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 / Pokemon Fire Red
|
|||
|
|
|
|||
|
|
- Improve automatic 64k/128k flash save detection
|
|||
|
|
- Pok<6F>mon Emerald hangs with white screen when no save state exists and wrong flash size is selected (Flash 128)
|
|||
|
|
|
|||
|
|
- 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
|
|||
|
|
|
|||
|
|
- Game Bugs:
|
|||
|
|
- Drymouth - screen flashes black after certain scanline
|
|||
|
|
- World Reborn - 2 graphics bugs
|
|||
|
|
- V-Rally 3, Pseudo 3D flickering
|
|||
|
|
|
|||
|
|
Less important:
|
|||
|
|
- Add GBA cheat editing support (GB already has)
|
|||
|
|
- Look at Cheats.cpp (Core) and GBACheats.cpp (GUI)
|
|||
|
|
|
|||
|
|
- 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
|
|||
|
|

==========
|
|||
|
|
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.
|
|||
|
|
- Audio Sync + Auto frame skip break frames, causing emulation to drop to as low as 40fps even though enough performance is available to maintain full speed. Use one, or the other, not both. Vsync is not effected, and can be used with either setting.
|
|||
|
|
|
|||
|
|
- 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.
