OK it's done now I updated ROMs and sources of my window demo updated with Blargg's synchronization: http://jonathan.microclub.ch/window/
The "old" versions use simple sprite #0 hit, but the NTSC version glitches on real HW (altough it looked fine in both Nintendulator and Nestopia).
The source is a big pile of junk btw but it's there. Tested & glitchless on both NTSC and PAL, Nestopia seems pretty accurate at emulating both.
Although, even with Blargg's synchronization, I had to place 2 blank tiles before the end of the screen and 1 blank tile after it to get this glitch-less. Maybe I did something wrong ? With NTSC only 1 blank tile before the end was necessary, but I wanted it to be dual NTSC/PAL anyways.
