Looks like the programmer had some sort of weird luck. He probably wanted to
do a SBC #$09, but made a typing error in his code. (Un?) fortunately, this
had the same result than doing a SBC #$09, so the error kept being
undiscovered.
Patching the ROM makes it run perfectly on my hardware, so i will include an
auto patch feature into the BIOS.
