VZ80remix - found some inconsistancy #34

@Emulog-SVG

Description

@Emulog-SVG

IM column in TraceLog reflects IM mode, but actual IM mode is still not shown.
ei, im 2, im 1, nop - issue int inside im1 and sequence ends at 0038h. If 2T late reflection be correct then IM2 sequence must appear, but not.

missing so called "IFF3 and IFF4", one catch NMI at any t-state, second masks NMI acception until RETN RETI.
Usual RET in NMI ISR do not enable NMI acception back.

with inc hl opcode i see active reg_ee0 #1821, labels incorrect

missing BUSRQ and BUSAK, missing PCR2 and PCR1, missing H/LBUS in TraceLog, these be quite convenient for emulator development

These issues come too late though, but someone may need this.
