Michal Schulz (Mail) Motorola68k emulation: Emu68 v1.0 Release Candidate 3
Developer Michal Schulz has released Release Candidate 3 of version 1.0 of his Motorola68K emulation Emu68 for the ARM architecture, focusing on the PiStorm and PiStorm32lite (amiga-news.de reported). Emu68 1.0 Release Candidate 3 is the last release candidate before final version 1.0. It includes all fixes from RC1 and RC2. Additionally it contains several changes and fixes improving performance of old games and demos:

BlitWait

The BlitWait option allows the user to force Emu68 to do more fine-grained waits before writting several blitter-sensitive registers. Normally, the software which is using blitter should wait until it completed the operation, but in some cases the demo coders assumed that m68k is slow enough to not waist time for waiting. Such games and/or demos require the blitwait option activated either through cmdline.txt or with help of EmuControl to operate properly.

Ability to add EmuControl parameters to Emu68 globally

With this release user can pass the EmuControl command line options, like e.g. DBF ICNT=1 CCRD=0 directly to cmdline.txt file and thus making them global. This, in combination with eventually disabled CPU caches, allows one to run demos like the "State of the Art" directly from floppy, without WHDLoad.

RGB to HDMI Passthrough

This feature requires small external hardware (work in Progress or A500, A600, A1200, A2000) which sends the digital RGB data through the camera interface to raspberry directly. IN combination with new unicam.resource (embedded in kernel) and new VideoCore/Emu68-VC4 driver (available in new nightly build of Emu68-tools) this allows to display the RGB signal from Amiga on the HDMI. The unicam.resource allows one to enable this feature on boot already, new VideoCore driver allows one to easily switch between RGB and RTG modes on the same screen.

The developer provides more detailed information on the changes in his new Patreon post. (dr)
