This is an experimental release, as such it is posted only to Google Code.
Changelog:
- 21fx API moved to pre-finalized form as S-MSU1; more about this on the forum
- OpenGL driver now uses GL_CLAMP_TO_BORDER instead of GL_CLAMP_TO_EDGE to support screen curvature shader
- rewrote file open dialog; code is greatly simplified, interface is improved
- all cheat code columns are now enquoted, and empty codes at the bottom of the file are omitted (format is compatible with previous releases still)
- debugger: added missing DMA variables to S-CPU properties viewer
- snesfilter: added OpenMP (multi-threading) support to HQ2x filter
- lots of other miscellaneous code cleanup work
