(1)The patch is no longer required, as you well know. The fact that is still listed on OS4depot is unfortunately misleading.
(2)Greyscale rendering? Not here. Ham8 on screen.
(3)VistaPro - You confused me on another site. I thought you had 24bit preview on screen, so I said nothing. You should have Ham8 preview in huge size, if you wish to.
I see you accepted mixing "screens" (OS4PPC) with "modepro" (68k). As long as you accept the usage of modepro, there are far easier ways to achieve your goals. I reached the point after promoting this program with 3 different methods, that modepro alone offered the flexibility to perform certain tricks.
To all unfamiliar with the threads in question that MBrantley refers to, I would be happy to supply links. I had posted, amongst other things the idea of having at least one member OS4/MorphOS/AROS form irc channel to co-operate on getting some old favorites running, when so possible.
