Allow mid-instruction VDP updates
make the breakpoint on disk header corruption an option in the debugger menu (off by default)NV file option ('N') is now allowed for cartridge memory space in non-banked cartridges onlyminimemory RAM is now non-volatile (weakly tested)emulator now sets the current folder to the same as classic99.exe by default
Fix for reading status of PROGRAM file images Related code shuffled
added cartridge eject to the menuadded CPU and GPU separate debug options (not certain they are 100%)fix certain reset issues by enabling a forced breakpointthrottling updates to improve consistencyadded tests for VRAM file buffers to aid debug of code that overwrites themfix disk access that writes right up to >3FFF (pCode card in particular)disable F18A status register select debugadd warning on odd PC address being setadd support for F18A GPU: CALL,RET,PUSH,POP,SLCupdated HQ4X filter - new filter code and should fix corrupted graphics in DIB blit modereduce duplicated debug when setting top of VRAM
fix bug with multi-bit CRU instructions - byte flag was set wrong way around and broke register auto-incrementadd support for F18A SPI flash interface (upgrade program runs now)also means that CKON, CKOFF, LDCR and STCR on the F18A work nowfix sector allocation when writing to disk image files to more closely match original TI controlleradd support for more of the F18A status registers and reading them from the hostmove source to Github - https://github.com/tursilion/classic99
