After close inspection it appears to be an NTSC 60Hz only issue. I played through it from start to finish myself and it never flickered on the top but I played it in PAL 50Hz. After reading your comment I tried it on Regen in 60Hz and there was indeed flickering on the top but it wasn't blue, it was orange. Very unusual that there's artefacting on a game made for NTSC 60Hz, usually it happens on games made in Europe for PAL 50Hz and then sped up to 60Hz.
Still glad this patch kept the original Super Street Fighter II music, the other one from last year had that god-awful music that sounded much, much worse.
