Update to bsnes v025r12? release.

New WIP is up.

 I fixed PSRAM size, it's now 512kbytes. SRAM was correct before at
32kbytes. I also now save these files to "bsxbios.psr" (PSRAM) and
"bsxbios.srm" (SRAM). I honestly don't know if the PSRAM is supposed
to be battery backed or not. If it's not, it'll be easy enough to
remove. I imagine it is, because that's where you'd store your games
on if you lacked a flash cart. Would be pretty lousy to have it wiped
every time you power cycle.

 I also save the PSRAM+SRAM data only once, just as a real BS-X cart
would work, and it also makes the Ancient Tablets series work with no
file renaming needed. I may add an option later to save these files
separately per-game.

 BS-X support overall is still pitiful. bs-x.txt doc says $03 has to
be set to mirror PSRAM, SNES9x thinks it needs to be clear. Neither
know whether it affects just $60-6f or also $70-77. bs-x.txt doesn't
say to mirror hi/lo on PSRAM based on $02 setting, but SNES9x seems to
try it. LoROM doesn't map well into 64k granularity banks. Still don't
emulate $0c/$0d flash i/o register enable. Base unit is still
completely unsupported, and it's apparently needed for some games. And
I have no intentions of including an internal database of times to
manually hack the clock (even while the system is running!) ala
SNESGT. I'm just going to map the BS-X base unit RTC to the PC clock.
Some stuff like Dragon Slayer Eiyuu Densetsu work fine under regular
mapping, yet don't work with BS-X mapping. No idea why. Still don't
hack-enable headers during load, so that has to be done manually still
(do this if the game doesn't show up in cart menu. Make a backup if
you care.)

 Added SameGame support. Load it with "Load BS-X Slotted Cartridge"
(that's what it is, after all.) Unfortunately, I don't know what the
memory map is supposed to be, so the add-on cart doesn't appear to be
working. Or maybe I just can't figure out how to tell.
 Nach or anyone else, would you mind sharing that info with me? The
code in SNES9x looks identical to what I have, but loading the FEoEZ
512kbyte cart doesn't seem to do anything. Well, at least the game
itself works under this menu option now.

 Fixed config::path.save, and added realpath() for the Linux port, so
./ paths work too. Of course it won't be useful at all if you
"install" bsnes to /usr/bin, but if you keep it in its own folder,
it's helpful.

 Fixed the SRAM mapping bug affecting Fire Emblem 776. Also optimized
the file loading stuff a little more, removing a couple redundant ROM
memcpy's. Still far from perfect.

             If possible, please test this WIP a lot. I'd like to post
a new public release this weekend.
