Beta 3: (Probably 2-4 weeks to go)

- Merlin RTG board blitter fixed. 86box ET4000 blitter/MMU was incomplete (No linear blitter/MMU apertures, missing blit start mode check, pattern/source alignment restrictions are ET4000w32p only). Added vblank interrupt and monitor switcher support. Fixed horizontal panning in 24-bit modes. Overlay/PIP not yet implemented. It is quite useless because overlay and main bitmap depth must match.
- Added oMniBus RTG board (Zorro II to ISA adapter). ET4000AX (no blitter, no HW cursor) or ET4000W32 (blitter and HW cursor. Note: Current Picasso96 drivers have a bug that makes ET4000W32 blitter unusable, bug that apparently has always been in this driver. Fix will be in next Picasso96 release.)
- Added Graffity Z2/Z3 RTG board. Cirrus Logic GD5428 based. Has monitor switcher.
- Added Rainbow II "RTG" card. Not really proper RTG card, has only hardwired PAL and NTSC resolutions (768x576 and 768x476). 24-bit depth only. Note that emulation always refreshes whole screen every frame (not just modified parts but whole screen) which is not very optimal but it really isn't worth the trouble because I am sure now one cares about this old board.
- Some hardware emulated RTG boards had flickering colors during horizontal panning (>8 bit modes only)

- Small PCI emulation changes (For example G-REX + Permedia 2 + some other PCI card: same card appeared 8 times)
- Added Apollo 630 emulation and boot ROM 5.61. Nothing special, ROM is only used to detect the RAM: "32Bit Power-Burstmode-FastRAM", apparently cool sounding name can make RAM even faster! (oddly ROM contains at least parts of IDE and SCSI drivers from other Apollo accelerators).

- In a rare situation it was possible to get false positive "CPU Trace" error when loading statefile.
- Debugger breakpoint "f 123 <extra parameters>" didn't work, "<extra parameters>" was incorrectly detected as PC end address even when it wasn't a number.
- Programmed mode with only VARVBEN enabled (Programmed vblank but hardwired syncs) didn't check if programmed VB ended earlier than hardwired PAL/NTSC vblank, resulting in vblank ending too late, hiding part of display at the top. (ross test(tm))
- If strobe conflicts start after STREQU strobes but before first STRHOR strobes: Denise vblank state stays stuck active until next valid STRHOR strobe is seen by Denise. (SOS / Triangle + ECS Agnus). Interesting detail: If OCS Denise, STRVBL strobe DOES NOT enable vblank (fixed in ECS Denise). Only STREQU strobes enable vblank. STRHOR disables vblank.
- OCS Denise "buggy" vblank start/end (visible only in Overscan+ and higher) start/end position was 2.5 CCKs too early.
- Left and right A1000 Denise/OCS Denise/ECS Denise hardwired hblank position slight adjustments (1 hires pixel) to match new test results.
- Both "SaveImage" (automatically created ext adf when write-enabling non-writable image like ipf) file extension variants are now detected automatically when checking if file exists. Paths panel option now only affects name when new saveimage is created.

All Picasso96 supported RTG boards are now emulated. All CGX4 supported boards except Inferno. Inferno can't work, only known Wildfire boot ROM fails to configure it properly. PCI config logic seems to get confused if PCI BAR size is too large (GD5446 is 16M or 32M depending on revision). It seems Inferno support needs newer boot ROM which may not have been officially released. Apparently Inferno was also never officially released. EGS not tested, reports accepted if someone really wants to check EGS drivers.
