[TI99] Classic99 345 3/02/2011

Classic99 to emulator mikrokomputera Texas Instrument 99/4A z początku lat 80, jako ciekawostkę warto podać, że była to pierwsza konstrukcja przeznaczona dla domów opartą o 16bitową architekturę.

• Improve memory access timing by wrapping all CPU accesses (making sure the CPU always does 16-bit access)
• Fix cycle count patching in post_inc to be correct in all memory cases
• Removed extra RMW faking in certain opcodes
• Change default for "AllowTxtWithoutExtension" to false -- Windows TXT files must have a recognized extension
• Added support to read files without extension as DF128 (MUST have AllowTxtWithoutExtension set to 0 in the INI)
• Added hack to allow faking the SID back to the 9919 (not available outside of source code)
• Change interrupt flag to end_of_frame, and fix up the timing around that
• removed some old CPU memory wrapper functions that didn't do anything
• make sure we still check the VDP for redraw even if the CRU interrupt is masked (fixes rare case where screen did not update)
• Make sure the 9901 timer is not restarted when CRU bit 0 is cleared if it was not set
• Automatically set CPU Overdrive mode when pasting text
• Don't let console hardware respond to odd memory addresses
• Write VDP registers at the end of the VDPDUMP.BIN file
