* and you can put anything you can pass on the command line into a
* configuration file ~/.uaerc. Please read the documentation for more
* information.

/*
* This variable was introduced because a program could do a Bcc from
* whithin chip memory to a location whitin expansion memory. With a
* pointer variable the program counter would point to the wrong location.
* With this variable unset the program counter is always correct, but
* programs will run slower (about 4%).
* Usually, you'll want to have this defined.

/*
* The blitter emulator contains a few optimizations. You can choose one out
* five methods.
* 0: Old uae-0.1 style blitter. Slow.
* 2: This is the most reliable one.
* 3: This tries to do 32 bit accesses when possible. It will not work on
* most RISC chips (expect to see bus errors)
* 4: Like 2, but the blitter finishes instantly. May lead to
* incompatibilities, since some programs depend on the blitter delay.
* 5: Like 3, but the blitter finishes instantly.
* I recommend methods 4 and 5 only for Workbench based applications, although
* well-written games should have no problems with these.

* CPU level: 0 = 68000, 1 = 68010, 2 = 68020/68881
* If configured for 68020, the emulator will be a little slower.
* Proper 68020 support is new in this version, but it ought to be reasonably
* stable.

* Define this when you are compiling UAE for the first time. If it works, you

/*
* When these two are enabled, a subset of the ECS features is emulated.
* Actually, it's only the chip identification and big blits. This may be
* enough to persuade some ECS programs to run.
* DON'T enable SuperHires or Productivity modes. They are not emulated,
* and will look very messy. NTSC doesn't work either.

* If you don't have any sound hardware, or if you don't want to use it, then
* this option may make the emulator a little faster. I don't really know
* whether it's worthwhile, so if you have any results with this one, tell
* me about it.
#define DONT_WANT_SOUND

/*
* If you don't care about games, this may make the CPU emulator run faster,
* but it will take longer to complete one frame. For UltraSparc owners this
* may be a good way to lower the key repeat rate.

/*
* When USE_COMPILER is defined, a m68k->i386 instruction compiler will be
* used. This is experimental. It has only been tested on a Linux/i386 ELF
* machine, although it might work on other i386 Unices.
* This is supposed to speed up application programs. It will not work very
* well for hardware bangers like games and demos, in fact it will be much
* slower. It can also be slower for some applications and/or benchmarks.
* It needs a lot of tuning. Please let me know your results with this.
* The second define, RELY_ON_LOADSEG_DETECTION, decides how the compiler
* tries to detect self-modifying code. If it is not set, the first bytes
* of every compiled routine are used as checksum before executing the
* routine. If it is set, the UAE filesystem will perform some checks to
* detect whether an executable is being loaded. This is less reliable
* (it won't work if you don't use the harddisk emulation, so don't try to
* use floppies or even the RAM disk), but much faster.

* Some STUPID programs access a longword at an odd address and expect to
* end up at the routine given in the vector for exception 3.
* (For example, Katakis does this). And yes, I know it's legal, but it's dumb
* anyway.
* If you leave this commented in, memory accesses will be faster,
* but some programs may fail for an obscure reason.
