Here's a simple patch with bass.exe to make the letter boxing smaller on Street Fighter 2 Turbo. There are two glitches:

1) HDMA parallax is messed up
2) Sometimes the screen flashes blacks when fighting Zangief vs Zangief.

Code:
arch snes.cpu

macro seek(n) {
   origin ({n} & 0x7fffff)
   base {n}
}

seek($80044f)
lda #$06              //scanline of first IRQ previously 20

seek($800524)
lda #$08              //scanline of second IRQ previously 22

This patch is pretty cool. Too bad about the parallax issues at the bottom of the screen. Also, it's kind of weird not having the life bar/clock at the very top of the screen.

Cool patch, is there a way to smaller a bit the original letter boxing while removing remaining bugs (black screens in Zangief battle) ? or they were already on the edge of DMA bandwidth ?
