Short: UAEGfx/UltraHD for UAE/OS4 Author: Holger.Hippenstiel AT gmx.de Uploader: Holger Hippenstiel nc-online de Type: driver/video Version: 1.1 Replaces: driver/video/UAEGfxForOS4.lha Architecture: ppc-amigaos Distribution: Aminet Kurz: UAEGfx/UltraHD fuer UAE/OS4 UAEGfx/UltraHD for UAE/OS4 V1.1 =============================== You got OS4 running on (Win)UAE, got P96 installed, but only got PicassoIV-Emulation with 4MB VRam, hence can only use low resolutions ? Here is a simple solution ! You need: http://aminet.net/package/driver/video/Picasso96 Delete/Move any Devs:Monitors/#? Copy from the P96-archive Devs/Monitors/Picasso96 to Devs:Monitors/UAEGfx Copy from the P96-archive Libs/Picasso96/uaegfx.card to SYS:Kickstart Copy from this archive UAEGfx.info to Devs:Monitors Set your Workbench to PAL/NTSC Highres Laced. Wait 3 Seconds. Close the UAE running. Set your RTG-Board to UAE Zorro III with 64MB (or more if you like). Check "Match host and RTG color depth if possible" Check "Multithreaded" Check "Hardware sprite emulation" Select "Color modes" with an (*) in the right columns - if possible. If you had PicassoIV-Emulation before, go to "Expansions" -> "Graphics boards" -> "Picasso IV" -> select the empty row on the right. Save your config. Load your config (WinUAE has a bug when just doing restart still partially using old settings). Start the emulation, wait till Workbench has loaded, then choose any Resolution you like including 3840x2160 Pixels. :D FAQ: Which resolutions can i use ? This depends on how much VRam you assign to the UAEGfx-Card and which resolutions your real gfx-card supports. You can caluculate the needed VRam roughly: width*height*4/1024/1024 So for 3840*2160 it's 31.4 MB - but keep in mind that workbench-pictures and so on also need VRam. Resolutions bigger than 3840x2160 are possible, for example i can choose 5120x2880 even on a Intel Celeron J3355 (10W Part) with an IGP HD500 - because the Intel-driver supports this resolution. Can i add own resolutions ? Yes and no, dont try to add resolutions in Prefs:Screenmode, it will change the Arguments in UAEGfx.info and it will no longer work. Add own resolutions to your real gfx-card, then they will show up under UAEGfx aswell (after a restart). Can i use PicassoIV or an other P96-Card at the same time as UAEGfx? No, this doesnt work. WinUAE supports multiple RTG-Cards, but if you try to add an PicassoIV, the UAEGfx-screen will be garbage - others like Picollo SD64 dont cause this problem, but wont start in OS4. It seems P96 only supports one card, or maybe because the 68k-Emulationpart of P96 is running it causes problems. The workbench shows a different memorysize than i have entered for UAEGfx? Start Prefs:Workbench and change the Title-Formatline, after %g change %mvm to %mgm Can't you add part of the UAEGfx-Ram to the OS4 memory? In theory yes, like i did for the EGS-Spectrum: http://aminet.net/package/util/boot/AddEGS it works as long as 68k is running (and i wont release it for 68k either, because Picasso96 doesn't use the expansion-entrysize and will overwrite the memory when higher resolutions are used), but OS4 wont use this memory, it will show up as a free memoryblock in for example http://aminet.net/package/util/moni/Scout_os4 but you may notice there is only the chipram listed, even with http://aminet.net/package/util/boot/TLSFMem which completly redos the memorysystem OS4 wont use the additional memory. WarpOS/OS4 handles memory-allocations differently.
