The BAD_DUMP rom in spaceftr (Space Fortress (Zaccaria)) is fortresp7.7p.
This rom has two different bytes as the rom starcas1, stellcas and starcase uses.
They uses all the same rom (crc = d8f58d9a). If you use this rom for spaceftr,
the spaceship can turn to the right direction again (!).
If you compare the DASM from spaceftr with starcas1, stellcas or starcase you
see that the two different bytes are the result of a bad dump.
Space Fortress uses the same rom as starcas1, stellcas and starcase.

yes, it looks like bitrot. 1 bit is different in each case.

Indeed, only 2 bytes difference between fortresp7.7p (bad dump) and starcast.p7. Looking at the disassembly, these bytes clearly results in bogus code.

Is anyone against it if we just assume fortresp7.7p rom is the same as its siblings? + include a /* note in source */ of course
