I have a rom that matches the CRC (33912C73) of the updated Kaizo Mario World 2 TAS, however, it desyncs during the yellow switch palace as well.
So, it looks like there are at least two copies of the ROM with different content but the same CRC. (or maybe it was the result of doing hex edit cut & paste with the input?)
Anyway, out of the 5 patches I have for Kaizo Mario World 2, only one patch (CRC32 = 4560ED03) that played pasted the yellow switch palace.
However, it desyncs in the middle of the level that follows.
Can someone please provide a patch that doesn't desync ?
UPDATE: I found a patch that plays until the end of the game.
Here's the ips file:

Apply it to the US version of the SMW ROM.
After applying the patch, the in-game (the one shown in SNES9x) CRC32 = A75B9D22.
I think the Bowser fight is awesome in this hack -- at least it's different than all the SMW hacks I've seen. The last boss is nice too. I wonder how many people can beat the last boss without savestate or tool-assisted.
I would like to thank gocha for posting the SMV files and thank the people who did the TAS for these two hacks!
