Relative path improvement broke CDFS CD mounting in some configurations.
Ungrab (b4) event didn´t disable mouse capture when it was activated in fullscreen modes.
VPOS LOF bit toggles (if interlace) exactly 2 cycles before first refresh slot. Logic analyzer tested.
Copper vblank strobe also stopped the copper if DMA was disabled and second strobe register was accessed previously. Broke in 280b1. (Sequential / Andromeda first screen)
More accurate BPL1DAT emulation. (Glitches appeared in Sequential / Andromeda magnet part´s left border when one pixel gap in Rink a Dink / Lemon rotozoomer part white border was fixed)
8-bit split (odd/even) roms didn´t load if merged parent was missing.
New relative path mode worked badly under Windows XP, possibly up to Windows 7 without SP1.
"Toggle between mouse grabbed and un-grabbed" input event has not done anything at all for ages (if ever).
"Switch between audio interpolation methods" input event probably has never done anything at all, probably totally useless (custom events works as well) but at least it works now..
