VisualBoyAdvance-M
Nintendo Game Boy / Game Boy Advance Emulator
Based on official VBA
Original Project Homepage: vba.ngemu.com
New Project Homepage: vba-m.ngemu.com
The Qt build uses icons from the KDE project:
http://kde.org/
svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase/runtime/pics/oxygen
This program is distributed under the GNU General Public License

Aim:
Combine the best features of the VBA forks in one build.
Multi-platform support.
===================
System Requirements
===================
OS: Windows 2000 - Vista (x86 or x64), Linux
CPU: 700MHz minimum for GBA emulation, CPU requirements increase if filters are to be used.
RAM: ~64MB free
GFX: ~32MB VRAM, DirectX9 drivers
=================
Required Runtimes
=================

To Do List
==============
Important:
- Many games show emulation warnings in the log window (unaligned read, bad read/write address)
- Test: Metroid Fusion, Advance Wars 2
- Gfx.cpp/h optimization
- Test: Final Fantasy 4 airship intro
- Improve automatic 64k/128k flash save detection
- Add support for byuu's UPS patching format to replace IPS
- Remove 16 bit hack for filters
- Not compatible to software motion blur (display corruption)
- Add selection for compressed archives with more than one ROM in them
- Finalise Qt4 GUI system
- Fix LCD colouring
- Game Bugs:
* Drymouth - screen flashes black after certain scanline
* World Reborn - 2 graphics bugs
Less important:
- Add GBA cheat editing support (GB already has)
- Look at Cheats.cpp (Core) and GBACheats.cpp (GUI)
- Support D3DFMT_A2R10G10B10 (10 bit per color component) color format
- Add documentation for VBA-M (configuration guide)
- Improve AVI recording (produces asynchronous files)
- Enable audio stream compression for AVI files
- Add stereo upmixing support to OpenAL
- Verify BIOS files by checksum instead by file extension
- Merge HQ2x/LQ2x C code into code for HQ3x/4x
- Apply pixel filter to sprites and BG seperately for better image quality
Performance:
- Apply HQ3x/4x optimizations from C version to ASM version
- Apply pixel filter only to changed parts of the image
- Make even more use of multi-core CPUs
- Make use of 64 bit CPUs
- Have a look at the liboil optimization library
- http://liboil.freedesktop.org/wiki/
====================
Currently Known Bugs
====================
Known Bugs:
- Linking: Doesnt work quite right yet.
- Audio core: assertation error occurs when disabling sound in GB mode
- I think its best we mute sound instead, since some games rely on audio for timing.
Plus, blargg's GB_Snd_Emu is extremely optimized stuff. (Mudlord)
- blargg's core implementation broke Dwedit's GBC emu.
- Wrong bit depth image is displayed for 2 frames when switching from/to HQ3x/4x ASM
- This is caused by the 16bit hack which does not re-process the emulated image.
It results in the display devices treating the image at pix with the wrong bit depth.
