Version 0.2:
- add experimental support for Super Game Boy, including Super Game
Boy borders.
- add support for emulation speedup.
- add support for forcing emulation mode (Game Boy, Color Game Boy
or Super Game Boy) in Configuration File.
- improved accuracy for startup state.
RealBoy is a Free, Fast, Yet Accurate, Game Boy/Game Boy Color
Emulator for Linux/Unix. It has both technical as well as educational
goals.
Technically, it aims for the following:
1) Accuracy. Perhaps the most important technical goal, as seen in
the best closed-sourced emulators, such as KiGB and BGB, and some
free emulators, such as Gambatte and MESS.
2) Performance. Show that it is possible to implement a very fast
emulator without sacrificing accuracy.
3) Feature-rich. Implement advanced features such as a flexible
internal debugger.
* Included Linux image works fine on NetBSD/amd64 6.99.23
Changelog:
New features
Addition of ports to Amiga OS 3 and OS 4.
Sound emulation.
Support for RAM sizes other than 4MB (512KB, 1MB, 2MB,
4MB, 8MB, 12MB & 16MB now supported).
ARM250 & ARM3 CPU emulation.
ArcEm clock set from host's clock, partial RTC support.
Extension ROM emulation, allowing support for the
following new features when emulation RISC OS:
HostFS - A RISC OS filesystem to allow use of a
directory on the Host Filing system as a virtual
hard drive.
Mouse scroll wheel support.
Extra video modes, up to 1024x768 in 16 colours and
800x600 in 256 colours.
Bug fixes/Improvements
Many performance tweaks and optimisations, resulting in
a 5-6 times performance gain on ARM hosts. A 600MHz
XScale can now achieve a level of performance roughly
equivalent to an 8MHz ARM2. Similar performance gains
can be seen on other low-power hosts.
Video emulation rewritten to provide accurate redraw
and VSync timing, down to the scanline level.
Video emulation now supports upscaling and aspect ratio
correction for rectangular pixel modes.
All hardware clocks/timers (IOC timers, video DMA, audio
DMA, etc.) now run in real time, ensuring one second
takes one second no matter how fast the host machine
is.
Source code tidied a bit to remove redundant code,
including support for emulation of 32bit processor modes
(there are other, much better emulators for that!).
Source code converted to use C99 number types to aid
portability.
Instruction prefetch now correctly emulated - ensures
correct operation with self-modifying code and some
forms of copy protection.
RISC OS version now 32bit compatible, and ARMv7-safe.
Also much more useable with modern machines/LCD monitors
as it no longer requires the host to be able to support
Archimedes screen modes.
Windows version updated to build under Visual Studio
2010 (including Express edition).
Unix/X11 version now supports X servers that don't
support XWarpPointer.
PDP-10 KL10B model emulator. KL10B model supports extended addressing.
Tap networking support is from http://www.falu.nl/~rhialto/klh-diffs2 .
This package is potentially built on i386, amd64, arm, alpha, sparc,
and powerpc platforms. But this package supports i386 and amd64 only now,
and only amd64 build is tested, due to lack of my test environments.
