This is a port of the SuperNES-emulator Snes9x, that is available for a vast
variation of platforms.
DO NOT DOWNLOAD THIS IF YOU ONLY HAVE AN AGA-SYSTEM! It doesn't currently
support AGA, I've been
working very much on the gfxcard-support, and will add AGA-support soon.
PowerUP and m68k port will follow shortly.
And no, there is no sound (yet). I've done this port from scratch, and
prioritized a decent gfxcard-
support at first. After this, I'll try my hardest to get sound working without
slowing the
emulation down.
There are a few switches that I've added that aren't in the original version:
-hicolor Selects 16-bit hicolor rendering instead of 8-bit CLUT rendering
-transparency Enables transparency in 16-bit hicolor
-modeselect Brings up a screenmode-requester (use only if you can't get a
proper mode)
-directhack This disables the locking of the bitmap, use if you know that
the display won't
be swapped into fastmem. (This will remove the context-switches
needed for the
locking)
This version of Snes9x is compiled with EGCS 1.1.2 (91.66), with almost no
modifications to the
original source(except for a few ones that reduced the executable-size with over
400kB :D). I've
also used PhxAss and vlink to assemble and produce elf-objects of the m68k-code,
so it could be
linked properly to the ppc-code in a proper way, producing a mixed-binary. (Both
by Frank Wille,
frank phoenix.owl.de)
The input is driven entirely on the m68k, and there is no communication
whatsoever between the
ppc and 68k for input, and with -directhack there should be NO context-switches
whatsoever when
running.
I did a quick speed-test against warpsnes: Running 'Super Mario World' from
where the screen
opens until the intro fades down(with options -nosound -f 2), and the results
where amusing :)
WarpSNES did the entire intro in 52 seconds, and this port flew thru it in just
32 seconds :D
Using -directhack did not change the time either. (As a side-note, WarpSNES had
to run in
320x256, as it did not like my 256x240 mode. Neither could I get WarpSNES to
work properly
on a 15/16-bit display, it just kept rendering as in 8-bit)
Keys are as follows:
Esc - Quit emulation
Up - Up on joypad 1
Down - Down on joypad 1
Left - Left on joypad 1
Right - Right on joypad 1
Z - A on joypad 1
A - B on joypad 1
X - X on joypad 1
S - Y on joypad 1
C - TL on joypad 1
D - TR on joypad 1
F1 - Toggle BG 0
F2 - Toggle BG 1
F3 - Toggle BG 2
F4 - Toggle BG 3
F5 - Toggle OBJs
F6 - Swap joypad 1/2
F8 - Swap layering
F9 - Toggle transparency
F10 - Toggle HDMA
There seem to be something fishy about the keyhandling right now, I'm working on
it. (Atleast with F1-F10)
Joypads can be connected to both ports, simulating both pads on the SuperNES.
