-also need this new feature:
---romhead=512 - discard 512 leading bytes in the ROM before sending to patcher
+-a --apply can handle IPS, UPS or BPS
+-c --create can handle IPS or BPS (delta creator only, remove moremem)
+-m --manifest -i --info - exists (if there's a manifest but -m is not present, print that)
+-s --silent - don't print anything on success, also silence BPS create progress (but do print on failure)
+-h -? --help -v --version - exists
+--ips --bps - removed, use the correct extensions
+
+replace --exact:
+--inhead=512 - discard 512 leading bytes in the infile 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
+--head=512 - set both inhead and outhead
+all three default to 0
+if both inhead and patchhead are nonzero, replace the leading min(inhead,patchhead) 00s with data from infile; same for outhead
+if none are set, insize modulo 32768 is 512, and file extension is sfc or smc, set in/outhead to 512 and patchhead to 0
+if the above happened and patching fails, retry with all headers 0; if success, throw a warning, else return error for unheadered file
+
+database:
+on successful BPS application, add without asking, even if that size/sum is already known (but don't add the same file twice, of course)
+if file disappears or its checksum changes, delete and try another, if any
+on failed application, or successful IPS or UPS application, do nothing
+~/.config/flips.cfg
+#Floating IPS configuration
+#Version 2.00
+database crc32=b19ed489 size=524288 path=/home/alcaro/smw.sfc

+assoc-target=ask # or auto or auto-exec
+create-show-all=true # affects whether Create Patch (GUI) defaults to all files, or only common ROMs
+
+GUI is same as Flips 1.31, except
+- no IPS creation
+- publish size/checksum of infile info in failure message
+- no manifests
+- replace settings window with list of db files (including add/delete buttons), and assoc-target config (don't allow disabling db)
+- rewrite using Arlib
+which means these limits compared to CLI:
+- can't create IPS
+- no manifests
+
+patch wizard:
+first, get infile from DB or user
+then, depending on config.assoc, one of:
+ ask user for outfile path (default, default to default path)
+ write outfile to default path
+ write outfile to default path; suppress success message (but not warnings), instead launch outfile using default OS associations
+  don't touch stdin/stdout
+   on Windows, launcher is GUI and doesn't care; ignore stdio
+   on Linux from CLI, act as if running launcher directly; ignore stdio
+   on Linux from GUI, stdio are devnull and can safely be ignored
+   on every platform is 'do nothing' a valid choice
+  don't clean up outfile, let user do that; user is looking at default path, he'll find it
