For some reason I don't get any sprites in Road Rash, but Road Rash 2 works fine and the sprites now lean in the correct direction.
Here's what I've changed currently in Cyclone
+ Fixed btst opcode, The bit to test should shifted a max of 31 or 8 depending on if a register or memory location is being tested.
+ Fixed abcd,sbcd. They now decimal correct correctly
+ Fixed addx,subx, they should not set Zflag if result is zero.
They only clear the Zflag is the result is not negative.
+ Fixed rol opcodes, they were not setting flags correctly
+ Fixed asl/asr/rol/ror opcodes, X flag should not be updated when shift count is 0
When I've finished I'll send you the source.
