VisualBoyAdvance-M
|
|
Nintendo Game Boy / Game Boy Advance Emulator
|
|
|
|
Based on official VBA
|
|

The Qt build uses icons from the KDE project:

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
|
|
|
|
|

File Dependencies
|
|
===================
|
|
|
|
"D3DX9_37.DLL" requires an update to DirectX.
|
|
You can use the following tool to update it:

|
|
|
|
In order to use OpenAL sound, the OpenAL runtime has to be downloaded and installed from http://openal.org/downloads.html
|
|
|
|
|

|
|
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
|
|
|
|
- Fix OpenGL issues
|
|
|
|
- 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
|
|
|
|
|
|
|
|
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
|
|
|
|
- Create Visual Studio project using SDL makefile
|
|
|
|
- Add device enumeration & buffer count selection for XAudio2
|
|
- Current buffer count: 4
|
|
|
|
|
|
|
|
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

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.
