It looks like my game POLICE PATROL isn't accepting keyinput anymore.
I have loaded multiple versions of the game, even version in a downloadlink that I have marked OK for distribution.

Looks like all versions were corrupt somehow. Altered the code a bit.
Now working.

Re: bugs found on eo
Is opcode 9 wrong in emulation?
I tried same code in EightyOne and on ZX Spin.
LD HL,#FAFF
LD BC,#501
ADD HL,BC
RET Z
In EightyOne the Z-flag is not set when result is #100000 (1 goes to C-flag, but HL becomes 0, thus Z is set)

Re: bugs found on eo
Per design, the Z condition bit is not affected by ADD HL,BC...
Re: bugs found on eo
So it is a bug in ZX Spin.
