There's A Patch For Ikaruga !!!

Or try this :
_ open the image (or 1st_read.bin) with an hex editor
_ look for "0B 42 09 00 01 1F 0C 84"
_ change it by "0B 42 09 00 01 1F 30 E0"

I think it might work if you only do that, but if it doesn't :
_ look for "63 74 20 31 32 20 32 30 30 30 20 31 39 3A 32 30"
_ and change it by "00" until "69 6E 00 53 45 4C 45 43 54 2E 70 76 72 00 00"
==> 255796 bytes !
