Update to v095r04 release. Changelog: - S-SMP core code style updated - S-SMP loads reset vector from IPLROM ($fffe-ffff) - sfc/base => sfc/expansion - system/input => system/device - added expansion/eBoot (simulation of defparam's SNES-Boot device) - expansion port device can now be selected from Super Famicom menu option - improved GBA MROM/SRAM reading endrift's memory test is up to 1388/1552. Note: I added the expansion port devices to the same group as controller ports. I also had to move "None" to the top of the list. Before v096, I am going to have to add caching of port selections to the configuration file, check the proper default item in the system menu, and remove the items with no mappings from the input configuration window. Lots of work >_>

Update to v095r03 release and icarus 20151107. byuu says: Note: you will need the new icarus (and please use the "no manifest" system) to run GBA games with this WIP. Changelog: - fixed caching of r(d) to pass armwrestler tests [Jonas Quinn] - DMA to/from GBA BIOS should fail [Cydrak] - fixed sign-extend and rotate on ldrs instructions [Cydrak] - fixed 8-bit SRAM reading/writing [byuu] - refactored GBA/cartridge - cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash - things won't crash horribly if you specify a RAM size larger than the largest legal size in the manifest - specialized MROM / SRAM classes replace all the shared read/write functions that didn't work right anyway - there's a new ruby/video.glx2 driver, which is not enabled by default - use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet - I'm not going to support OpenGL2 on Windows/OS X, because these OSes don't ship ancient video card drivers - probably more. What am I, clairvoyant? :P For endrift's tests, this gets us to 1348/1552 memory and 1016/1260 timing. Overall, this puts us back in second place. Only no$ is ahead on memory, but bgba is even more ahead on timing.
