a/a.bps                 -> ask for in rom (opt), ask for out rom (opt), launch emu (opt)
a/a.bps b/b.smc         -> -a a/a.bps b/b.smc a/a.smc
a/a.smc b/b.bps         -> -a b/b.bps a/a.smc b/b.smc

a/a.smc                 -> error
a/a.smc b/b.smc         -> error
a/a.smc b/b.smc c/c.bps -> -c a/a.smc b/b.smc c/c.bps
multiple patches -> error
anything else -> error

allow -a and -c for overriding this
allow applying IPS, UPS and BPS, but only create BPS in GUI; CLI supports everything (maybe an advanced mode that exposes everything?)
only use the delta creator; moremem is worthless, remove it

also need this new feature:
--romhead=512 - discard 512 leading bytes in the ROM before sending to patcher
--patchhead=512 - prepend 512 leading 00s before patching, discard afterwards
--outhead=512 - prepend 512 leading 00s after patching
if both romhead and patchhead are nonzero, replace the leading min(romhead,patchhead) 00s with data from the rom; same for outhead
if patchhead or romhead isn't set, it's 0
if outhead is not set, it's romhead
if none are set, romsize modulo 32768 is 512, and file extension is sfc or smc, set rom/outhead to 512 and patchhead to 0
if patching fails, retry with all headers 0 and throw a warning
