bsnes v0.053 released (2009-10-18)

This release greatly polishes the user interface, adds a new cheat code search utility, adds the snesfilter library, and adds Qt-based GUI support to both snesfilter and snesreader. snesfilter gains 2xSaI, Super 2xSaI and Super Eagle support, plus full configuration for both the NTSC and scanline filters; and snesreader gains support support for multi-file ROM archives (eg GoodMerge sets.)

Statically linking Qt to bsnes, snesfilter and snesreader would be too prohibitive size-wise (~10MB or so.) I have to link dynamically so that all three can share the same Qt runtime, which gets all of bsnes and its modules to ~1MB (including the debugger build); and Qt itself to about ~2.5MB.

However, there is some bad news. There´s a serious bug in MinGW 4.4+, where it is not generating profile-guided input files (*.gcno files.) There is also a serious bug in Qt 4.5.2/Windows when using dynamic linking: the library is hanging indefinitely, forcing me to manually terminate the process upon exit. This prevents the creation of profile-guided output files (*.gcda files.) It would be tough enough to work around one, but facing both of these issues at once is too much.

I´m afraid I have no choice but to disable profile-guided optimizations until these issues can be addressed. I did not know about these bugs until trying to build the official v053 release, so it´s too late to revert to an all-in-one binary now. And I´m simply not willing to stop releasing new builds because of bugs in third-party software. As soon as I can work around this, I´ll post a new optimized binary. In the mean time, despite the fact that this release is actually more optimized, please understand that the Windows binary will run approximately ~10% slower than previous releases. I recommend keeping v052 for now if you need the performance. Linux and OS X users are unaffected.

Changelog:

save RAM is initialized to 0xff again to work around Ken Griffey Jr Baseball issue

libco adds assembly-optimized targets for Win64 and PPC-ELF [the latter courtesy of Kernigh]

libco/x86 and libco/amd64 use pre-assembled blocks now, obviates need for custom compilation flags

added a new cheat code search utility to the tools menu

separated filters from main bsnes binary to libsnesfilter / snesfilter.dll

added 2xSaI, Super 2xSaI and Super Eagle filters [kode54]

added full configuration settings for NTSC and scanline filters (12+ new options)

further optimized HQ2x filter [blargg]

added Vsync support to the Mac OS X OpenGL driver

added folder creation button to custom file load dialog

updated to blargg´s file_extractor v1.0.0

added full support for multi-file archives (eg GoodMerge sets)

split multi-cart loading again (BS-X, Sufami Turbo, etc) as required for multi-file support
