Short: SNES Emulator for PowerPC (WarpUP) V3.5
Author: MagicSN@Birdland.es.bawue.de (Amiga Port), chinoclast@softhome.net (Sound Code), Jeremy Koot and Gary Henderson (original Unix Version)
Uploader: MagicSN@Birdland.es.bawue.de
Type: misc/emu
New in V3.5:
- Sound Support !!! (Thanks go to chinoclast@softhome.net for his
GREAT Help in coding the sound stuff... actually it was more him
then me who coded the Sound... :) )
- Added latest version of SNES9xGUI (Sadly it seems to crash on exit,
because of this i also added the old version)
Options for AHI-Sound:
-nosound: Switch off Sound (Default: Sound is on)
-soundskip: values 0-3, only if sound is disabled
-soundquality:
0 - off
1 - 8192
2 - 11025
3 - 16500
4 - 22050 (default)
5 - 29300
6 - 33600
7 - 44000
Try a bit around what produces the best output !!! Also try
around with your AHI settings. Usually GOOD is:
* Paula = Set frequency as high as possible
* Sound Board = Set frequency to EXACTLY the one set in soundquality,
for example 22050
If the sound jerks, play around with the settings !!!
You can use a different AHI Unit by using
-ahiunit (Default=0)
-stereo (default)
-mono
-buffersize: 4096-32768 (default: 16384)
(Try playing around with this too... i think the default gives the
best results)
Important note to owners of Soundboards:
Appearently it does not work nice with Soundboard (at least not with
my Prelude). It only jerks. The same happens when i use my Soundboard
with Abuse 68k. I do not know if the hardware or the AHI Driver is
the problem.
There exists a
-prelude
Parameter for Prelude native sound. Not yet working in this version
of WarpSNES, use AHI !!!
The next version hopefully will also support SNES9x 1.18e changes. But
i wanted to finish sound-support first !!!
New in last version:
- Removed the AGA Speedup again, as it was incompatible with some games (actually
a LOT of games). These games then only crashed, even if called on a GFX Board
Screen. I now provided two versions of the executable, WarpSNES without the
AGA speedup, WarpSNES.old with it (but not all games run on WarpSNES.old).
WarpSNES is V3.4, WarpSNES.old is V3.3.
New in last version:
- Major speedup for AGA (thanks to the author of SNES9xPPC for hints)
Note: For optimal speed it is still recommended to use a CD32 Joypad.
Keyboard controls are rather slow. But AGA display now runs at 80%
of GFX Board Display.
- Now also works on systems without TCP/IP Stack installed (actually
removed TCP/IP part, as it still was not working... will reinsert it
later... now back to try to make the sound working :) )
New in last version:
- Adapted Sources to new-released SNES9x 1.10 (which means mainly that the DSP Emulation
improved so that more games run now, MarioKart *nearly* runs fine now)
- Changed Joypad Buttons, so that they come closer to the real SNES
- -minimal option added to switch of keyboard code with exception of ESC (did not
give much of a speedup, though)
- Network Support of 1.10 SNES9x (Untested, might not work)
- No unzip support of 1.10 SNES9x (but gzip Support works like always)
- Sound still does not work, sorry, also no ASM Optimizations yet... (maybe next
version...). If anybody has an idea about the sound, contact me :)
- fps should now show the real value for frameskip
- added a 4th GUI sent to me by the author, Johan Lundell (ghwerig@home.se).
Thanks for the Support :)
- Last version:
- frameskip now works. Note: the fps counter will show the
Frames Displayed / second
So the number will be much lower than your gaming feeling.
Somehow i am not sure if the number is displayed correct. If i
do -f 0 i get 36 fps, if i do -f 2 i get 15 fps, but the 15 fps
of -f 2 are definitely faster than the 36 fps :) The 36 fps are
correctly calculated however... somehow measuring goes strange
when frameskip is enabled... as the result looks much more like
50 fps than like 15 fps...
Use -f 0 to play with every frame displayed.
- Included a new version of SNES9xgui
- Included wsl GUI which by mistake was not included last time (instead
theguis.lha included an old version of WarpSNES last time... shame on me :) )
New in last versions:
- Lots of bugfixes
- If Subdirectory Snapshots exists, saving works
- Added 3 GUI's sent to me by different people. Use the one you like best :)
Thanks to Andreas Falkenhahn, Rune J. Keller and Sinan Gurkan for the
GUI's (personally i prefer snes9xgui from Andreas Falkenhahn)
- Note about the GUIs: The GUI of Andreas Falkenhahn sets the name of the
Emulator (it works with both WarpSNES and SNES9x for 68k) in a Tooltype.
The GUI of Sinan Gurkan assumes the name to be WarpSNES, the GUI of Rune J.
Keller enables the user to choose a name.
- Another note: Even if Andreas' GUI display's .zip'ed files, WarpSNES does not
run these. It can run gzip, not zip !!! That was a misunderstanding between
me and Andreas, hopefully fixed in the next version of the GUI :)
- BTW: WarpSNES now also runs .fig format, not only .smc !!!
- 15/16 Bit for *all* GFX Boards with WORKING Transparency effects
- Mousepointer is switched off during the game runs
- Still no sound, sadly. Hopefully next version :)
Notes:
- -speedhack gives 1-2 extra fps, but does not work with all games
- as long as sound does not work -nosound is also useful, gives 3-4 extra
fps normally
- 16 Bit looks much better than 15 Bit, and is not slower
- 256*256 Screenmodes enable a special optimization that gives 1 extra fps
- 15/16 Bit is only recommended for PPC 604e + Zorro III Boards, it really
pushes your system to its limits (on my system Earthworm Jim runs with
-speedhack -nosound on a 256*256 16 Bit Mode - RGB16PC - at around
24-25 fps... probably on a GFX Board without Byte-Swapping 16 Bit is
faster...)
- Byteswapping for 15/16 Bit is MUCH optimized. If anyone thinks he can
do better, contact me :) A piece of code to load 8 Bytes at once from
memory, Byteswap them and store them to memory, using lfdu/stfdu, would
be nice... currently i am using "4-Bytes at once".
New in the last version:
- "Wrong-Colors-Bug" of the first version (the colors looked dull at best)
fixed.
- Experimental 16 Bit Support integrated. Transparency currently lets things
look in very strange colors (Transparency can be toggled on/off by pressing
F10). 16 Bit currently only works on GFX Boards with RGB16PC GFX Modes (for
example Picasso IV or Piccolo SD64). I do NOT guarantee that you won't get
crashes in 16 Bit mode, activate it with -hicolor.
- stretch currently does not work (but why anyways, on Amiga you can do a
screenmode the size that you get Fullscreen !!!)
- hires support added (activate it with -hires)
- snes: assign is not needed anymore
- Loading of Compressed Files is now supported (use gzip to pack an Image
File, gzip should be on Aminet, and no, gzip is NOT the same like zip !!!)
The loading of the packed image files is very fast, as it is PPC Boosted :)
You then don't need the depacked images anymore on your harddrive. The
Emulator depacks them to RAM and starts them... :) Thanks to zlib...
If ANYBODY has an idea why 16 Bit stuff looks that strange, please tell me !!!
I will then add the 16 Bit support for the other GFX Boards, also... hopefully
the next versionwill also have sound-support. I also hope that till the next
version Phase 5 have ruled out the problems with their A1200-FlashROM-Software.
BTW: Remember to raise the stack to a higher value.
