Hi all,
I've tested tron2001 for falcon.
This game crashes always at the same instruction : the sf $f0000
> d
$0004e8a4 : 51f9 00f0 0000 sf $f00000
$0004e8aa : 303c 3111 move.w #$3111,d0
$0004e8ae : 4e7b 0002 movec d0,cacr
$0004e8b2 : 41f8 8200 lea $ffff8200.w,a0
$0004e8b6 : 43fa 0684 lea $4ef3c(pc),a1
$0004e8ba : 12e8 0060 move.b $60(a0),(a1)+
$0004e8be : 12e8 0065 move.b $65(a0),(a1)+
According to a hardware registers file I have on my hardrive, it
says this area is a reserved I/O space, but should it bomb on falcon ?
