Trying both arithmetically correct and more analytical approaches with varying success. Debug updates - Added ability to force all values to be equal to low precision values before operating on them - Added feature to test output of operations against a tolerance and print only those which fail GPU updates - Colour vertices with valid XY coordinates but no W as cyan to make them easier to spot - Remove cyan colouring for stale vertices (wasn't useful) - Added ability to skip debug rendering when needed (like seeing the output of offscreen rendering applied to a sprite). - Added new mode which shows primitive type 2016-07-04T10:48:00+00:00 iCatButler i.am.catbutler@gmail.com 2016-07-04T10:48:00+00:00 urn:sha1:97105b26f2194dcfb50addf0a421db9debd797d5 Validity of a pgxp value can now be set for any of four components using individual bit flags. This also allows the potential expansion of more flag data for each component. 2016-07-02T15:52:21+00:00 iCatButler i.am.catbutler@gmail.com 2016-07-02T15:52:21+00:00 urn:sha1:03cfe9e6c22044c5b6e333b90c2b0021842fffad - Change processor transfer functions to use take both source and destination values - Add enum values to all debug functions to double check instructions are correct - Temporarily store instruction codes in interpreter wrappers as these are sometimes changed by branching - Change recompiler wrapper functions to store register values in global variables in case they're changed by the original function 2016-06-27T14:28:33+00:00 iCatButler i.am.catbutler@gmail.com 2016-06-27T14:28:33+00:00 urn:sha1:42176205ce9ed9aa2408d4042a816fe5cd082519 - Change PGXP integration to use wrapper functions - Use modified function lookup tables to call wrappers or default funnctions based on mode - Implement wrappers for interpreter too, recompiler sometimes calls interpreter functions - Add UI elements for selecting CPU modes - Only call precision version of NCLIP in modes where there are not going to be stale vertices in GTE registers - Added support for CP0 co-processor functions - Improve support for CPU functions (still broken in many games) - Improved debug output to show values for inputs before they're modified GPU plugin - Ignore stale vertices (occurs when CPU mode no longer writes to memory) - Add Cyan vertex colouring for stale vertices 2016-06-07T14:57:46+00:00 iCatButler i.am.catbutler@gmail.com 2016-06-07T14:57:46+00:00 urn:sha1:f70082329d751ee8a358437feb34134e283b27d8 - Restructured project to base interface on PSX instructions - Support for all relevant CPU arithmetic and logic instructions - Debug output available via deferred PGXP calls - Remove most dependencies on PCSXR - Still very much a work in progress (lots of errors) - Add extra debug information to GPU plugin (w values)
