History
-------
BETA RELEASE 1
- Initial release
BETA RELEASE 2
- Now supports any size on roms. (Only limited by the memory available)
- Rendering-routines now display graphics on GFX-boards. (CGFX tested OK)
- Removed the exclusive flag on the emulation screen.
- Added user-control over frame skip and emulation speed.
- Screen is now double-buffered to avoid flickering.
- SNES PAL/NTSC modes emulated correctly.
- Fixed bug in CPU, permitting 2 new rom's to display their graphics.
- Starting to implement several BG's.
- Mode 0 semi-implemented.
- Configuration saved on exit. Last accessed path saved in configuration.
- Builtin debugging system semi-implemented.
- Graphics are now rendered in fastmem and then copied to chipmem. This
gives great improvements when fastmem is available. Chip-only users
will not lose speed on this, as within the copy, the BG-merge occurs.
- DMA and hardware for OAM added.
- VRAM accessing errors fixed.
Requirements
------------
Processor: MC68020+
OS Version: 3.x
Graphics: AGA or GFX-board
Memory: 500kB memory MINIMUM (FASTMEM is HIGHLY recommended!)
This program uses reqtools.library (© 1991-1994 Nico François,
1995 Magnus Homgren) for the filerequesters.
Usage
-----
Should be self-explaining thanks to the very simple GUI.
Main Menu
---------
Open ROM - Opens a file-requester and after that loads and tries to
identify the ROM header. The ROM is NOT loaded into memory
at this point.
Start Emulator - Loads the ROM into memory and tries to execute it. If you
get a emulator-error right after clicking, you might be
too low on memory.
ROM Info - Opens a small window with some information about the
selected ROM image.
Preferences - Opens program preferences.
About - A small about requester.
Quit - Now WHAT could this button do? :)
Preferences
-----------
ROM Force - Used to force a romimage into a certain mode. As the emulator
itself only supports LowROM's, it's recommended to select
'Force to LowROM'. Demos REQUIRE this due to their arbitrary
size.
DWrite - No effect currently, but will soon affect the way the screen
is updated. Non AGA-users are recommended to keep this switch
turned OFF.
CyberGFX - No effect currently, but will allow CGFX users to actually run
the emulator within a window. This will at LEAST require 15 bit
highcolor.
Skip - SNES Screenrender frame skip. Currently a bit unreliable, but
will use more correct routines soon.
Speed - Sets the speed of the 65816 CPU. Can be useful when running
small demos that don't use the CPU much. Too low values may
affect screen-updates. Can make great improvements on speed
if combined with 'Skip'.
Debugging requester
-------------------
Ok - Exits the emulation and brings you back to the menu.
Continue Emulation - Continues to emulate the SNES where it left off.
Enter Debugger - Launches AmiSNESE's built-in debugger.
Debugger
--------
Single Step - Step one instruction. Graphics are NOT updated.
One Frame - Run an entire frame of code. Graphics are updated.
Abort Emulation - Exits the emulation and brings you back to the menu.
Cont. Emulation - Continues to emulate the SNES where it left off.
FAQ
---
Q: I'm using a graphics-card, but I can STILL not get any graphics
displayed when launching your emulator!
A: Try to promote the screenmode into something your gfx-board supports,
it should solve the problem.
Q: Where can I find the rom's that you show screen-shots off on the
homepage?
A: I've now added some non-commercial ROM's to the page, allowing you
to test the emulator.
