Tim Allen 9560959fef Don't bother with Cirrus for anything but FreeBSD builds. 
Since we have different hosts for different builds, let's try linking to them
directly. I vaguely recall this stopped working at some point, but we'll try
again.

Tim Allen 2b7bc3b08e Build bsnes with GTK+3 on Ubuntu and FreeBSD. 
The latest version of Ubuntu no longer provides the GTK+2 libs that bsnes
requires.

Adrian Siekierka dab534b658 wdc65816: fix PLB wrapping in emulation mode (#1277) 
>Regarding PLB, it looks like it reads from $200 and snes9x, mesen,
bsnes, and the official CPU manual all got it wrong.

Tim Allen 7ec3077079 Revert "nall: Add needed #include <stdexcept>" 
This reverts commit e658f50da2.

bsnes' compatibility with GCC 13 was already fixed in a different way in
5cefce5c08.

Tim Allen e658f50da2 nall: Add needed #include <stdexcept> 
Taken from ares commit 6a7898396a14eef257e63cd002fb26ffbf6e2581

Apparently this is needed by GCC 13.

Tim Allen 3ca0504e67 Extend the Super Famicom LOROM-RAM#A memory map. 
Although Nintendo made many different cartridge circuit boards with different
memory mappings, ROMs do not indicate which specific board they are intended
to work with. Super Famicom emulators traditionally group mutually-compatible
mappings together and use heuristics to guess which family of mappings the
game expects.

There's one family of mappings that maps ROM data to the top half ($8000-$FFFF)
of memory banks in the Super Famicom address space. For historical reasons,
this family is called "LoROM" and has three main variants:

1. ROM only, mapped to the top half of every possible bank.
   The boards database calls this "LOROM".
2. ROM mapped to the top half of every possible bank,
   RAM mapped to the bottom half of banks 70-7d,f0-ff.
   The boards database calls this "LOROM-RAM"
3. ROM mapped to the top half of low-numbered banks,
   RAM mapped to both halves of banks 70-7d,f0-ff.
   The boards database calls this "LOROM-RAM#A"

The largest official game that used variant 3 was 1MiB, so a common heuristic
is "if the ROM is 2MiB or less, use variant 3, otherwise use variant 2".
2MiB is used as the threshold instead of 1MiB, perhaps so somebody can expand a
commercial ROM that uses variant 3 without having to rework it to suit a
different mapping.

Since v107 or so, higan (and by extension, bsnes) has implemented variant 3 by
mapping ROM to banks 00-3f,80-bf, which exactly fits a 2MiB ROM. However,
other emulators like Mesen, snes9x and higan v106 implement it by mapping ROM
to banks 00-6f,80-ef, all the space that is left after the RAM is mapped.

This doesn't affect any verified games in the `Super Famicom.bml` database,
since those have specific, accurate memory maps. It also won't affect
well-written games that only read from memory addresses they have populated.
However, homebrew games and ROM hacks that have never existed on a real circuit
board depend on these heuristics across all devices that read Super Famicom
ROMs, including software emulators, flash-carts, and FPGA implementations, so
bsnes should match what other emulators do.

Fixes #278.
