PCSX2 17.11.04
GSDX9 19.11.04
EE compiler on
It appears to be yet another refurbished vintage game:
www.gamefaqs.com/search/index.html?game=Strikers+1945&x=0&y=0


With this game PCSX2 (or GSDX9?) has problems with GS_CSR, therefore use following patch:

gametitle=Strikers 1945 NTSC-J
//Skip FMV
patch=0,EE,001ad550,word,24020001
//brute force fix GS_CSR
patch=0,EE,0019d89c,word,24020000


This is the fishy piece of code:

OK,
i made a little chronology:
beta 30.03. - 16.06. = loads some stuff, but no pix
beta 14.07. - 16.09. = run fine
beta 30.09. - 10.11. = freeze at FC:112 before 1st picture
beta 17.11. works with patch above

i made a snapshot with GSsoft in arcade mode...

I tried it with the latest beta I compiled, and it runs perfectly without patches in gsdx9 and gssoft 0.8.
