What does it do: With the contents of this arhive it is possible to run WarpOS software on AmigaOS4 systems like AmigaOne, classic Amigas, SAM440ep, SAM460, A1222 and X1000 abd X5000. The WarpOSEmu from Joerg Strohmayer does not work on some of the newer systems and this was an attempt to fix it. It also contains a Warp3D wrapper which should enable you to play WarpOS Warp3D games on AmigaOS 4.1. Restrictions: Same restrictions apply as with the WarpOSEmu software from Joerg Strohmayer. Most notably the lack of sound in some of the WarpOS games. Some bang the Amiga classic hardware directly which is a sure thing to break this wrapper. Also with the newer supported Warp3D V5 cards, it has become apparant that compatibility has decreased with Warp3D V4. The Warp3DPPC wrapper should work fine with Voodoo and Permedia2 cards, but shows drawing errors or hangs with the (newer) Radeon cards. If this happens please test with Wazp3D from Alain Thellier and ReWarp together first to rule out an error in ReWarp. ReWarp3DPPC itself is just a call forwarder and should not be the source of any errors. Some of the fixes Alain put into Wazp3D and PatchWarp3D are optional patches you can switch on as an ENV. See below. Options: The library supports options through ENVARC:Warp3DPPC. Supported are: - PatchDrawElements: Use Alain Thellier's patch for W3D_DrawElements. - PatchDrawArray: Use Alain Thellier's patch for W3D_DrawArray. - PatchDrawLine: Use Alain Thellier's patch for W3D_DrawLine. - PatchAll: Use all of the above. Default is that none are enabled. Recommended is PatchAll. This has been tested on a Sam440 with a Radeon 9200 on AmigaOS 4.1FE In the archive: powerpc.library: Library that functions as a wrapper to redirect WarpOS calls to the AmigaOS4 kernel. Warp3DPPC.library: Library that functions as a wrapper to redirect Warp3DPPC calls to native AmigaOS4 Warp3D.library. env: Folder containing the ENV options for easy use. Notes: Regarding the version numbering: Original powerpc.library runs up to 16.1. WarpOSEmu continues the number up to 46.x. The powerpc.library for the PPC PCI cards uses 17.x version numbering. This one uses 18.x version numbering. This is just to make a distinction between the different powerpc libraries. The future: At the moment there are no future plans. ReWarp works fine using WarpOS apps that don't use custom exceptions (iFusion, wosdb). Software rendering of Quake, Quake II, Shogo, Heretic II and all the other WarpOS games should work fine (with some having sound problems; see above). Some need to use system calls to render (no direct framebuffer manipulations allowed). Another story is with the Warp3DPPC wrapper. As said, V4 compatibility with the newer graphics cards has become worse. Some errors with the Radeon R200 cards could be solved by using patches but not all. V4 can use indirect rendering and V5 does not for example. Any patches to improve compatibility are welcome.
