Description

Pokémon Snap (VC N64) - NAKE

The "You will need a Classic Controller." screen can take several minutes to finish. It should only take a few seconds.

(2015-06-21 12:32:36) phire: So, I possibly know why pokemon snap is taking so long to start the first time
(2015-06-21 12:34:10) phire: it's writing a 144kb file, 64 bytes at a time
(2015-06-21 12:34:45) phire: each call to IPC_HLE::Write opens the file, writes the 20 bytes and then closes the file
(2015-06-21 12:35:00) phire: er, 0x20 bytes
(2015-06-21 12:35:10) phire: which is actually only 32bytes

This only happens on the initial time Pokémon snap is launched, To reproduce you may need to delete the save file.

This behaviour was introduced by revision 53d2d9718fe3

Unfortunately the commit message doesn't say why the change was made, I assume Poképark Wii is doing something weird with the filesystem, possibly with multiple copies of the same file open.

Perhaps Matt_P can enlighten us.
