    To run NH5J in Nemu set 800016D4 to always return: 810016D4 1000. Nagano Olympics implemented a strange anti-flashcart strategy. In the Japanese version (NH5J) a test against the ROM's first 256 bytes occurs at 800016BC. This test causes a bit of a problem for some emulators, such as the...

    DMULTU error

    Nemu says DMULTU: 00000000000031E1 * FFFFFFFFFFFFFF1D = 000031E0FFD3C57D but should equal: FFFFFFFFFFD3C57D In other words, Nemu handles DMULTU the same as MULTU! Turns out the reason GoldenEye suffers those crazy blackout issues is due to an error in the way DMULTU is handled. It's being...

    Why Desha de Go doesn't like to be emulated

    Worked out why most emulators can't play Densha de Go. There's an error in the game itself! On console, when you read ROM using the PI, it can't just read a single byte of data. Instead, it will read something like 16 of them. That's why they always pad memory and copy from an offset and...
