General Issues and Todos.... - mudlord - 03-19-2008 06:50 AM

- Many games show emulation warnings in the log window (unaligned read, bad read/write address), due to inaccuracies in the core.
- Test: Metroid Fusion & Advance Wars

- Linking doesn't work quite right yet, due to core changes.
-> Cross platform linking might be a possibility under new Qt system

- Gb_Apu audio core: assertation error occurs when disabling GB sound

- Improve automatic 64k/128k flash save detection

- HQ3x/4x ASM implementation produces wrong interpolation on the image's border
See http://vba-m.com/forum/showthread.php?tid=32

- 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

Less important:

- 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
-> XySSL is a nice compact hash library. We need a DB of correct BIOSes though.

- 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

- VisualBoyAdvance Color Edition implementation

- Apply HQ3x/4x optimizations from C version to ASM version

- Apply pixel filter only to changed parts of the rendered image

- Make use of multi-core CPUs
-> To really make use of these, we need to multithread more parts of the core.
-> Could be a focal point on major Qt release

- Make use of 64 bit CPUs
-> Need to rewrite x86 ASM into x64 assembly
-> Could use YASM?

4xSaI would be nice xD

I would like to add in more issues:

- Cairo video backend does not properly render the gfx
- Filters does not yet work with Cairo and OpenGL backend
- An suspicious warning ** PortAudio : buffer underflow **

RE: General Issues and Todos.... - bgK - 06-13-2008 03:49 AM

The Cairo output module shows wrong colors when using filters. Known issue.
Filters work with OpenGL when using the GTK port. Try again.
PortAudio : buffer underflow means that the emulation does not go fast enough to feed the sound card. There will be blanks. That warning should be disabled.
